Chapter: Language, Style & Conventions

What this practice covers

By the end of Academic (Tier 2) Vocabulary you should be able to:

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

Vocabulary used: Tier 2 vocabulary, context clues, nuance.

Problem 1

Which word is a Tier 2 (general academic) word, rather than Tier 1 or Tier 3?
  1. happy
  2. photosynthesis
  3. significant
  4. run
Answer and explanation

significant

'Significant' is a general academic word used across many subjects, unlike the everyday Tier 1 words ('happy,' 'run') or the subject-specific Tier 3 word ('photosynthesis').

Problem 2

Explain the difference between Tier 1, Tier 2, and Tier 3 vocabulary, with one example of each.
Answer and explanation

Tier 1 words are everyday words like 'walk'; Tier 2 words are general academic words used across subjects, like 'analyze'; Tier 3 words are technical, subject-specific terms, like 'mitochondria.'

Problem 3

'Although the data seemed to support her claim, closer analysis revealed several inconsistencies.' Based on context, 'inconsistencies' most likely means…
  1. strong points of agreement
  2. contradictions or mismatches within the data
  3. a type of graph
  4. the final conclusion
Answer and explanation

contradictions or mismatches within the data

The contrast word 'Although' plus 'closer analysis revealed' signal that inconsistencies are problems or contradictions found upon further examination.

Problem 4

Use the Tier 2 word 'consequently' correctly in an original sentence about a topic of your choice.
Answer and explanation

Answers vary; accept any sentence where 'consequently' correctly signals a cause-and-effect relationship, such as, 'The bridge was closed for repairs; consequently, traffic on Main Street doubled.'

Problem 5

A writer uses the word 'ubiquitous' to describe smartphones. Based on the sentence 'Smartphones have become so ubiquitous that finding someone without one is now unusual,' what does 'ubiquitous' most likely mean?
  1. Extremely rare
  2. Present or found everywhere
  3. Expensive and exclusive
  4. Outdated and old-fashioned
Answer and explanation

Present or found everywhere

The clue 'finding someone without one is now unusual' implies smartphones are present nearly everywhere — that's the meaning of 'ubiquitous.'

Problem 6

Infer rescinded and test the meaning by substitution. Give a detail and explain its relevance.
Answer and explanation

Rescinded means canceled or withdrawn. Replacing it with “canceled” preserves the explanation that permission is no longer required.

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: “Tentative means lazy because she has not finished.” Explain the problem and produce a better response.
Answer and explanation

Use the sentence’s evidence of uncertainty rather than a judgment about effort. A dictionary can confirm whether the inference fits the word’s usage.

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

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. The method transfers, but the particular detail, scope, and context must be read again. Rescinded means canceled or withdrawn. Replacing it with “canceled” preserves the explanation that permission is no longer required.

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 academic (tier 2) vocabulary. Aim for 180–250 words; name the reading or reproduce the sentence you revise.
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. 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 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. Ask for a relevant detail and the reason it supports the conclusion. Prioritize the mistaken assumption shown here: “Tentative means lazy because she has not finished.”

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 archive proposal values participation, the historian asks for traceable uncertainty, and the resident asks for consent. A labeled memory layer with dates and participant approval connects these concerns without turning memory into the original map. 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.
