In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.

Article: Did you know that there are actually people who have paid for a flight to the moon? In the future, there will be a lot more opportunities to travel to faraway places than now... perhaps even as far as the moon. As people adventure further and further away and as planes, trains, cars, and rocket ships become faster, is it safer to have these vehicles controlled by humans or by computers? While many flights by plane are controlled automatically by machines, most people today wouldn't let their car drive itself. That's because currently the autopilot function on your car can only keep it on the same course you are travelling on. It won't turn the car right or left. It won't stop if an animal jumps in the way. However, cars today can sense when something is too close and warn the driver with flashing lights and alarms. Many cars also have GPS(global positioning systems) that tell drivers which road to take and when to turn. These systems, unlike human drivers, never get lost. In the future, it is easy to believe that your car will be better able to drive itself with the aid of computers that can determine the position of your car and the speed it should travel at. In addition to computers being 'smarter' than people regarding the best way to go or knowing how close another vehicle is, computers don't get sick, tired, or angry. This means they won't make the same mistakes that people make when they are not having a good day. While responding with emotion is a good thing when choosing the best way to deal with a friend's personal problem, it may not be such a good thing when deciding what to do at the wheel of a fast-moving vehicle. So what are the disadvantages of autopilot systems? Maybe one disadvantage is that a small computer problem could cause a serious accident. It could also be argued that in unexpected situations, computers might not be able to respond appropriately; some decisions require human emotions. Another problem might be that if everything were controlled by computers or robots, people wouldn't have any jobs. 
 Answer: Technology of Future Travel

Article: In films, dads change from cruel men to loving souls. Here is a list of good and bad movies dads .Atticus Finch in To kill a Mockingbird  GOOD DAD:A man whose wife has died with a young family and a busy job as a lawyer, Gregory Peck's character in the  1962 film is one of the great heroes of American cinema  Firm but fair he teaches his children respect and human decency .Harper Lee's novel gets a respectable transposition to film, thanks to Gregory Peck's perfect performance.

Article: A huge cloud of dust rose and an overpass disappeared. This was the scene in Zhuzhou,Hunan Province on May 17.Nine people were killed and 16 injured. Things were similar last year in the Sichuan earthquake. Thousands of people were buried in the ruins and lost their lives. What if we could have warned them? People are always _ to find a way of preventing buildings' collapse. Better materials and technology help,but they are not a solution. Just like humans,a building has its own life cycle from "birth" to "death".If we know when a building is going to collapse,we can repair it in advance or get out of it before it falls. Now,scientists at the University of Illinois have developed a material that turns red before it breaks. The invention could be used in things like climbing ropes or bridge supports. The research was led by Nancy Sottos,a professor at the university's Beckman Institute,and Douglas Davis,a graduate research assistant. The secret behind the colorchanging material is a type of molecule  .A molecule is a group of atoms held together by chemical bonds. Imagine you and your friends standing in a circle,holding hands. Each person stands for one atom,your hands represent the bonds,and the entire circle represents a molecule. If one person lets go of his or her hands,the molecule changes color. The research team put the molecule into a soft material. When the researchers stretched the material,it turned bright red for a few seconds before it broke into two pieces. When they repeatedly stretched and relaxed the material,without breaking it,it only turned a little red. The major problem is that light can get rid of the red color. When the team shone bright light on the molecule,the broken bond was fixed,and the color disappeared. If the bright light keeps the red color from appearing,the material's warning system will be useless. Scientists still have a lot of work to do before the colorchanging molecules can be used outside the lab. 
 Answer: A way of preventing building from collapsing.
