Question

we spend the whole day exploring.
we get moon rocks to bring back.
the problem comes when we reboard
and weigh each persons pack.

zacks pack is far too heavy,
so our ship cant take off yet.
i say ill leave my rocks behind—
with rocks at home, im more than set.

zack says he needs the moon rocks
to give to his family as gifts.
he keeps telling me how happy he is
as our spaceship finally lifts.

what is the main theme of the poem?

thoughtful gifts are great for family.

a small act of kindness can mean a lot to someone.

its important to follow rules to stay safe.

you can learn a lot by traveling to new places.

Explanation:

1. Analyze the first option: The poem is not mainly about gifts for family, as the key event is the speaker's act of leaving their rocks to help the ship take off, not the nature of Zack's gifts.
2. Analyze the second option: The speaker leaves their moon rocks so the ship can take off, and Zack is happy. This small act of kindness (giving up rocks) has a significant positive impact on Zack, matching the theme.
3. Analyze the third option: There's no mention of rules for safety in the poem; the issue is pack weight, not rule - following.
4. Analyze the fourth option: The poem is not about learning from travel, but about a kind act during a space exploration - related situation.

Answer:

B. A small act of kindness can mean a lot to someone.
