Let’s go through each question one at a time, using the poem to find the right answers.

Poem:

> A butterfly goes by.
> It flies up to the sky.
> I see it fly away.
> Come back another day.

Question 1: What is the poem all about?

We look at what the poem talks about most. The first line says “A butterfly goes by.” Then it talks about where it flies and what the speaker sees — but everything centers on the butterfly. The sky is mentioned, but only as where the butterfly flies. There’s no mention of a flower. So the main subject is the butterfly.

✔ Correct answer: C. A butterfly

Question 2: Which sentence tells the main idea?

The main idea is the big point — what the whole poem is mostly saying. Let’s look at the options:

- A. “It is flying in the sky.” → This is just one detail.
- B. “It will come back again.” → That’s from the last line, but it’s not the main focus.
- C. “A butterfly goes by.” → This is the very first line, and everything else builds off this. It introduces the butterfly and starts the story.
- D. “I see it fly away.” → Again, a detail, not the main idea.

The best choice is the one that sets up the whole poem — the butterfly appearing.

✔ Correct answer: C. A butterfly goes by.

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

We want a title that matches what the poem is mainly about. We already know it’s about a butterfly. “Blue Sky” is too focused on one detail. “Pretty Flower” isn’t even in the poem! “The Butterfly” fits perfectly — simple and directly about the main character of the poem.

✔ Correct answer: A. The Butterfly
