V/ READING

Read the three texts. For each question, choose the correct person.

Denise		A. There are many problems with pollution in the world, so it is hard to know where to start. For example, I read that the gases from cars in city centers damage the health of children. But the worst thing for me is plastic. We should stop using so much, because there is no way to recycle most of it. The waste goes into the land and doesn’t change, or it goes into rivers and oceans and harms or kills fish.
Noura		B. Did you know that 10% of the world’s population do not have clean water to drink? That’s terrible! Dirty water carries diseases, and drinking it every day is very bad, especially for children. Even in places with clean water, local people sometimes cannot get it, because it all goes to tourist hotels.
Monique		C. There is a problem which only started 20 or 30 years ago. At one time, people bought clothes and wore them for months or even years. Now, people buy cheap clothes in the latest fashion and only wear them two or three times. They throw them away, and they go into the trash in the ground. We cannot recycle most clothing at the moment.
