- about two-thirds of the waste can pollute the environment

Read the following article and answer the question. Article: Chemicals used for industrial processes often create dangerous forms of waste. The amount of these chemicals has risen heavily in the past few years, as more areas of the world industrialize and new products are produced. Over 80,000 different chemicals are used in industries world wide. Around the world hundreds of millions of tons of harmful waste are produced each year. Often, it is difficult and expensive to get rid of these chemicals or to store them in a way that does not endanger human life and the environment. Every year, major health problems result from harmful waste. Sadly, it is often when someone has died or, become seriously ill that governments will take action and reduce levels of dumped harmful waste. In 1989, a school inprefix = st1 /New Jerseyhad to be closed because students there had suffered too much exposure to chromium. It was later learned that large amounts of chromium had been dumped nearby and blown over to the school area. Research has been done to provide information on the effects of every chemical. Because waste chemicals often mix together, it will also be necessary to learn how the combinations of these chemicals affect human health. Some governments have realized how serous the problem is and are making laws to get rid of harmful waste. They are also trying to limit the amount of waste industries are allowed to produce. Not only governments but the public as well must form part of the solution. They can choose not to buy those products which require the production of harmful waste, attempt to affect policymakers, and produce less harmful waste themselves. Many scientists think that waste production can be cut. The waste can be reduced by at least one-third using existing technologies and methods. Question: From the text we know that _ . Answer:
****
A: Some governments don't realize how serious the problems are until people suffer a lot from harmful waste

Problem:OPTIONS:
- He was new to the class
- He was tired of literature
- He had an attention disorder
- He wanted to take the task home

Read the following article and answer the question. Article: At thirteen, I was diagnosed with kind of attention disorder. It made school difficult for me. When everyone else in the class was focusing on tasks, I could not. In my first literature class, Mrs. Smith asked us to read a story and then write on it, all within 45 minutes. I raised my hand right away and said, "Mrs. Smith, you see, the doctor said I have attention problems. I might not be able to do it." She glanced down at me through her glasses, "you are no different from your classmates, young man." I tried, but I didn't finish the reading when the bell rang. I had to take it home. In the quietness of my bedroom, the story suddenly all became clear to me. It was about a blind person, Louis Braille. He lived in a time when the blind couldn't get much education. But Louis didn't give up. Instead, he invented a reading system of raised dots , which opened up a whole new world of knowledge to the blind. Wasn't I the "blind" in my class, being made to learn like the "sighted" students? My thoughts spilled out and my pen started to dance. I completed the task within 40 minutes. Indeed, I was no different from others; I just needed a quieter place. If Louis could find his way out of his problems, why should I ever give up? I didn't expect anything when I handed in my paper to Mrs. Smith, so it was quite a surprise when it came back to me the next day with an "A" on it. At the bottom of the paper were these words: " See what you can do when you keep trying?" Question: The author didn't finish the reading in class because _ . Answer:

Read the following article and answer the question. Article: Your teenage daughter is supposed to be doing homework, but you catch her chatting online. She tells you that she's talking about the math test tomorrow. Before your eyes start rolling, listen up: teens are using social networking sites for more than just gossip, according to a new study by the National School Boards Association. The students who took part in the online survey, aged 9 to 17, said they spent almost as much time on social networking online as they did watching television. And it is what these kids are talking about online that is causing such a cheer: education. Of the students who took part in the study 60 percent reported that some of the most popular social networking topics were college planning, learning outside of school, careers, and schoolwork. They also reported posting writing and art projects that might have nothing to do with schoolwork. Ann Flynn, director of education technology for the National School Boards Association, says social networking tools into educational is the way forward. Flynn says a school in Cleveland, Ohio is posting students' book reports on a blog for students of their own ages, parents and other teachers to read and comment on. "If someone reacts other than the teacher, a child is much more likely to take an assignment seriously," Flynn says. Not only students but also parents can benefit. Now parents can go online and know what the class is doing. So, next time your child says her blog is educational, get curious, sit down and check out the blog with her. You might just learn something new yourself. Question: Why can parents benefit from social networking sites? Answer:
****
A:
Because parents can know their children's learning at school.
