Reading the passage
Shelter, lower body temperature, and fatty seeds: the opening birds show different ways to survive a cold night. Then the writer turns to kinglets, whose survival isn't fully explained. I'd look for an answer about those known survival methods.
Working the answers
- ACorrect
Each bird is paired with a way of saving or obtaining energy. The examples introduce how winter survival can work before we reach the puzzling kinglet case.
- B
Simply identifying which birds survive misses why we're told about the tree hollows, torpor and seeds. Those details explain methods of survival, not just membership in a list of successful birds.
- C
No comparison with birds elsewhere establishes that these adaptations occur only in North America. The geographic setting doesn't support that restriction.
- D
These aren't presented as established kinglet strategies. The later discussion finds no evidence of torpor in kinglets, and their exclusive insect diet differs from the seed diet described here.
- E
Different examples don't prove each species has a unique method. Other species could share the strategies. The writer needs examples, not exclusive ownership of each one.
