— The blue one.
In a midsummer, Tom went on an outdoor trip with a (medicine) team from Britain. The purpose of the trip is to find out (who) ancestors the people in a temple were. First, they took a truck to the right position. Then they had a picnic. At night they were so sleepy, they tried to save energy. (prevent) cold, they wore coats instead of suits.
Just then, they heard a lot of noise, and they saw a wolf (run) after some rabbits. Then they saw a pink circle moving towards the wolf. After a short period, the wolf, rabbits and the circle disappeared. “There wasn't (somebody) else. The circle must be alien landing there. It's a great honor for us!” Tom said." Yes. I feel the trip is very valuable, though a little uneasy. These happenings must (express) more fully now. Wed better call the policemen," a friend added.
Later Tom received a call from a historian who was working in a laboratory. He explained the mystery. There wasn't an alien at all. It was rabbits attacking their enemy, the wolf. The circle was a rabbit (lead)and rabbits celebrating their victory. the same time, it was the wolfs burial for sure.
