Answer:
The correct answer is The kids realize that the rain is less enjoyable than the sun.
Explanation:
It seems that the kids haven't seen the Sun in a very long time, years even. They are living underground on Venus and they have been for years. So in this moment, they finally see the Sun and all run outside to play and have fun and soak in the warmth after such a long time.
However, their happiness doesn't last long as it starts pouring rain and they have to go back to the underground house, understanding they will have to wait another seven years for the Sun to appear again.
Here is the entire excerpt:
A few cold drops fell on their noses and their cheeks and their mouths. The sun faded behind a stir of mist. A wind blew cool around them. They turned and started to walk back toward the underground house, their hands at their sides, their smiles vanishing away.
