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: Scientists think it will be possible to record people's dreams and then interpret them, according to a new report. They claim to have developed a system which allows them to record higher level brain activity. Dr Moran Cerf told the journal Nature: "We would like to read people's dreams." Previously the only way to access people's dreams is for psychologists to ask about them after the event and try to interpret them. Dr Cerf hopes to eventually compare people's memories of their dreams with an electronic visualization of their brain activity. He told the BBC: "There's no clear answer as to why humans dream. And one of the questions we would like to answer is when do we actually create this dream?" The scientist believes his latest research shows that certain neurons or individual brain cells are linked with specific objects or concepts. He found that a particular neuron lit up when a volunteer thought about Marilyn Monroe. If a database was built up identifying various neurons with concepts, objects and people it would allow them to "read the subject's minds", according to Dr Cerf. However, Dr Roderick Oner, a clinical psychologist and dream expert, said that this kind of visualisation would be of limited help when it came to interpreting the "complex dream narrative". In addition to get a detailed picture of individual neurons subjects had to have electrodes implanted deep in the brain using surgery. The Nature researchers used data from patients who had electrodes implanted to monitor and treat them for brain seizures . However, Dr Cerf said he hoped that it would be possible at a later stage to monitor people without invasive surgery. He said it would be "wonderful" to be able to read the minds of _ patients who are unable to communicate.
Answer: by linking certain neurons with specific objects or concept
Example Output: According to the passage, psychologists try to interpret people's dreams _ .

Example Input: Article: Making friends is a skill like most skills. It improves with practice. If you want to meet people and make friends, you must be willing to take some action. You must first go where there are people. You won't make friends staying home alone. Joining a club or a group, talking with those who like the same things as you do is much easier. Or join someone in some activity. Many people are nervous when talking to new people. After all meeting strangers means facing the unknown. And it's human nature to feel a bit uncomfortable about unknown. Most of our fears about dealing with new people comes from doubts about ourselves. We imagine other people are judging us, finding us too tall or too short, too this or too that. But don't forget that they must be feeling the same way. Try to accept yourself as you are, and try to put the other person at ease. You'll both feel more comfortable. Try to act self-confident even if you don't feel that way. When you enter a room full of strangers, such as a new classroom, walk tall and straight, look directly at other people and smile. If you see someone you'd like to speak to, say something. Don't wait for the other person to start a conversation. Just meeting someone new does not mean that you will make friends with that person--friendship is based on mutual liking and "give and take". It takes time and effort to develop.
Answer: Making friends
Example Output: The best topic of the passage may be _ .

Example Input: Article: Hundreds of Chinese officials are to be sacked or demoted for their part in a vaccine scandal that has added to discontent at poor oversight of food and drug safety, especially relating to children. Xinhua, the state news agency, said late on Wednesday that 357 officials are to face punishment, with 192 criminal cases already filed and 202 people detained after improperly stored or transported vaccines were sent to 59 health institutions. This is the latest in a string of food and drug safety scandals in a country where parents often import products for infants and babies from overseas to ensure quality. Many remember with fear the 2008 milk powder scandal, in which infant formula laced with melamine caused at least six deaths and 300,000 children to fall ill. Beijing last month made public an illegal operation in eastern Shandong province in which a hospital pharmacist and her daughter traded $88m in vaccines that may have been compromised because they were expired or improperly stored or transported. The China Food and Drug Administration said, however, that the vaccines posed no greater than the normal risk to patients. "We don't see that the vaccines' effectiveness has been reduced," added the health watchdog in a report. Nonetheless, health officials fear a backlash against Chinese-manufactured vaccines, which already have a reputation for being more dangerous than those made overseas. Wang Yuedan, deputy director of Peking University's immunology department, said the key to evaluating risks is to check whether package seals are broken or for pollution with micro-organisms. "The vaccines in the Shandong case don't have those problems," he said. Those vaccines had been subject to higher than normal temperatures that could have lowered their effectiveness and reduced their protective value. But the official investigation showed the vaccines "are still effective", he said. Beijing, which publicized the affair almost a year after it was exposed, and several years after it started, appeared eager to show commitment to crack down on abuses by announcing the action, political analysts said. The CFDA said a system was being set up to track vaccines from production to use. The World Health Organization warned the scandal could endanger China's public health gains if parents become distrustful of vaccines. It also expressed confidence in Chinese vaccines, saying public immunization campaigns had erased polio and sharply reduced cases of hepatitis B and measles.
Answer: were still effective
Example Output:
According to Wang Yuedan's opinion, the vaccines in Shandong _ .
