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.

[EX Q]: Article: Wikipedia is an online encyclopedia .This name is a combination of"wiki" and "encyclopedia". Wiki is the Hawaiian word for quick. Wiki websites are designed to enable users to make addition or edit any page Of the site. Wikipedia has been accused of exhibiting systemic prejudice and mistakes.Critics argue that Wikipedia's open nature and a lack of proper sources for much of the information makes it unreliable, Mention Wikipedia within the walls of academy and you'll find no shortage of opinions.That-s no surprise.Can an online encyclopedia that is edited by anyone be trusted as a credible information source? Should students be encouraged to use this tool? And is it even possible to discourage its users? To find out, we performed a simple experiment.We selected 100 terms from the U.S.history textbooks, We chose a mix of items that students might be asked to research for a test or paper and we entered each item into Google to find out which websites the search engine suggests as the most useful links. The results are shocking. Google listed Wikipedia as the number one:  87 times out of 100. Several conclusions can be drawn from this finding. First,  people searching for information about these historical terms are finding the entries from Wikipedia helpful.Second, 6'banning" the use of Wikipedia appears hopelessly simple-minded.Jimmy Wales, one of Wikipedia's founders, told the New York Times, "They might as well suggest not listening to rock & roll either". To our untrained eyes, the information from Wikipedia appeared just as reliable.The reason why the content is mostly reliable is probably that these terms are rather mainstream.The high-school level content is less likely to be wrong than the subjects studied in graduate schools. So when  primary and secondary students are researching history, Wikipedia is still a proper place to start. 
 Answer: Wikipedia is an online encyclopedia edited freely.
[EX A]: Which of the following can best describe Wikipedia?

[EX Q]: Article: Who knows why kids do anything? When it comes to cyberbullying  , they are often motivated by anger or frustration  . Sometimes they do it for entertainment or because they are bored and have too much time on their hands and too many tech toys available to them. Many do it for laughs or to get a reaction. Some do it by accident, without thinking before they do something. The power-hungry do it to make others suffer. And some think they are righting wrong and standing up for others. Because their motives differ, the solutions and responses to each type of cyberbullying incident has to differ, too. There is no "one size fits all" when cyberbullying is concerned. However, education can help considerably in preventing and dealing with the consequences of cyberbullying. If we can help kids understand how much bullying hurts, and how in many cases words can hurt, fewer may cooperate with the cyberbullies. They will think twice before forwarding a hurtful e-mail, or visiting a cyberbullying "vote for the fat girl" site, or allowing others to take videos or cell phone pictures of personal moments.  And, in addition to not lending their efforts to continue the cyberbullying, we also need to teach our children not to stand silently by while others are being hurt. Martin Luther King, Jr. once said that in the end we will remember not the words of our enemies, but the silence of our friends. Kids will feel more comfortable to break the silence if given an anonymous   method of reporting cyberbullying web-sites. School administration, community groups and even school policing staff can receive these anonymous tips and take action quickly. If our children do not allow the cyberbullies to use them to embarrass or hurt others and realize that silence, when others are being hurt, is not acceptable, cyberbullying will quickly stop. It's a tall task, but a noble goal. And in the end, our children will be safer online and offline. We will have helped create a generation of good cybercitizens, controlling the technology instead of being controlled by it. 
 Answer: Standing up for others.
[EX A]: Which of the following is NOT an action of cyber-bullying?

[EX Q]: Article: Scientists in Israel have discovered a new way to test for water pollution by "listening" to what the plants growing in water have to say. By shining a laser beam   on the tiny pieces of _ floating in the water,the researchers said they hear sound waves that tell them the type and amount of contamination   in the water. "It is a red light,telling us that something is beginning to go wrong with the quality of water," said Zvy Dubinsky,an aquatic biologist at Israel's Bar Ilan University."Algae is the first thing to be affected by a change in water quality.""The secret," he said,"is to measure the rate of photosynthesis   in the algae,meaning the plant's ability to transform light into energy." During photosynthesis,plants also release oxygen into the air. Dubinsky's technique is easy to perform because of the overabundance of algae in the planet's water.Most of the oxygen in the atmosphere comes from algae.A prototype tester that occupies about one square meter of a laboratory desktop,shoots a laser beam at water samples to stimulate photosynthesis in the algae.But not all of the laser's heat is used.Depending on the condition of the algae and the rate of photosynthesis,some of the heat is shot back into the water,creating sound waves,Dubinsky said.With a special underwater microphone,researchers are able to analyze the strength of the sound waves and determine the health of the algae and the condition of the surrounding water. "Algae suffering from lead poisoning,like waste discharged from battery and paint manufacturing plants,will produce a different sound than those suffering from lack of iron or exposure to other toxins," said researcher Yulia Pinchasov.She said that testing algae photosynthesis can determine water quality more accurately and easily than laborintensive methods now used like chemical and radioactive carbon testing. 
 Answer: Because it can produce different sounds.
[EX A]:
Why is the algae tested?
