In an ideal world,people would not test medicines on animals. Such experiments are stressful and sometimes painful for animals,and expensive and timeconsuming for people. Yet animal experimentation is still needed to help bridge vast gaps in medical knowledge. That is why there are some 50 to 100 million animals used in research around the world each year. Europe,on the whole,has the world's most restrictive laws on animal experiments. Even so,its scientists use some 12 million animals a year,most of them mice and rats,for medical research. Official statistics show that just 1.1 million animals are used in research in America each year. But that is misleading. The American authorities do not think mice and rats are worth counting and,as these are the most common laboratory animals,the true figure is much higher. Japan and China have even less comprehensive data than America. Now Europe is reforming the rules governing animal experiments by restricting the number of animals used in labs. Alternatives to animal testing,such as using human tissue or computer models,are now strongly recommended. In addition,sharing all research results freely should help to reduce the number of animals for scientific use. At present,scientists often share only the results of successful experiments. If their findings do not fit the hypothesis being tested,the work never sees the light of day. This practice means wasting time,money,and animals' lives in endlessly repeating the failed experiments. Animal experimentation has taught humanity a great deal and saved countless lives. It needs to continue,even if that means animals sometimes suffer. Europe's new measures should eventually both reduce the number of animals used in experiments and improve the way in which scientific research is conducted. What is the main idea of this passage? A) The success of animal experiments should be ensured. B) A ban on the use of animals in the lab should be enforced. C) Greater efforts need to be taken to reduce the number of lab animals. D) Scientists should be required to share their research results with each other.

(Question)
I recently had dinner with someone who told me that one of his best friends had been killed in a private plane crash, and something happened at the memorial service that he'll never forget. He shared the story with me. At the memorial service, his friend's wife walked to the platform to speak to the gathering. She said a friend had asked her the best memory she had of their life together. At the moment, she had been too sad to answer, but she had thought about it since and wanted to answer the question. They were in their late forties when he died, and she began talking about a time in their life almost twenty years earlier. She had quit her job to obtain her master's degree, and her husband never hesitated in his support. He held down his own job and also did the cooking, cleaning, and other housework while she studied for her degree. One time they both stayed up all night. She was finishing her paper, and he was preparing for an important business meeting. That morning, she walked out of her study, leaned against the door by the stairs, looked at her husband downstairs and just thought about how much she loved him. She knew how important this meeting was to his future, and she was feeling guilty that she didn't even have time to make his breakfast. He took his briefcase and hurried out. She heard the garage door open and close, but much to her surprise, she heard it open again about thirty seconds later. From above, she watched her husband dash into the house and walk over to the forgotten coffee table. Marking the surface of it with his finger through the dust with the words "I love you", then he raced back to his car. The new widow then looked out at her audience and said, "John and I had a wonderful life together. We have been around the world several times. We've had everything money can buy...but nothing comes close to that moment." Hearing this, I was deeply moved. "Love makes life worthwhile." The woman mentioned an incident 20 years ago to show _ . A) how busy their life was B) how her husband loved her C) how they improved their life D) how hard her husband worked

Ques: Edward Wilson The Future of Life, . Edward Wilson is America's, if not the world's, leading naturalist. In The Future of Life, he takes us on a tour of the world's natural resources . How are they used? What has been lost? What remains and is it able to continue with the present speed of use? Wilson also points out the need to understand fully the biodiversity of our earth. Wilson begins with an open letter to the pioneer in environment protection, Henry David Thoreau. He compares today's Walden Pond with that of Thoreau's day. Wilson will use such comparisons for the rest of the book. The problem is clear: man has done great damage to his home over the years. Van the earth, with human help, be made to return to biodiversity levels that will be able to support us in the future? Biodiversity, Wilson argues, is the key to settling many problems the earth faces today. Even our agricultural crops can gain advantages from it. A mere hundred species are the basis of our food supply, of which but twenty carry the load. Wilson suggests changing this situation by looking into ten thousand species that could be made use of, which will be a way to reduce the clearing of the natural homes of plants and animals to enlarge farming areas. At the end of the book, Wilson discusses the importance of human values in considering the environment. If you are to continue to live on the earth, you may well read and act on the ideas in this book. Wilson suggests that one way to keep biodiversity is to _ . A) learn how to farm scientifically B) build homes for some dying species C) make it clear what to eat D) use more species for food
