Direct answer

The scope trap is answering from topic overlap while ignoring who or what is covered, all vs some vs none. A statement about “students” may be false if the passage limits the claim to “postgraduate students.” Before True, False, or Not Given, ask: does the passage include the same group, exclude the same group, and say nothing about the rest?

Why coverage beats topic words

Passages narrow groups with modifiers: most, a minority, only, except. Statements often sound universal. Examiners test whether you track the same population, not the same noun.

Universal bait Statement says all; passage says many or some
Hidden subset Passage limits to one country; statement says worldwide
None vs not all Passage says few; statement says none, different claims

Scope mismatches that repeat

Pairs with qualifier traps and extreme word traps.

Framework: match coverage before meaning

1. Name the group

Who or what does the statement claim to cover? Underline it.

2. Find the limiter

Search the proof line for only, except, most, few.

3. Three-way check

Same group, smaller group, or undefined → True, False, or Not Given.

4. Timed TFNG blocks

Eight statements in 12 minutes with a scope column in review.

Key takeaways

  • Scope tests who is included, all, some, or none, not topic words alone.
  • Universal statements fail when the passage names a subset.
  • Separate “not all” from “none”: they are different claims.
  • Pair scope checks with qualifier and extreme-word review.

FAQ

Overlap exists, scope is coverage (all, some, none); qualifiers add degree (often, may). Test both.
When the statement names a group the passage never defines, no proof of all or some.
Yes, options often share topic words but change whether everyone, most, or no one is included.
