DISCUSSION: The passage tells us quite a bit about Harris sparrows. The best thing to do is choose 1-2 answer choices that seem plausible, and try to confirm one of them using information from the passage.
___________
- Plumage doesn’t signal status for Harris sparrows.
- CORRECT. Adult Harris sparrows have higher status (lines 31-33), and high status birds have greater access to resources (lines 5-7).
- “Relatively dark” could mean 0.05% darker, which is nothing. The adult might still be darker.
(Plumage in Harris sparrows does weakly indicate status, by indicating adulthood, see lines 33-35) - We’re never told how often Harris sparrows fight.
- Same as D.
