input question: Write a multi-choice question for the following article: Article: In 2013, a report from The Nero England Journal of Medicine showed that increased body weight is related to the death rate for all cancers. This is based on a study involving about 900,000 people, spanning many years. The study, started in 1992 by the American Cancer Society, included men and women from all 50 states. The youngest participants were 30 years old, and the '8verage age was 57. By December 2008, 24% of the participants had died, just a quarter of them from cancers. In analyzing the results, researchers attempted to take account of such potential factors as smoking drinking alcohol, taking aspirin and a wide variety of other factors that might otherwise affect the results. The results are clear the more you weigh, the greater your risk of dying of cancer will be (up to 52% higher for men and 62% for women). In men as well as women, the only cancers that did not have a strong connection with weight were lung cancer and-brain cancer. For women, the strongest correlation with weight was uterine cancer ,which is 6.5 times higher for women with a BMI(Body Mass Index)of 40 or more. For men, it was liver cancer, which is 4.5 times higher in most obese men. Smokers tend to be more successful in keeping weight off than non-smokers ,slightly reducing the risk ,But many of them don't have good lungs .Thus ,in another way ,they also face risks. As for why extra weight leads to excess cancer death rate ,there's no clear agreement .But the decrease in vitamin D in obese people seems a likely factor .Vitamin D is known to have a role in preventing cancer .Also, there is a simple fact that obesity makes the management of cancer more difficult .Although for now there is no simple answer to why obesity increases a person's cancer risk ,all we know for certain is that the risk is real.???

Problem: Given the question: Write a multi-choice question for the following article: Article: 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. Can 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 as well read and act on the ideas in this book.
