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.

Input: Consider Input: Article: I have nothing to say about whether or not "A Day Without Immigrants " had a positive or negative effect on the question of how the federal government should deal with the huge population of undocumented illegal immigrants in this country. I'll leave that question to others. Regardless of how you feel about the event, one conclusion is obvious. Using the theme of "A Day Without" as a way to focus national attention on a particular subject is a great idea, and could serve as a method for increasing public consciousness about other issues that affect daily life in America. Here are my top three examples: "A Day Without Speeding." How hard could this be? If all drivers would strictly obey every posted speed limit on highways, downtown, on neighborhood streets, and in parking lots for one 24-hour cycle, the benefits would be huge. "A Day Without Losing Your Temper." A higher degree of difficulty here, and I know that from personal experience. When something goes wrong at home or on the job, there may be brief satisfaction in yelling or kicking the furniture, but bursting into anger usually has nothing to do with the approach to the heart of the matter. "A Day Without Having All The Answers." I would like to get a break from hearing anyone speak the phrase, "Here's what you're doing wrong." Right now the US is packed with citizens who believe they can point out the cause of every single problem in existence and then solve it in a moment. I believe they need to be quiet sometimes and use their ears instead of their voices. I wonder how would average Americans react to such a national pause? Would it be a day of reaction against anger, or joyful celebrations?
Answer: show public consciousness of some subjects could be raised

Output: The author uses his "top three examples" to _ .

Input: Consider Input: Article: Few, if any, instruments shape national culture more powerfully than the materials used in schools. Textbooks are not only among the first books most people meet; in many places they are, along with religious texts, almost the only books they have. A study in South Africa showed that fewer than half of pupils had access to more than ten books at home. In 2010 a study by Egypt's government found that, apart from school textbooks, 88% of Egyptian households read no books. The degree to which a government keeps control of the textbooks used in classrooms is a good guide to its commitment to ideological control. Where that desire is strong, governments are likely to produce the textbooks themselves or define carefully what goes into them. America's State Department employs people to keep an eye on other countries' textbooks, in an effort to understand better how their people think and what their governments want them to think. Other countries probably do the same. Textbooks have long been a source of worry. After the attacks on America on September 11th 2001, some in both America and Saudi Arabia, including officials, supposed that Saudi Arabia's curriculum of intolerance was responsible, at least in part, for the emergence of al-Qaeda . Sometimes the requirements of the state are more clearly seen in what textbooks leave out. The world has long criticized Japan for the way its textbooks whitewash the country's history, in particular dressing up Japanese war crimes. The "New History Textbook", for example, which was submitted for government approval in 2000, played down Japan's aggression in the Sino-Japanese war of 1894-95 and the occupation of China in the 1930s and 1940s, and avoided mention of the use of sex slaves by its armies or the rape of Nanjing. In America most of the disputes about textbooks are home-grown. Liberals worry that their children are being taught a nationalistic version of history that emphasizes the wonders of industrialization and plays down slavery and the killing of Indian tribes. By contrast, Conservatives complain about inadequate education of love for their country and too much secularism . In 2010 the Texas board of education managed to remove Thomas Jefferson, author of the Declaration of Independence, from the state's list of important revolutionary figures, apparently because of Jefferson's insistence on the separation of church and state. He was, however, swiftly restored. As long as textbooks are issued or approved by the state, they will remain a political issue. But as access to other textbooks is enjoyed more widely, some of the dominance they now enjoy will weaken.
Answer: to inform the readers of present practices of textbooks

Output: The author's purpose of writing this passage is_.

Input: Consider Input: Article: Scientists from England's Newcastle University have discovered that bacteria have the ability to detect smells, according to a study by the university on Sunday. The team of scientists, led by Dr. Reindert Nijland, discovered that bacteria can detect certain types of smell- producing chemicals, including ammonia that is produced by other bacteria. Once they sense the smells from other kinds of bacteria, the bacteria will gather together to form a colony and form a layer of slime in order to force the competitors out of their area. The response decreases as the distance between the two bacterial colonies increases. That slime, also known as biofilm, is one of the primary causes of infection on many medical implants . Biofilms also slow down ships and are believed to cost the marine industry millions of dollars annually. However, they can also be used to clean up spilled oil floating on the sea, as they grow strong on it. "This is the first evidence of a bacterial 'nose'able to detect potential competitors," Dr. Nijland said in the August 15 statement, which confirms that bacteria possess qualities similar to four of the five senses that humans enjoy (sight, hearing, touch, taste, and smell), the others being touch, taste, and sight. "The fact that bacteria formed slime when exposed to ammonia has important significance for understanding how biofilms are formed and how we might be able to use them to our advantage," he added. Their findings were published in Sunday's edition of biotechnology journal, and could change the way scientists look at how each of the senses developed over time. "It was thought for a long time that smell existed only in complex living creatures," Dr. Nijland said. "Now we see that bacteria are able to do the same, so the indication is that the ability may have developed even earlier."
Answer: can be used to benefit humans
Output: We learn from the text that biofilms _ .
