Research & Source-Based Writing — Chapter Practice, Grade 10

Develop a focused research question about the assigned book or the source packet’s issue. Collect and evaluate additional verifiable sources, build an evidence matrix, and write a source-based explanation or argument.

Problem 1

Which of these is the MOST focused, researchable question?
  1. How has the use of AI plagiarism-detection tools changed the way one district's teachers grade essays since 2023?
  2. Tell me everything about AI in schools.
  3. What is artificial intelligence?
  4. Is artificial intelligence dangerous?
Answer and explanation

How has the use of AI plagiarism-detection tools changed the way one district's teachers grade essays since 2023?

Only this option names a specific application, group, outcome, and timeframe — narrow and answerable, unlike a definition, a yes/no opinion, or an open-ended demand.

Problem 2

Explain why a researcher might deliberately broaden a question partway through a project, and give one sign that broadening is the right move.
Answer and explanation

If there is almost no credible evidence available on the exact narrow angle chosen, the question needs to broaden — widening the population, timeframe, or outcome — so there is enough to research and support a thesis. A clear sign is repeatedly searching and finding only a handful of thin or unrelated sources.

Problem 3

Which question is 'researchable' — specific enough to answer with evidence, but too complex to settle in a single search?
  1. Is public transportation nicer than driving?
  2. Why did bus ridership in one city keep falling even after fares were made free?
  3. What is public transportation?
  4. In what year was the first electric car built?
Answer and explanation

Why did bus ridership in one city keep falling even after fares were made free?

A researchable question needs evidence gathered and weighed. The others are a lookup fact, a matter of taste, and a definition — none require real investigation.

Problem 4

Take the broad topic 'social media' and narrow it into one focused, researchable question.
Answer and explanation

Answers vary; accept any specific, answerable how/why question, such as, 'How has the shift to disappearing-story features changed how often teenagers post about political issues?' It should name a specific factor, group, or outcome rather than the whole topic.

Problem 5

Deep into a project, a student finds that their question — 'How does technology affect learning?' — returns tens of thousands of studies across dozens of contradictory angles, with no way to cover them. What is the BEST next step?
  1. Keep the question as is and rely on personal experience instead of sources.
  2. Abandon the project and pick a completely new topic.
  3. Narrow the question to one specific technology, one group of learners, and one measurable outcome.
  4. Try to briefly summarize all of the angles so nothing is left out.
Answer and explanation

Narrow the question to one specific technology, one group of learners, and one measurable outcome.

When a question is too broad to manage, the right move is to add specific limits — a particular technology, population, and outcome — not to abandon the project or attempt shallow coverage of everything.

Problem 6

Narrow the inquiry without presuming bias. Give a detail and explain its relevance.
Answer and explanation

Ask how the mural program represents a named worker’s role compared with the archive records. Analyze what each source includes, its purpose, and omissions; visitor comments may show responses but not the full audience.

Use the criteria to compare your reasoning, not to copy the model’s wording. A supported alternative interpretation may earn full credit.

Response criteria

  • Make an accurate, focused claim or revision.
  • Use a relevant detail or a clearly explained language choice.
  • Explain the relationship and recognize a relevant limit.

Problem 7

A learner writes: “Why are all public displays misleading?” Explain the problem and produce a better response.
Answer and explanation

The question assumes a universal answer. Specify a display and ask how excerpt selection affects the representation of speakers.

Use the criteria to compare your reasoning, not to copy the model’s wording. A supported alternative interpretation may earn full credit.

Response criteria

  • Make an accurate, focused claim or revision.
  • Use a relevant detail or a clearly explained language choice.
  • Explain the relationship and recognize a relevant limit.

Problem 8

Compare what you must inspect in these two cases. What can transfer, and what must be checked again?
Answer and explanation

Turn a broad topic into a question with a manageable place, time, population, and purpose. A question should require inquiry rather than assume its answer. The method transfers, but the particular detail, scope, and context must be read again. Ask how the mural program represents a named worker’s role compared with the archive records. Analyze what each source includes, its purpose, and omissions; visitor comments may show responses but not the full audience.

Use the criteria to compare your reasoning, not to copy the model’s wording. A supported alternative interpretation may earn full credit.

Response criteria

  • Make an accurate, focused claim or revision.
  • Use a relevant detail or a clearly explained language choice.
  • Explain the relationship and recognize a relevant limit.

Problem 9

Using an assigned reading or one exercise source, write a developed response applying research questions & inquiry. Aim for 220–320 words; name the reading or reproduce the sentence you revise.
Answer and explanation

Ask whether a twice-weekly later opening at this school attracted enough use to justify its staffing cost during the trial. Compare the attendance log and budget, then interview staff about supervision limits. A complete response supplies context, a focused claim, a brief supporting detail, explanation, and a relevant qualification. Do not simply repeat this model.

Use the criteria to compare your reasoning, not to copy the model’s wording. A supported alternative interpretation may earn full credit.

Response criteria

  • Make an accurate, focused claim or revision.
  • Use a relevant detail or a clearly explained language choice.
  • Explain the relationship and recognize a relevant limit.

Problem 10

Write two specific feedback comments on a response to this unit: one on accuracy or meaning and one on evidence or language. Then state a revision priority.
Answer and explanation

Check whether the response explains turn a broad topic into a question with a manageable place, time, population, and purpose. a question should require inquiry rather than assume its answer. Ask for a relevant detail and the reason it supports the conclusion. Prioritize the mistaken assumption shown here: “Why are all public displays misleading?”

Use the criteria to compare your reasoning, not to copy the model’s wording. A supported alternative interpretation may earn full credit.

Response criteria

  • Make an accurate, focused claim or revision.
  • Use a relevant detail or a clearly explained language choice.
  • Explain the relationship and recognize a relevant limit.

Problem 11

Choose a fresh sentence or detail from the assigned selection. Explain how this unit’s method applies, and identify one uncertainty or limitation.
Answer and explanation

The report documents litter removal, the resident distinguishes water contamination, and the memo separates funding purposes. The event can be successful within its stated scope while water quality remains unresolved. The response must supply its own precise detail and explain it; copying the model without fresh evidence is insufficient.

Use the criteria to compare your reasoning, not to copy the model’s wording. A supported alternative interpretation may earn full credit.

Response criteria

  • Make an accurate, focused claim or revision.
  • Use a relevant detail or a clearly explained language choice.
  • Explain the relationship and recognize a relevant limit.

Problem 12

Which source is generally MOST credible for a research question about the safety of a new prescription drug?
  1. A testimonial on the drug maker's marketing page
  2. A viral post claiming the drug 'changed my life'
  3. A comment left under a video, with no name or sources
  4. A peer-reviewed clinical study in a medical journal
Answer and explanation

A peer-reviewed clinical study in a medical journal

A peer-reviewed clinical study is vetted by outside experts and relies on verifiable methods, making it the most credible option; the others have unknown authorship or a clear promotional motive.

Problem 13

Explain the difference between a primary and a secondary source, using an example of each connected to a scientific discovery.
Answer and explanation

A primary source is firsthand or original, like a scientist's raw experimental data or original lab notes; a secondary source analyzes or interprets that material afterward, like a science journalist's article or a textbook summarizing the discovery. The primary source is the evidence itself; the secondary source is someone's interpretation of it.

Problem 14

A student's research question is about how sleep affects TEENAGERS' test scores. They find a rigorous, peer-reviewed study — but it studied only adults over 40. What is the best judgment?
  1. The source is credible but not directly relevant to teenagers, so it shouldn't be treated as direct evidence for this question.
  2. Reject the source as worthless because it must be biased.
  3. Change the research question to match whatever the source studied.
  4. Use it as strong evidence, since any peer-reviewed study is credible enough.
Answer and explanation

The source is credible but not directly relevant to teenagers, so it shouldn't be treated as direct evidence for this question.

A source can be perfectly credible yet not relevant to your specific question; a study of adults over 40 does not directly answer a question about teenagers, so it can't stand as direct evidence here.

Problem 15

Why does the 'currency' of a source matter far more for a question about cybersecurity threats than for a question about the causes of World War I? Give your reasoning.
Answer and explanation

Cybersecurity changes constantly — new threats and defenses appear every year — so an old source may describe a landscape that no longer exists and mislead the researcher. The causes of World War I are historically settled and change very little over time, so well-researched older sources on that topic can remain reliable. Currency matters most for fast-changing subjects.

Problem 16

A student finds a dramatic statistic on an unfamiliar website, but cannot locate the original study it claims to cite anywhere else. What is the BEST course of action?
  1. Use the statistic, since it is specific and sounds convincing.
  2. Treat the statistic with skepticism and avoid using it unless the original source can be verified independently.
  3. Cite the website as the original researcher of the statistic.
  4. Round the statistic off to make it easier to defend.
Answer and explanation

Treat the statistic with skepticism and avoid using it unless the original source can be verified independently.

An unverifiable claim shouldn't be trusted as evidence; careful researchers triangulate — confirming a striking statistic against its real, checkable origin before relying on it, or leaving it out.

Problem 17

Decide how to use the sources. Give a detail and explain its relevance.
Answer and explanation

Trace the count to the original report and check whether attendance includes a different group. Until that distinction is documented, cite the report’s 38 volunteers and label the larger claim unverified.

Use the criteria to compare your reasoning, not to copy the model’s wording. A supported alternative interpretation may earn full credit.

Response criteria

  • Make an accurate, focused claim or revision.
  • Use a relevant detail or a clearly explained language choice.
  • Explain the relationship and recognize a relevant limit.

Problem 18

A learner writes: “A .org address guarantees an unbiased source.” Explain the problem and produce a better response.
Answer and explanation

An address describes registration, not evidence quality. Investigate authorship, funding, method, and corroboration.

Use the criteria to compare your reasoning, not to copy the model’s wording. A supported alternative interpretation may earn full credit.

Response criteria

  • Make an accurate, focused claim or revision.
  • Use a relevant detail or a clearly explained language choice.
  • Explain the relationship and recognize a relevant limit.

Problem 19

Compare what you must inspect in these two cases. What can transfer, and what must be checked again?
Answer and explanation

Evaluate expertise, access to evidence, method, publication context, purpose, date, and traceability. These are questions to investigate, not a scorecard based on appearance. The method transfers, but the particular detail, scope, and context must be read again. Trace the count to the original report and check whether attendance includes a different group. Until that distinction is documented, cite the report’s 38 volunteers and label the larger claim unverified.

Use the criteria to compare your reasoning, not to copy the model’s wording. A supported alternative interpretation may earn full credit.

Response criteria

  • Make an accurate, focused claim or revision.
  • Use a relevant detail or a clearly explained language choice.
  • Explain the relationship and recognize a relevant limit.

Problem 20

Using an assigned reading or one exercise source, write a developed response applying evaluating sources. Aim for 220–320 words; name the reading or reproduce the sentence you revise.
Answer and explanation

The company has a sales interest, but that alone does not prove the count false. Ask for sample size, measurement, selection and comparison; the claim cannot establish tutoring caused the improvement without those details. A complete response supplies context, a focused claim, a brief supporting detail, explanation, and a relevant qualification. Do not simply repeat this model.

  • Explain the relationship and recognize a relevant limit.

Problem 22

Choose a fresh sentence or detail from the assigned selection. Explain how this unit’s method applies, and identify one uncertainty or limitation.
Answer and explanation

The report documents litter removal, the resident distinguishes water contamination, and the memo separates funding purposes. The event can be successful within its stated scope while water quality remains unresolved. The response must supply its own precise detail and explain it; copying the model without fresh evidence is insufficient.

Problem 23

Which is a correctly formatted MLA in-text citation for an idea found on page 47 of a book by author Idris Bello?
  1. (Bello, page 47)
  2. (Idris 47)
  3. (Bello 47)
  4. [Bello: 47]
Answer and explanation

(Bello 47)

MLA in-text citations use the author's last name followed directly by the page number, with no comma, no 'page' label, and no brackets: (Bello 47).

Problem 24

When should a writer use a direct quotation instead of a paraphrase? Give one situation where quoting is the better choice.
Answer and explanation

A direct quotation is best when the source's exact wording carries weight that a paraphrase would lose — for example, a strikingly memorable phrase, a precise technical definition, or wording the writer wants to analyze closely. For most ordinary facts and ideas, paraphrasing or summarizing is better so the writing stays in the writer's own voice.

Problem 25

Which of these is a signal phrase?
  1. Furthermore,
  2. (Roy 12)
  3. In conclusion,
  4. According to marine biologist Dr. Nadia Roy,
Answer and explanation

According to marine biologist Dr. Nadia Roy,

A signal phrase introduces a source by naming who is speaking, like 'According to marine biologist Dr. Nadia Roy'; it isn't a transition word or the parenthetical citation itself.

Problem 26

A student copies a sentence from an article and changes only three or four words, adds no quotation marks, and includes no citation. Is this plagiarism? Explain.
Answer and explanation

Yes. Swapping a few words is not a genuine paraphrase — it keeps the source's sentence structure and phrasing, a practice sometimes called patchwriting — and without quotation marks or a citation, the reader would believe the phrasing and idea are the student's own. A real paraphrase rebuilds the idea in new words and structure and is still cited.

Problem 27

A student integrates a quotation perfectly with a signal phrase and cites it as (Okafor 30), but the paper's Works Cited page has no entry for Okafor. What is the problem?
  1. There is no problem; a signal phrase makes the Works Cited entry unnecessary.
  2. The in-text citation is incomplete without a matching Works Cited entry, since a reader needs both to identify and find the source.
  3. The page number should have been left out of the citation.
  4. The quotation should have been paraphrased instead.
Answer and explanation

The in-text citation is incomplete without a matching Works Cited entry, since a reader needs both to identify and find the source.

In-text citations are short pointers that only work alongside a full Works Cited entry; without it, a reader can't trace (Okafor 30) to an actual, findable source.

Problem 28

Explain why this is not yet a sound paraphrase. Give a detail and explain its relevance.
Answer and explanation

The wording remains nearly identical. Quote the phrase accurately, or recast the idea genuinely: Lee argues that labels should indicate where the evidence remains incomplete. Attribution is still needed.

Use the criteria to compare your reasoning, not to copy the model’s wording. A supported alternative interpretation may earn full credit.

Response criteria

  • Make an accurate, focused claim or revision.
  • Use a relevant detail or a clearly explained language choice.
  • Explain the relationship and recognize a relevant limit.

Problem 29

A learner writes: “Changing three words means I no longer need a citation.” Explain the problem and produce a better response.
Answer and explanation

Borrowed ideas still need attribution, and borrowed distinctive wording needs quotation marks. Rewriting is not a numerical word-substitution rule.

Use the criteria to compare your reasoning, not to copy the model’s wording. A supported alternative interpretation may earn full credit.

Response criteria

  • Make an accurate, focused claim or revision.
  • Use a relevant detail or a clearly explained language choice.
  • Explain the relationship and recognize a relevant limit.

Problem 30

Compare what you must inspect in these two cases. What can transfer, and what must be checked again?
Answer and explanation

A citation allows readers to trace borrowed words and ideas. MLA in-text references direct readers to a Works Cited entry, adding an available locator such as a page number when appropriate. The method transfers, but the particular detail, scope, and context must be read again. The wording remains nearly identical. Quote the phrase accurately, or recast the idea genuinely: Lee argues that labels should indicate where the evidence remains incomplete. Attribution is still needed.

Use the criteria to compare your reasoning, not to copy the model’s wording. A supported alternative interpretation may earn full credit.

Response criteria

  • Make an accurate, focused claim or revision.
  • Use a relevant detail or a clearly explained language choice.
  • Explain the relationship and recognize a relevant limit.

Problem 31

Using an assigned reading or one exercise source, write a developed response applying integrating evidence & citation. Aim for 220–320 words; name the reading or reproduce the sentence you revise.
Answer and explanation

If Lee is not named in the sentence, use (Lee); if the prose already names Lee, do not repeat it without a locator. The entry uses Lee, the article title, the site title, date, and URL. Do not add a made-up page. A complete response supplies context, a focused claim, a brief supporting detail, explanation, and a relevant qualification. Do not simply repeat this model.

Use the criteria to compare your reasoning, not to copy the model’s wording. A supported alternative interpretation may earn full credit.

Response criteria

  • Make an accurate, focused claim or revision.
  • Use a relevant detail or a clearly explained language choice.
  • Explain the relationship and recognize a relevant limit.

Problem 32

Write two specific feedback comments on a response to this unit: one on accuracy or meaning and one on evidence or language. Then state a revision priority.
Answer and explanation

Check whether the response explains a citation allows readers to trace borrowed words and ideas. mla in-text references direct readers to a works cited entry, adding an available locator such as a page number when appropriate. Ask for a relevant detail and the reason it supports the conclusion. Prioritize the mistaken assumption shown here: “Changing three words means I no longer need a citation.”

Problem 33

Choose a fresh sentence or detail from the assigned selection. Explain how this unit’s method applies, and identify one uncertainty or limitation.
Answer and explanation

The report documents litter removal, the resident distinguishes water contamination, and the memo separates funding purposes. The event can be successful within its stated scope while water quality remains unresolved. The response must supply its own precise detail and explain it; copying the model without fresh evidence is insufficient.

Problem 34

Which of these is an example of TRUE synthesis, not just summary?
  1. Explaining that Source A and Source B reach opposite conclusions because they measure different outcomes, then drawing an original point about what that reveals.
  2. Three quotations copied in a row with no sentences of the writer's own.
  3. Source A says X. Source B says Y. Source C says Z.
  4. One paragraph explaining Source A, then a separate paragraph explaining Source B, with no link between them.
Answer and explanation

Explaining that Source A and Source B reach opposite conclusions because they measure different outcomes, then drawing an original point about what that reveals.

True synthesis names the relationship between sources and adds the writer's own analysis, rather than listing, isolating, or copying them separately.

Problem 35

Explain how two credible sources can seem to disagree when they actually don't. Give an example.
Answer and explanation

Two sources can appear to conflict when they are really answering different questions or measuring different outcomes. For example, one study finding that remote work boosts productivity and another finding that it increases loneliness are not in conflict — one is about output and the other about well-being. A strong synthesis names this distinction rather than forcing the sources into a false disagreement.

Problem 36

Which paragraph structure BEST reflects strong synthesis?
  1. Quotation, quotation, quotation, with no explanation.
  2. An original claim, then evidence braided from multiple sources with signal phrases and citations, then the writer's analysis connecting it back to the claim.
  3. A single source summarized at length, with no other sources mentioned.
  4. A list of citations with no sentences connecting them.
Answer and explanation

An original claim, then evidence braided from multiple sources with signal phrases and citations, then the writer's analysis connecting it back to the claim.

Strong synthesis leads with the writer's own claim, weaves in multiple properly introduced sources as support, and closes with original analysis — point, proof, meaning.

Problem 37

Two sources disagree: one argues that requiring community-service hours for graduation builds civic commitment, while another argues that mandatory service breeds resentment and 'hour-padding.' Write one or two sentences that synthesize both into an original insight, rather than just reporting each.
Answer and explanation

Answers vary; look for signal phrases introducing both viewpoints and an original concluding thought — for example, noting that whether a service requirement builds commitment or resentment may depend less on the mandate itself than on whether students get real choice in how they serve, a trade-off neither source fully resolves.

Problem 38

A student finds one strong, credible study that contradicts their thesis. They are tempted to leave it out to keep the essay simple. Why is this the wrong move?
  1. Contradicting sources can never be used in a research paper anyway.
  2. It isn't wrong; leaving out inconvenient evidence makes an argument cleaner.
  3. Ignoring credible contradicting evidence is dishonest and actually weakens the essay, since informed readers may know the evidence and a one-sided paper looks evasive.
  4. It is wrong only because the study would have added more citations to the Works Cited page.
Answer and explanation

Ignoring credible contradicting evidence is dishonest and actually weakens the essay, since informed readers may know the evidence and a one-sided paper looks evasive.

Honest synthesis concedes and engages its best opposition; hiding a credible contradicting source is dishonest and makes the argument look uninformed or evasive to a knowledgeable reader.

Problem 39

Synthesize without pretending all sources agree. Give a detail and explain its relevance.
Answer and explanation

A labeled evidence panel could add agency while preserving a welcoming mural and attributing historical claims. The sources still differ on priorities; the proposal answers overlapping concerns rather than eliminating disagreement.

Use the criteria to compare your reasoning, not to copy the model’s wording. A supported alternative interpretation may earn full credit.

Response criteria

  • Make an accurate, focused claim or revision.
  • Use a relevant detail or a clearly explained language choice.
  • Explain the relationship and recognize a relevant limit.

Problem 40

A learner writes: “All three sources discuss the museum, so they prove the same thesis.” Explain the problem and produce a better response.
Answer and explanation

A shared topic is not shared reasoning. State each position and connect specific agreements, conflicts, and conditions.

Use the criteria to compare your reasoning, not to copy the model’s wording. A supported alternative interpretation may earn full credit.

Response criteria

  • Make an accurate, focused claim or revision.
  • Use a relevant detail or a clearly explained language choice.
  • Explain the relationship and recognize a relevant limit.

Problem 41

Compare what you must inspect in these two cases. What can transfer, and what must be checked again?
Answer and explanation

Synthesis organizes several sources around your question or claim. It is more than a paragraph summarizing Source A followed by a paragraph summarizing Source B. The method transfers, but the particular detail, scope, and context must be read again. A labeled evidence panel could add agency while preserving a welcoming mural and attributing historical claims. The sources still differ on priorities; the proposal answers overlapping concerns rather than eliminating disagreement.

Use the criteria to compare your reasoning, not to copy the model’s wording. A supported alternative interpretation may earn full credit.

Response criteria

  • Make an accurate, focused claim or revision.
  • Use a relevant detail or a clearly explained language choice.
  • Explain the relationship and recognize a relevant limit.

Problem 42

Using an assigned reading or one exercise source, write a developed response applying synthesis writing. Aim for 220–320 words; name the reading or reproduce the sentence you revise.
Answer and explanation

The sources agree on the value of access but reveal an unfunded staffing condition. A limited trial could test demand only after identifying wage funding; the materials grant cannot be treated as available staffing money. A complete response supplies context, a focused claim, a brief supporting detail, explanation, and a relevant qualification. Do not simply repeat this model.

Use the criteria to compare your reasoning, not to copy the model’s wording. A supported alternative interpretation may earn full credit.

Response criteria

Choose a fresh sentence or detail from the assigned selection. Explain how this unit’s method applies, and identify one uncertainty or limitation.
Answer and explanation

The report documents litter removal, the resident distinguishes water contamination, and the memo separates funding purposes. The event can be successful within its stated scope while water quality remains unresolved. The response must supply its own precise detail and explain it; copying the model without fresh evidence is insufficient.
