Read the following article and select the best answer. Article: The ozone layer is a thin layer of gas around the earth. It forms a special "blanket" around the planet. This "blanket" protects the earth from dangerous rays produced by the sun. Without the ozone layer, the earth's climate could warm to dangerous levels. This increase in temperature would threaten our survival. Scientists recently have discovered a hole in the ozone layer above the Antarctica. Now there is great concern that this warning has started, endangering all life on the earth. What has destroyed part of the ozone layer? Scientists do not know for sure. They suspect that our popular spray cans have played a part in the damage. Many spray cans contain dangerous gases. These gases might have destroyed the ozone layer fifteen miles above the earth's surface, The chemicals used in refrigerators and air conditioners may contribute to the problem, too. Many scientists believe that the destruction of the ozone layer is a serious problem for people everywhere. Global warming could change weather patterns around the world. Farmers and ranchers could find it more and more difficult to produce enough food for the earth's people. If more of the sun's dangerous rays reached the earth, there also could be an increase in skin cancers. Some skin cancers might cause people to die. Although some scientists do not believe there is a serious danger, obviously no one wants to take any chance on such a possibility. Can scientists repair the hole in the ozone layer? They really don't know the answer to that question. Can people do anything to save the ozone layer that the earth still has? Scientists stress the need to limit the use of spray cans and other items that contain the dangerous gases. This will not be an easy task. People all over the world use these items. Solving the problem certainly will require commitment and cooperation from everyone. Question: The following may do harm to the ozone layer EXCEPT _ . - spray cans - refrigerators - ranchers - air conditioners
ranchers

Read the following article and select the best answer. Article: Lilian Hanson, a college student, expects to graduate in about two years. What makes Mrs Hanson different from her classmates is her age -- 73 years. She has been studying at college, a few courses at a time, for 27 years. When Lilian Hanson graduated from high school, she went to the bank to borrow money for further education. The banker gave her no encouragement. He didn't think that a country girl should borrow money to go to college. He thought she should be at home doing work in the house or around the farm. So Lilian Hanson went home and raised a family of nine children instead of going to college. Mrs Hanson never forgot her dream of getting a higher education. When her children were grown, she tried again. She finds the hardest part of going back to school at her age is the sitting in class for long periods of time. Because she is not as flexible as she used to be, Mrs Hanson often gets up and walks around between classes to keep from getting stiff . At the beginning of a course in using the computer, the other students all stood and gave her a warm welcome when she introduced herself and explained why she was there and what her aims were. Question: Lilian wasn't able to go to college after graduation from high school because _ . - she wanted to teach herself - she got married - she had to look after her children - she hadn't enough money
she hadn't enough money
