DISCUSSION: Support the right answer using the passage. There’s not much else to say.
- This is unlikely. Lines 53-57 say that pine forests in Nicaragua went away when humans lefts. Human fires are non-random, while natural fires are random.
- Lines 32-34 say that mature forests do have herbaceous undergrowth.
- The passage argues that natives had a big impact. That doesn’t mean settlers didn’t also have a big impact.
- CORRECT. Lines 35-37 support this. Berries were more common because of fires, for example.
- Hard to say. The passage implies that controlled burning is different from natural fires, which are random. Lines 53-57 say that the pine forests disappeared when humans weren’t around.
