• Read the passage and choose the correct answer:
  Last year I went to Nepal for three months to work in a hospital. I think it's important to see as much of a country as you can, but it is difficult to travel around Nepal. The hospital let me have a few days’ holiday, so I decided to go into the jungle and I asked a Nepalese guide, Kamal Rai, to go with me.
  We started preparing for the trip at six in the morning, and left camp with two elephants carrying our equipment. It was hot but Kamal made me wear shoes and trousers to protect me from snakes. In the jungle there was a lot of wildlife, but we were trying to find big cats, especially tigers. We climbed onto the elephants' backs to get better view, but it is unusual to find tigers in the afternoon because they sleep in the heat of the day.
  Then, in the distance, we saw a tiger, and Kamal told me to be very quiet. We crept nearer and found a dead deer, still bleeding. This was the tiger's lunch! Suddenly I started to feel very frightened.
  We heard the tiger a second before we saw it. It jumped out like a flash of lightning, five hundred kilos plus and four meters long. I looked into its eyes and face, and saw right down the animal's throat. It grabbed Kamal's leg between its teeth, but I managed to pull Kamal away. One of our elephants ran at the tiger and made it go back into the grass, so we quickly escaped to let the tiger eat its lunch. That night it was impossible to sleep!
