Read the following article and answer the question. Article: Hello, I'm Peter in the second grade. Now I have one thing to say: It's not easy being a kid. Being a kid might look like fun, but sometimes it's not fun at all. Yesterday I was playing outside with my friend. We were having a good time. But suddenly, my mother said, "Peter, it's time to come inside now. It's getting dark." When you're an adult, no one can tell you what to do or when to do it. When you are a kid, you have to get up early in the morning and go to school. At school, you have to study math, English, science and history. After school, you have to do your homework. When you are an adult, you do not have to go to school and you never have homework to do. When you are a kid, the older kids sometimes _ you. When I was walking home from school on Monday, Tom and Steve bothered me. Steve took my schoolbag and put it in a tree. It made me very mad. When you are an adult, no one can pick on you. When you are a kid, you have to go to bed early. On school nights, my mom asks me to go to bed at 9:00 pm. But I do have parents who love me, which is really great. So I think I like being a kid, even though it's not easy being a kid. ,. Question: As a kid you do the following things EXCEPT _ . Answer:
OPTIONS:
- go to school
- do your homework
- get up early and go to bed early
- go anywhere without telling anyone

Read the following article and answer the question. Article: Do you or someone you know use a mobile phone? In today's world, many people use a mobile phone especially businessmen and businesswomen. These people are an important part of the business world and help our economies develop. In fact in some countries even children and the elderly use mobile phones to keep in touch with family and friends. We know how useful it is to have a mobile phone, but do we know how safe these phones are? Some scientists say that mobile phones could be a risk to our health. So, money is being given to scientific research to find out if mobile phones may be harmful in any way. What does the future look like? Is a hands - free phone the answer?

Some reports say that hands - free sets have 95% less radiation exposure, while other reports say that hands - free sets expose you to more radiation. Governments and the mobile phone industry are researching the effects, including: * the effects of radio waves on blood pressure and the brain, such as the abilities to concentrate, remember and learn the connections between mobile phone use and brain cancer long - term effects of mobile phone use, looking at health histories of people who have used mobiles since the 1980s. They will be looking at both current mobile phones and the new generation of 4G phones. The results from these studies will help us understand more about the world beyond mobile communications.
