Writing and Composition
What the questions test
Composition questions assess whether you can build a clear thesis, organize coherent paragraphs, maintain unity and focus, and use transitions that reflect the real logical relationship between ideas. You should recognize the elements of an effective introduction (context plus claim), body paragraph (topic sentence, evidence, commentary), and conclusion (synthesis, not mere repetition). Questions may ask you to choose the best sentence to insert, the most logical order of sentences, or the best revision of an awkward passage.
Traps to watch for
- Off-topic but well-written sentences: fluency is not relevance; a graceful sentence that drifts from the paragraph's focus is still wrong.
- Misused transitions: however signals contrast, therefore signals cause, for example signals illustration. Inserting the wrong connector breaks logic.
- Redundancy and wordiness: the best revision is usually the most concise version that preserves meaning.
- Vague pronoun or modifier placement: misplaced modifiers and unclear this or it create ambiguity.
Rule of thumb
For sentence-insertion or ordering questions, identify the topic sentence and the logical chain first, then test each option by asking: does it advance the paragraph's single controlling idea, and does the transition match the relationship? Prefer the choice that adds necessary information without repeating what is already stated.
Worked example
A paragraph argues that urban trees reduce heat. A candidate sentence about the beauty of autumn foliage is attractive but shifts focus from temperature to aesthetics, so it disrupts unity. A sentence noting that shaded pavement stays measurably cooler directly supports the claim and belongs.
