Craft and Structure practice question
Many people assume that yawning cools the brain. But a recent study found no difference in brain temperature before and after yawning, suggesting the popular explanation may be incomplete.
What is the main purpose of the text?
- A. To prove that yawning has no biological function
- B. To question a common explanation using new evidenceCorrect
- C. To describe how yawning spreads between people
- D. To argue that more people should study yawning
Answer: B. To question a common explanation using new evidence
The text raises a common belief, then presents evidence that undercuts it ('may be incomplete'). That's questioning a claim, not proving a stronger one (A overstates). Purpose questions reward the most measured option.
Why the other answers are wrong
- A. To prove that yawning has no biological function
- This overstates the text: it says the popular explanation 'may be incomplete,' which questions one explanation rather than proving yawning has no function at all.
- C. To describe how yawning spreads between people
- The text never mentions yawning spreading between people — it discusses brain temperature and one specific explanation.
- D. To argue that more people should study yawning
- No call for more research appears; the text reports what one study found and what that implies about a common belief.
