Please answer this: Write a multi-choice question for the following article: Article: How can you find out what is going on inside a person's body without opening the patient's body up? Regular X rays can show a lot. CAT scans can show even more. They can give a complete view of body organs. What is a CAT scan? CAT stands for a kind of machine. It is a special X-ray machine that gets a 360-degree picture of a small area of a patient's body. Doctors use X rays to study and determine diseases and injuries within the body, X rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed. A CAT scanner, however, uses a group of X rays to give a cross-sectional view of a specific part of the body. A fine group of X rays is scanned across the body and around the patient from many different directions. A computer studies the information from each direction and produces a clear cross-sectional picture on a screen. This picture is then photographed for later use. Several cross sections, taken one after another, can give clear "photos" of the entire body or of any body organs. The latest CAT scanners can even give clear pictures of active, moving organs, just as a fast-action camera can "stop the action", giving clear pictures of what appears unclear to the eye. And because of the 360-degree pictures, CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient. Frequent appearance before X rays can cause skin burns, cancer or other damage to the body. Yet CAT scans actually don't cause the patient to more radiation than regular X rays do. CAT scans can also be done without getting something harmful into the patient, so they are less risky than regular X rays. CAT scans provide exact, detailed information. They can quickly find such a thing as bleeding inside the brain. They are helping to save lives.

Problem: Write a multi-choice question for the following article: Article: An absolute description of the threat hanging over the world's mammals, reptiles, amphibians(, , ) and other life forms has been published by the well-known scientific journal, Nature. A special analysis carried out by the journal indicates that an astonishing 41% of all amphibians on the planet now face extinction while 26% of mammal species and 13% of birds are similarly threatened. Many species are already critically endangered and lose to extinction, including the Sumatran elephant, Amur leopard and mountain gorilla. But also in danger of vanishing for the wild, it now appears, are animals that are currently rated as merely being endangered. In each case, the finger of blame points directly at human activites The continuing spread of agriculture is destroying million of hectares of wild habitats every year, leaving animals without homes, while the introduction of newly-come species, often helped by humans, is also damaging native populations. At the same time, pollution and overfishing are destroying ocean ecosystems. "Habitat destruction, pollution or overfishing either skill off wild creatures and plants or leaves them badly weakened," said Derek Tittensor, an ocean ecologist at the World Conservation Monitoring Centre in Cambridge. "The trouble is that in coming decades, the additional threat of worsening climate change will become more and more common and could then kill off these survivors." The problem, according to Nature, is worsened because of the huge gaps in scientists knowledge about the planet's biodiversity. Evaluations of the total number of species of animals and plants alive vary from 2 million to 50 million. In addition, evaluations of current rates of species' disappearances vary from 500 to 36, 000 a year. "That is the real problem we face," added Tittensor. "The scale of uncertainty is huge." In the end, however, the data indicate that the world is heading cruelty towards a mass extinction-which is defined as one involving a loss of 75% of species or more. This could arrive in less...

A: Question: What does "This" in the last sentence refer to _ ?Options:A mass extinctionB extinction ratesC extinction timeD 75% of species or moreAnswer:A

Q: Write a multi-choice question for the following article: Article: The Japanese government has launched a campaign encouraging people to go to bed and get up extra early in order to reduce household carbon dioxide emissions . The Morning Challenge campaign, launched by the Environment Ministry, is based on the belief that changing late night electricity for an extra hour of morning sunlight could greatly cut the nation's _ . A typical family can reduce its carbon dioxide footprint by 85kg a year if everyone goes to bed and gets up one hour earlier, according to the campaign. The amount of carbon dioxide emissions that might be saved from going to bed an hour earlier equals 20% of annual emissions from household lights. "Many Japanese people waste electrical power at night-time, for example, by watching TV until very late," a ministry spokesperson told The Daily Telegraph. "But going to bed early and getting up early can avoid wasting electrical power which causes carbon dioxide emissions. If people change their lifestyle, we can save energy and reduce emissions." The campaign also suggests that people take advantage of an extra hour of morning sunlight by improving their lifestyle in general by running, doing yoga and eating a nutritious breakfast. It is the latest initiative fighting climate change by the Japanese Environment Ministry, which is faced with the challenge of reducing carbon dioxide emissions by 25% from the level of 1990 within the next decade. It was the same government department that launched the Cool Biz campaign five years ago, which encourages workers to wear short-sleeved shirts and offices not to turn air conditioner lower than 28 degrees Celsius during summer.
A:
Question: The Morning Challenge campaign is aimed at _ .Options:A saving electricity and cost in JapanB reducing carbon dioxide emission at homeC improving Japanese citizens' lifestyleD making full use of morning sunlightAnswer:B
