TASK DEFINITION: In this task, you're given an article and an answer. Your task is to generate the fill-in-the-blank question for this answer based on the given article. The blanks are always at the end of the question, and can be filled with more than one word or phrase.
PROBLEM: Article: This is a dangerous world we live in.The number of murders goes up every year, people are dying of cancer, more people contract HIV, more teens are using drugs, etc.You know this because you have heard all the statistics on the news and in the paper. But do you really have an accurate idea what they mean? The numbers are growing up, but how do they compare to the growth in population? Are more cases of these diseases being reported because of better testing techniques, or are the diseases more common? The fact is that without knowing the background statistics mean very little. This growing trend of reporting only part of the information is becoming dangerous.For example, several years ago a high school student reported the dangers of the chemical known as dihydrogen monoxide.This chemical, found in most cancerous tumors , is often found in the blood of people drunk on alcohol, and causes complete physical and mental dependence for those who take the chemical even once.After reading his report, more than 75% of his Advanced Placement Chemistry class voted to forbid this dangerous chemical! Every one of the above statements is true, yet this chemical is necessary to all life on earth.The students made the mistake because they voted knowing only a few statements and statistics, rather than the chemical's full background. The point of this article is that one should be aware of what is and is not being said.When one finds a new fact or number, one should try to consider other important information before forming an opinion with only half-truths.Always remember that the author is trying to convince you of his or her own view, and will leave out information that is different to his view.For example, look again at the statistics that suggest skiing is safe.Only 32 people may die each year when skiing, while 897 die from lightning strikes, but which is really the most dangerous? If you think about it, you realize far fewer people go skiing each year than the number of people who are in danger of a lightning strike.When you think about it, skiing is more dangerous than you might at first think when looking at statistics.If we teenagers are to be left in this world, we had better be able to think critically, and form our own views, rather than be easily persuaded by another's.To be warned is to be prepared. 
 Answer: readers are not able to analyze so much information at once.

SOLUTION: Relative information is often left out because  _  .

PROBLEM: Article: Humans are well-equipped for life on Earth. But in space, it is different. Low or _ changes how the blood flows and causes motion sickness, muscle loss and tiredness. Weightlessness can also cause bone loss. But scientists are experimenting with little worms to better understand how space travel affects astronauts. The millimeter-long worm is called C. elegans. The see-through worm is often used in medical studies because its life is only about two weeks long. Seventy percent of its DNA is the same as human DNA. Sabanayagam is a scientist, who built a micro-gravity simulator to test how C. elegans would perform in the actual zero gravity of space. Scientists put the worms into the simiulator full of water. After a week they take out the worms. They look for changes in the worms' epigenome,which are chemical markers that tell the DNA in the cells how to perform. The epigenome can be changed by the environment. And those changes pass from one generation of worms to the next. "When the worms are in a liquid environment, some epigenomic marks remain even when we take the animal out of the liquid environment and put it back into normal ground conditions. So its offspring keeps this epigenomic memory of the parents' liquid environment or microgravity environment." The information the scientists have gathered suggests that the epigenomic marks appear during the early part of a worm's life. Mr. Sabanayagam says he thinks scientists can find genes in the human similar to those in the worms that responded to microgravity and scientists could possibly observe those genes closely when astronauts travel in space. Sabanayagam expects C. elegans to visit the International Space Station within two years. He says he hopes information gathered from the worm studies can be used to develop simple, low-cost and quick tests to measure an astronaut's health. 
 Answer: has a short life period

SOLUTION: From the passage we can know C. elegans   _  .

PROBLEM: Article: Consumers are being confused and misled by the hodge-podge  of environmental claims made by household products, according to a "green labeling" study published by Consumers International Friday. Among the report's more unacceptalbe findings - a German fertilizer described itself as "earthworm friendly"; a brand of flour said it was "non-polluting" and a British toilet paper claimed to be "environmentally friendlier". The study was written and researched by Britain's National Consumer Council (NCC) for lobby group Consumers International. It was funded by the German and Dutch governments and the European Commission. "While many good and useful claims are being made, it is clear that there is a long way to go in ensuring shoppers are adequately informed about the environmental impacts they buy," said Consumers International director, Anna Fielder. The 10-country study surveyed product packaging in Britain, Western Europe, Scandinavia and the United States. It found that products sold in Germany and the United Kingdom made the most environmental claims on average. The report focused on claims made by specific products, such as detergent  , insect sprays and some garden products. It did not test claims, but compared them to labeling guidelines set by the International Standards Organization (ISO) in September, 1999. Researchers documented claims of environmental friendliness made by about 2,000 products and found many too vague or too misleading to meet ISO standards. "Many products had specially designed labels to make them seem environmentally friendly, but in fact many of these symbols mean nothing," said report researcher Philip Page. "Laundry detergents made the most number of claims with 158. Household cleaners were second with 145 separate claims, while paints were third on our list with 73. The high numbers show how confusing it must be for consumers to sort the true from the misleading," he said. The ISO labeling standards ban vague or misleading claims on product packaging, because terms such as "environmentally friendly" and "non-polluting" cannot be verified. "What we are now pushing for is to have multinational corporations meet the standards set by the ISO," said Page. 
 Answer: the claims made by products are often unclear and deceiving

SOLUTION:
According to the passage, the NCC found it unacceptable that   _  .
