Question 1: What is the poem all about?

Options:
A. The sky
B. A flower
C. A butterfly

✔ Correct Answer: C. A butterfly

Explanation:
The entire poem focuses on a butterfly — its movement, flight, and departure. While the sky is mentioned, it’s just the background where the butterfly flies. There is no mention of a flower. So, the main subject is clearly a butterfly.

Question 2: Which sentence tells the main idea?

Options:
A. It is flying in the sky.
B. It will come back again.
C. A butterfly goes by.
D. I see it fly away.

✔ Correct Answer: C. A butterfly goes by.

Explanation:
The main idea is the most important point of the poem. While other sentences give details (like flying or leaving), the central idea is that a butterfly passes by. This sentence introduces the main subject and event. The rest are supporting details:
- "It flies up to the sky" – describes what it does.
- "I see it fly away" – observer's perspective.
- "Come back another day" – hopeful ending, but not the core idea.

So, C best captures the overall theme.

Question 3: What is the best name for the poem?

Options:
A. The Butterfly
B. Blue Sky
C. Pretty Flower

✔ Correct Answer: A. The Butterfly

Explanation:
The poem is centered around the butterfly. Although the sky is mentioned, it’s not the focus. There’s no mention of a flower at all. Therefore, "The Butterfly" is the most accurate and fitting title.

✔ Final Answers:

1. C. A butterfly
2. C. A butterfly goes by.
3. A. The Butterfly

This exercise teaches identifying the main idea (what the passage is mostly about) and supporting details (extra information that helps explain the main idea). Great job! 🦋
