Read the text and write T for True, F for False or NM for Not Mentioned.

A few weeks ago I was walking by the river with my friend, Jack, when suddenly the wind started blowing really hard and black clouds gathered in the sky. Minutes later a storm broke out. We came across an old building and decided to go inside for protection. We were looking around when, all of a sudden, we fell down into the basement. We couldn't believe it! The floor had collapsed. I wasn't hurt badly but Jack's leg was really hurting him. Worst of all, there was no way we could move around with all the rubble. We shouted for help, but there was no answer. We were terrified. After a few hours, it was raining even harder and, before long, water was coming down into the basement. I then realised that the river had flooded! I panicked. I was exhausted but I continued shouting until finally I heard a voice. Then I fainted. The next thing I knew, a rescue team was pulling me out of the rubble. We were very lucky because as soon as we got out of there, the whole building collapsed.

1. It had started raining by the time the boys went into the building.
2. The boys didn't want to enter the building because it looked dangerous, but they had to.
3. They couldn't get out of the building because they were injured.
4. The river had flooded by the time they got out of the building.
5. The writer fainted when he saw the rescue team.
