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.

Example Input: Article: A green house is a building made of glass which is used for keeping warm when the outside temperature is low. In a similar way there are several gases in the atmosphere (mixture of gases that surround the earth) which trap the heat produced by the sun and prevent it from escaping. These gases are known as "greenhouse gases". And the way in which they trap heat in the atmosphere is called the "greenhouse effect". This is not simply air pollution. Most of the main greenhouse gases exist naturally in small amounts in our atmosphere, and without them the earth would be 30 degrees colder and human life would not exist. In other words, the greenhouse effect is a natural course which is to some degree helpful to us. The problem is that in the last century and a half, we have been putting too many of these gases into the earth's atmosphere by burning large quantities of coal and oil and by cutting down forest. The rapid increase in greenhouse gases is making the world warmer. The world's temperature has already gone up by half a degree this century, and the sea level has risen by 10 centimetres. If the amount of carbon dioxide in the atmosphere doubles, there will probably be a rise in the earth's temperature of between I and 4degC;. This may seem a small increase, but it would be enough to cause major changes in geography and agriculture. Large areas of the world would be flooded, and some areas would become dry and unable to produce crops. It is important, too, to consider that there may be a delay of about 30 years in the greenhouse effect. This means that we are probably experiencing only now the effect of the gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased.
Answer: a natural course that is to a certain degree useful to us
Example Output: According to the passage, we can know "greenhouse effect" means _ .

Example Input: Article: For the first time in modem history, less than half of theprefix = st1 /U.S.adult population now reads literature, according to a recent survey. Reading at Risk: A Survey of Literary Reading inAmericapresents a detailed review of the decline of reading's role in the nation's culture. Readingat Risk is a survey of national fashion in adult literary reading. The data source for Reading at Risk is as reliable and objective as any such survey can be. The key results of the survey are presented in the "Summary", but the report can be further explained as: literary reading in Americais not only declining rapidly among all groups, but the rate of decline has been speeded up, especially among the young.Readingat Risk merely shows a great _ that most Americans have already noted - our society's great turn to electronic media for entertainment and information. Reading a book requires a degree of active attention and devotion. Indeed, reading itself is a progressive skill that depends on years of education and practice. On the contrary, most electronic media such as television, recordings, and radio make fewer demands on their audiences, and indeed often require no more than passive participation. While oral culture has a rich reality and electronic media offer the considerable advantages of variety, print culture affords irreplaceable forms of focused attention and thought that make various communications and views possible. The decline in reading, therefore, equals a larger retreat from participation in public and cultural life. What is to be done? There is surely no single solution to the present problem, just as there is no single cause. The important thing now is to understand thatAmericacan no longer take active and devoted reading for granted. Readingis not a timeless, common ability. As more Americans lose this ability, our nation becomes less informed, active, and independent minded. These are not qualities that a free, inventive, or productive society can afford to lose.
Answer: review that less than half of the population now reads literature
Example Output: The main purpose of the survey is to _ .

Example Input: Article: The loss of a job can have a very serious impact on the individual. The immediate effect, of course, is a sharp drop in income. Unemployment benefits typically offer less than half the individual's previous earnings, and many people are not even entitled to these benefits-for example, the self-employed, recent graduates who have not held a steady job in the previous year, and people who have been unemployed for a long period. The economic pressure on the jobless is very severe, particularly for those who have young children or long-term commitments for expenses for houses and education. But the effects of unemployment are not merely financial; they are also social and psychological. As one out-of-work teacher puts it: "It's difficult when you strip away all the things that supposedly hold you together in terms of an identity. Your work, your money, whatever is power to you, whatever is responsibility, whatever means freedom and choice." I had to ask myself, "Who am I now? What will I do now?" All too often, long-term unemployment may thrust the individual into boredom, despair, ill-temper, and perhaps, conflict with other family members. Even those who keep their jobs are affected by rates of unemployment, for they begin to fear for own future. Lacking the confidence that workers have in times of full employment, they negotiate less aggressively for improvements in pay or working conditions, for they and the employers know that if they do not like the job as it is, others will gladly take it. Unemployment is always accompanied, in fact, by underemployment-the situation in which people are working either for extremely low wages or at jobs below their level of skill.
Answer: people who have been unemployed for a short period
Example Output:
It can be inferred from the passage that unemployment benefits are given to _ .
