Let’s read the passage carefully to find the main idea and two supporting details.
The passage says:
- Bats are mammals.
- They have fur on their bodies like other mammals.
- They drink milk from their mothers.
- Baby bats are born live.
- Some people think bats are birds, but they’re not — they’re flying mammals!
- Fun fact: Bats are the only mammals that can fly.
Now, let’s look at the multiple choice for “What is the main idea?”
a. Bats are born live → This is true, but it’s just one detail.
b. Bats are mammals → This covers everything in the passage — fur, milk, live birth, even the fun fact about flying mammals.
c. Bats have fur on their bodies → Again, this is just one detail.
So the best answer for the main idea is
b. Bats are mammals — because all the other facts support that big idea.
Now, we need to write two supporting details from the passage that prove bats are mammals.
From the text:
1. They have fur on their bodies like other mammals.
2. They drink milk from their mothers.
(Also acceptable: Baby bats are born live — since most mammals give live birth.)
We’ll pick two clear ones.
Final Answer:
Main Idea: b. Bats are mammals.
Supporting Details:
1. Bats have fur on their bodies like other mammals.
2. Bats drink milk from their mothers.
