RC Question 15 Explanation
DISCUSSION: You need to find something mentioned in both passages. Many wrong answers talk about things that only one passage mentions.
___________
- Only passage A deals with this.
- Passage A seems to assume that all invasive species are by definition bad.
- Passage B doesn’t even seem to think a protective approach is needed.
- CORRECT. Passage A argues the ecosystems are weakened. Passage B argues that they simply change.
- Passage A mentions this in the third sentence of paragraph 1, but Passage B doesn’t say how species can spread to new habitats.
Hello, I know answer choice E is wrong, but just out of curiousity, wouldn’t passage A saying “ecologists realize that when humans introduce new species into existing ecosystem” (lines 8-9) actually be considered an idea of how invasive species arrive in the new ecosystems? I know passage B doesn’t mention anything so eliminated this answer primarily based on that.
Oh, you’re right, that is a way: human introduction. I edited the explanation, thanks.
