351 Gardener Street Los Angeles, CA90031 September 12 Relex Company 37 Pearl Street Clifton, NJ07013 Dear Sir or Madam: A year ago I bought a Relex camera second hand. It's a SW 705 model, and it's about five years old. Here's my problem: The light metre was fine when I bought the camera, but now it isn't working and my pictures are coming out too dark. I checked the batteries, and they are still good. I took the camera to some repair shops, but they said they couldn't repair it because the model is too old and they don't have the necessary part. Do you have the parts for this model in stock? If so, could I send you the camera for repairs? How much would the repairs cost? I'm going to buy your new SW800 model in about six months, but I would still like to fix this old one. Thank you very much. Sincerely yours Sarah H, McDaniel When Sarah got the camera, _ . A) it worked very well B) it didn't have any batteries C) the light meter doesn't work well D) it didn't take good photos

DNA is the whole "map" of the human body. It is something that all human have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own. People have been trying to understand the human body for a long time. In 1860, Mr. Mendel discovered why we look the same as other people in our family. It is because of small things called "genes" in our body. In 1953, two scientists, Watson and Crick, found out that those small parts are really messages. They're written in the DNA with a special language. In 1961, another two scientists found the first "word" that they could understand in that language. It shows how DNA tells the cell to build its parts. So far, scientists have found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one "word" means, we can help to save people from several illnesses. So the more we understand, the more doctors will be able to do. Most people hope that this will help to make better medicine and help sick people. Other people worry that when we learn more "words" and and find out more information, we will use it in the wrong way, just to make people more attractive, or stop sick people getting jobs. When did Mr. Mendel discover why we look the same as other people in our family? A) In 2000 B) In 1961. C) In 1953 D) In 1860
