Question

which two sentences from the article include central ideas of the article?

1. then the philadelphia eagles won the super bowl in february.
2. but not that long ago, the bald eagle was in danger of dying out in the u.s.
3. but things have been looking up for bald eagles since the early 2000s.
4. an insecticide is a chemical that is used to kill or control insects.

a 1 and 2
b 1 and 4
c 2 and 3
d 3 and 4

Explanation:

• Sentence 1 is about a sports team (Philadelphia Eagles) winning the Super Bowl, which is likely a detail rather than a central idea about bald eagles (assuming the article is mainly about bald eagles).
• Sentence 2 presents a key situation - the bald eagle was in danger of dying out in the U.S., which is a significant point about the bald eagle's past status.
• Sentence 3 shows a change (things looking up for bald eagles since the early 2000s), which is another important aspect of the bald eagle's story (its recovery or improvement in situation).
• Sentence 4 is a definition of an insecticide, which is likely a supporting detail (maybe explaining a cause of the bald eagle's past danger if insecticides were harmful to them) but not a central idea about the bald eagle's overall story (its endangerment and recovery).

C. 2 and 3
