Question

how does sentence 3 in the passage support the central ideas? choose two answers. it gives evidence for deforestation causing a big change in biodiversity. it describes how few species are affected by deforestation. it gives a reason why deforestation can affect many species. it provides a cause of deforestation in tropical areas.

Explanation:

To solve this, we analyze each option (assuming the passage is about deforestation and biodiversity):

1. "It gives evidence for deforestation causing a big change in biodiversity." – If the passage’s central idea relates to deforestation’s impact on biodiversity, this option explains how sentence 3 provides evidence (e.g., data/ examples) for that impact.
2. "It describes how few species are affected by deforestation." – This is incorrect because deforestation typically affects many species, not few.
3. "It gives a reason why deforestation can affect many species." – If the central idea is about deforestation’s effect on species, this option explains how sentence 3 provides a causal reason (e.g., habitat loss) for why deforestation impacts many species.
4. "It provides a cause of deforestation in tropical areas." – This is off - topic if the central idea is about deforestation’s impact on biodiversity (not the causes of deforestation).

Answer:

A. It gives evidence for deforestation causing a big change in biodiversity.
C. It gives a reason why deforestation can affect many species.

(Note: The option labels are adjusted as the original "It describes how few species..." is incorrect, and the fourth option is off - topic. The correct two are the first and the third as analyzed.)
