Information and Ideas practice question

The monarch butterfly migrates up to 3,000 miles from Canada and the United States to central Mexico each fall. Remarkably, no single butterfly makes the entire round trip; the journey spans several generations.

According to the text, which statement is true of the monarch migration?

  1. A. A single butterfly completes the full round trip.
  2. B. The migration is completed over multiple generations.Correct
  3. C. Monarchs migrate only within Mexico.
  4. D. The migration happens in the spring.

Answer: B. The migration is completed over multiple generations.

The text says the journey 'spans several generations' and that no single butterfly makes the round trip, so B is directly stated and A is contradicted. C and D conflict with the described route and season.

Why the other answers are wrong

A. A single butterfly completes the full round trip.
The text says directly that 'no single butterfly makes the entire round trip,' so this is the exact statement the passage contradicts.
C. Monarchs migrate only within Mexico.
Mexico is the destination, not the whole range — the migration starts in Canada and the United States and covers up to 3,000 miles.
D. The migration happens in the spring.
The text specifies the butterflies migrate to Mexico 'each fall,' not in spring.
