B
Alex and Nick decided to go camping in the mountains.
They took with them all the things they would need to go camping—warm clothes, food and a tent.
They went up to the mountains and found a perfect place to put up their tent. After that, they decided to walk around to see more of the mountains.
After a long walk, they went back to their camp, built a fire and cooked dinner. Soon, it was time to go to sleep.
In the middle of the night, Nick woke Alex up and said, “Look up at the sky. What do you see?”
Alex answered, “I see millions of stars.”
Nick said, “That’s right. What does that mean(意味着) to you?”
Alex said, “Well, if there are so many stars out there, that means there might also be a planet just like the planet we live on. And if that’s true, then there could be life on one of those planets. That’s kind of exciting!”
Nick said, “You are wrong. It means that someone has stolen our tent!”
