ACT® · English: Topic Development — Relevance, Focus, and Deletion
Plausible but Potentially Irrelevant at a Given Point (TOD 601)
A sentence can be true and well-written and still be wrong for its spot. Relevance depends on what the paragraph has already told the reader by that point, not on whether the fact is useful somewhere in the essay.
The hardest deletion questions don't give you a bad sentence. They give you a good one, placed wrong. The trap is judging the sentence on its own merits — is it true, is it well written, is it interesting — instead of asking whether the reader needs it right here. A sentence's job is to help the reader at the exact moment they reach it. If the paragraph has already made the point another way, or will make it better later, the sentence stalls the paragraph instead of building it.
To test a sentence, slide it through the paragraph in your head and watch where it stops pulling weight. A definition of a term is useful the first time that term shows up, confusing or redundant the third time. A detail about how something works is useful in the paragraph that is actually about how it works, not in a paragraph about when it was built. So 'this detail gets used later' is never a reason to keep a sentence here — it's a reason to move it there. The question is always local: given everything said so far in this paragraph, does this sentence add something new and needed?
This connects directly to the other deletion skill, redundancy: both ask 'does this sentence earn its place,' just from different angles — repeats what's already known versus arrives at the wrong moment. The twist to watch for is the reverse case: a sentence that looks like throwaway background can be the paragraph's only number or only piece of evidence for its claim. Before deleting, check what the paragraph loses, not just what the sentence repeats.
Key terms
- Relevance
- Whether a sentence adds something the reader needs at the exact point it appears, not elsewhere in the essay.
- Focus
- The specific angle or question a paragraph is built around, which decides which true facts belong in it.
- Redundant placement
- When a sentence repeats or restates something the paragraph has already established before that point.
- Local judgment

Watch it explained
- How it worksHow does a sentence's relevance depend on what the reader already knows at that exact point?
- How it worksWalk me through sliding one sentence through a paragraph and watching where it stops helping.
- Common mistakeWhy isn't 'the essay uses this detail further down' a reason to add it here?
- Worked exampleFind whether a sentence defining sonar belongs before or after a paragraph that already used the word twice.
- Going furtherWhat changes when the plausible sentence is the only place an essay gives an actual number?
