Language, Style & Conventions — Problem set, Grade 9

Edit a passage from your own draft for meaning, sentence boundaries, agreement, punctuation, word choice, and citation. Submit original and revised versions with explanations of six purposeful changes.

Review the key ideas

Syntax & Sentence Variety

Syntax is the arrangement of words and clauses. Sentence length, clause order, repetition, and punctuation can direct attention and pace.

Semicolons, Colons & Parallel Structure

Parallel structure uses matching grammatical forms for items doing similar work. It helps readers compare choices without accidental shifts.

Tone, Diction & Register

Diction is word choice; register is language adapted to an audience, setting, and purpose. Neither formal nor informal wording is best for every situation.

Academic (Tier 2) Vocabulary

Use the surrounding sentence and paragraph to infer a word’s meaning, then check a reliable dictionary when needed. Grammatical role and word parts narrow possibilities but do not guarantee a meaning.

Problem 1

Combine the ideas to emphasize the tension. Explain the evidence or language choice.
Answer and explanation

“Although the wall looked welcoming, it removed the speaker’s qualification.” The dependent clause concedes an appearance while the main clause emphasizes the substantive loss.

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 2

Explain the method behind this unit’s grade-specific application. Give a different detail or sentence from an assigned text and show how the method applies.
Answer and explanation

The repeated clauses accumulate measurable achievements; the short final sentence interrupts that rhythm with an omission. Its emphasis depends on the contrast, not simply on being short. A parent should check accuracy of meaning, suitability for the context, and a clear explanation of the relevant convention or evidence.

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 3

Revise the list and explain the improvement. Explain the evidence or language choice.
Answer and explanation

“The workshop teaches planning, drafting, and revising.” Matching -ing forms show three processes at the same grammatical level.

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 4

Explain the method behind this unit’s grade-specific application. Give a different detail or sentence from an assigned text and show how the method applies.
Answer and explanation

Use a colon after “things” because a complete clause introduces a list: “The archive needs three things: dated records, permissions, and space for disagreements.” The list items are not independent clauses. A parent should check accuracy of meaning, suitability for the context, and a clear explanation of the relevant convention or evidence.

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 5

Revise for a formal report without overclaiming. Explain the evidence or language choice.
Answer and explanation

“The committee reported that volunteers collected 23 bags of litter; it did not test water quality.” The revision replaces vague praise and unsupported proof with a specific, limited statement.

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 6

Explain the method behind this unit’s grade-specific application. Give a different detail or sentence from an assigned text and show how the method applies.
Answer and explanation

Both can suit their contexts. The archive request names the action and information needed; the casual request relies on shared context. Formality alone is not the reason one works better for the archive. A parent should check accuracy of meaning, suitability for the context, and a clear explanation of the relevant convention or evidence.

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

Infer tentative and explain the clue. Explain the evidence or language choice.
Answer and explanation

Tentative means provisional or uncertain here. The two dates and request for verification show that she has not presented the account as settled.

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

Explain the method behind this unit’s grade-specific application. Give a different detail or sentence from an assigned text and show how the method applies.
Answer and explanation

Rescinded means canceled or withdrawn. Replacing it with “canceled” preserves the explanation that permission is no longer required. A parent should check accuracy of meaning, suitability for the context, and a clear explanation of the relevant convention or evidence.

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.
