Question 1: What is the main idea?
Main Idea: The main idea is the most important point the author wants to convey. It summarizes the overall message of the passage.
Let’s look at the options:
a.
Bats are mammals.
→ This is not mentioned in the passage at all. So this is
not correct.
b.
Bats eat 600 mosquitoes in one hour.
→ This is a specific detail, not the main idea. It supports the larger point but doesn't summarize the whole passage. So this is
not correct.
c.
Bats eat many insects.
→ This is supported by multiple sentences: "Some kinds of bats eat many insects," and "They help us by eating insects." Also, the fact that they eat 600 mosquitoes is an example of this. The passage emphasizes how bats are helpful because they eat insects.
This option captures the
central idea — that bats are beneficial because they consume insects.
✔ Correct answer: c. Bats eat many insects.

Question 2: What is one supporting detail?
A
supporting detail is a fact or example that helps explain or prove the main idea.
From the passage:
- "Some bats can eat up to 600 mosquitoes in one hour."
- "Without bats, we would have too many insects."
These are both details that support the main idea that bats eat many insects and are helpful.
So, one good supporting detail is:
➡️
"Some bats can eat up to 600 mosquitoes in one hour."
This shows *how* bats eat many insects, giving evidence for the main idea.
---
✔ Final Answers:
-
Main Idea: c. Bats eat many insects.
-
One Supporting Detail: Some bats can eat up to 600 mosquitoes in one hour.
