Read the following passage and mark the letter A, B, C, or D to indicate the correct answer
to each of the questions.
Mount Everest is the highest mountain in the world. It is also the highest trash pile in the
world. About 400 people try to reach the top every year. This many climbers means a lot of
trash. It is very dangerous to climb Mt. Everest. The air is very thin and cold. Most people
carry oxygen bottles; they could die without them. When the oxygen bottles are empty,
people throw them on the ground. When strong winds rip their tents, people leave them
behind. They don't have enough energy to go down the mountain safely. Trash is a terrible
problem. Since people first began to climb Mt. Everest, they have left 50,000kilos of trash
on the mountain. Several groups have climbed the mountain just to pick up the trash. When
people plan to climb the mountain, they have to plan to take away their trash.
