Information and Ideas practice question
Hedgehogs hibernate through the winter, dropping their heart rate from about 190 beats a minute to fewer than 20. Every few weeks they wake briefly to drink. A hedgehog that is disturbed and wakes too often can burn through its stored fat before spring arrives.
According to the text, why is waking too often dangerous for a hibernating hedgehog?
- A. Each waking uses up fat reserves that have to last until spring.Correct
- B. Its heart rate falls too low to recover.
- C. It cannot find water in winter.
- D. It forgets how to return to sleep.
Answer: A. Each waking uses up fat reserves that have to last until spring.
The last sentence states it: waking too often can burn through stored fat before spring.
Why the other answers are wrong
- B. Its heart rate falls too low to recover.
- The low heart rate is part of normal hibernation, not the danger described.
- C. It cannot find water in winter.
- The text says hedgehogs wake to drink; it doesn't say water is unavailable.
- D. It forgets how to return to sleep.
- Nothing about forgetting appears in the text.
