Passage:
"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 that bats are birds, but they are not. Bats are flying mammals!"
---
Task 1: What is the main idea?
Main Idea: The main idea is the central point or message of the passage.
Looking at the passage:
- It starts by stating "Bats are mammals."
- Then it gives several facts to support that (fur, drink milk, born live).
- It also clarifies a common misconception: "Some people think bats are birds, but they are not."
- Ends with reinforcing: "Bats are flying mammals!"
So, the
main idea is clearly that
bats are mammals, not birds.
Now, let’s look at the choices:
a. Bats are born live.
b. Bats are mammals.
c. Bats have fur on their bodies.
✔ The best answer is:
b. Bats are mammals.
This is the overall main idea that all the details support.
---
Task 2: Write two supporting details.
Supporting details are facts that help prove or explain the main idea.
From the passage, we can pick two key details:
1.
They have fur on their bodies like other mammals.
→ This supports that bats are mammals (since fur is a mammal trait).
2.
They drink milk from their mothers.
→ Another key trait of mammals.
Other possible answers:
- Baby bats are born live.
- Bats are flying mammals.
But the two most direct and clear supporting details are:
1. Bats have fur on their bodies.
2. Bats drink milk from their mothers.
---
✔ Final Answers:
Main Idea:
b. Bats are mammals.
Two Supporting Details:
1. Bats have fur on their bodies.
2. Bats drink milk from their mothers.

📝 Explanation:
The passage is structured to teach that although bats can fly (like birds), they are actually mammals because they have traits such as fur, give birth to live young, and nurse their babies with milk. The main idea is the big takeaway — that bats are mammals — and the supporting details provide evidence for this claim.
