The Informative Essay — Practice · Grade 8 English

Chapter: Research & Source-Based Writing

What this practice covers

By the end of The Informative Essay you should be able to:

11 questions, multiple choice and written answer, each with a worked explanation.

Vocabulary used: informative/explanatory writing, transition, domain-specific vocabulary.

Problem 1

The main goal of informative writing is to...
  1. explain a topic clearly and accurately
  2. persuade the reader to agree with an opinion
  3. tell an entertaining personal story
  4. argue against a counterclaim
Answer and explanation

explain a topic clearly and accurately

Informative writing aims to clearly and accurately explain a topic, unlike argumentative or narrative writing.

Problem 2

Which organizational structure would best fit an essay explaining the similarities and differences between two ecosystems?
  1. compare and contrast
  2. process or sequence
  3. argumentative structure
  4. narrative structure
Answer and explanation

compare and contrast

Comparing similarities and differences is the exact purpose of a compare/contrast structure.

Problem 3

Name a topic and the organizational structure (definition, compare/contrast, cause/effect, or sequence) you would use to explain it, and explain why.
Answer and explanation

A strong answer names a real topic and justifies the structure choice, for example: 'Explaining how a volcano erupts would use a cause/effect structure, since pressure building underground directly causes the eruption.'

Problem 4

Which sentence uses a transition to connect ideas clearly?
  1. As a result, the water level rose sharply after the storm.
  2. The water level rose sharply after the storm.
  3. The storm happened on a Tuesday.
  4. Storms can be measured in several ways.
Answer and explanation

As a result, the water level rose sharply after the storm.

'As a result' is a transition that explicitly signals a cause/effect relationship between two ideas.

Problem 5

Which of these does NOT belong in an objective, informative essay?
  1. Honestly, this is the most important invention in human history.
  2. The invention was patented in the late nineteenth century.
  3. The device relies on a simple electrical circuit.
  4. Several later inventions were based on this design.
Answer and explanation

Honestly, this is the most important invention in human history.

The first sentence inserts a personal opinion, which doesn't belong in objective, informative writing.

Problem 6

Plan three sections with a clear distinction. Give a detail and explain its relevance.
Answer and explanation

Use sections on changing places, new evidence about old places, and corrections of earlier records. This separates an actual change in land use from a change in what historians know.

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: “This essay explains surveys: surveys are amazing and everyone should answer ours.” Explain the problem and produce a better response.
Answer and explanation

Replace promotion with a clear explanation of purpose, method, results, and limits.

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

An informative essay explains a question without requiring the reader to accept a policy position. Choose a clear focus and organize by meaningful categories or a sequence. The method transfers, but the particular detail, scope, and context must be read again. Use sections on changing places, new evidence about old places, and corrections of earlier records. This separates an actual change in land use from a change in what historians know.

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 the informative essay. Aim for 120–180 words; name the reading or reproduce the sentence you revise.
Answer and explanation

The survey asked 60 volunteers about later library hours, and 45 supported the change. Because participation was voluntary, the results describe respondents rather than every student. A broader survey would require a different sampling plan. 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 an informative essay explains a question without requiring the reader to accept a policy position. choose a clear focus and organize by meaningful categories or a sequence. Ask for a relevant detail and the reason it supports the conclusion. Prioritize the mistaken assumption shown here: “This essay explains surveys: surveys are amazing and everyone should answer ours.”

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 sources agree that access matters but differ on how to estimate demand and fund supervision. The survey suggests interest among respondents; the restricted materials grant cannot pay wages. A funded attendance trial addresses the uncertainty. 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.
