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.

Example Input: Article: A new study revealed that the formation of the Earth, Sun and Moon that cause changes in Earth's tides can also trigger a special kind of Earthquake along the California's San Andreas Fault . The study, published in the journal Proceedings of the National Academy of Science,is based on previous researcher suggesting that the gravitational tug of sun and moon is not only affecting the sea levels of Earth, but can also stretch and compress that Earth's crust, producing tremors and quakes. Furthermore, the new study showed that small tremors deep underground were more likely to occur during certain periods of the tidal cycle. For the study, the researchers looked at about 81,000 low-frequency earthquakes from 2008 to 2015 along the Parkfield section of the San Andreas Fault and compared it to the two-week tidal cycle known as the "fortnightly tide," Low-frequency earthquakes are named due to the rumbling sound they make and not by the rate of its occurrence. These kinds of earthquake only occur about 15 to 30 kilometers below ground and are no larger than magnitude 1 in the Richter scale. The researchers discovered that low-frequency earthquakes tend to occur during the waxing period of the tidal cycle, when the tides are getting little by little. It is already known that the strongest Earth tides occur when the sun and moon are in a straight line, while the tide is at its weakest state when the sun and moon are 90 degrees apart. According to the researchers, low-frequency earthquakes show that some part of the San Andreas Fault is creeping, or slowly moving, almost all the time. With the help of the tidal forces, low-frequency earthquakes could provide more information about the deeper part of the fault. "They tell us that the fault continues down below where the regular or typical earthquakes stop on the San Andreas, about 10 or 12 km (about 6 to 7 miles)," said David Shelly, a seismologist at USGS and helped write the study, in a statement. "And they tell us a lot of things about that deep part of the fault that we had no idea existed at all before." "It's almost like having a lot of little creep meters embedded in the fault,"Shelly said. "We can use these low-frequency earthquakes as measurements of, at least in a sense, how much slip is happening at each little spot on the deep part of the fault where we see these events. When we don't see them, we don't know what's happening; we don't know whether it,s slipping silently or not slipping at all." The information is incredibly useful, he added. Whenever the deep part of the fault slips, the stress gets transferred to the shallow part of the fault. "So if all of a sudden, we saw that the deep part of the fault was slipping a huge amount, it might be an indication that there was an increased chance of having an earthquake come at the shallower part of the fault" he said.
Answer: The movement of creeping in the deep part of the San Andres Fault.
Example Output: What causes tremors and quakes according to the passage?

Example Input: Article: Instead of a normal court hearing, the trial on Wednesday appeared more like a prepared drama. Hundreds of reporters waited outside the court, in the hope of learning "shocking" information about the case, which includes well-known military singer Li Shuangjiang's son, who gang-raped a woman with another four men on February. The case was not a public hearing because it includes teenagers, whose privacy must be protected under law, but many details had been exposed by the lawyers before the trial. Lawyers of all five suspects and the woman's lawyer made a lot of debate on the Internet before the trial, making the case more confused. Wu Ming'an, a law professor from the China University of Political Science and Law, said it was a pity to see such a "performance" by the lawyers. "It can be understood that the two parties freely spoke their opinions, but it's not professional or wise to see lawyers do the same," Wu said. "Instead, the lawyers should guide and persuade their clients to calm down, especially for such a non-public and sensitive case." China has no clear rule to manage lawyers' behavior before trials, "but it should be general knowledge that the lawyers of the two sides cannot _ too many details, particularly in a case that includes teenagers", Wu added. Yi Shenghua, a lawyer who has been following the case, said it does more harm than good to both parties for such detailed information to be exposed before the trial. "It's OK for lawyers to speak, but what is said must be reasonable and legal. Although judgments should not be affected by public opinion, it's hard for them not to be," he said, suggesting judicial authorities should speak out if the case goes wrongly. Trials must be conducted based on evidence, while lawyers should protect their clients' rights instead of adding fuel to the flames, Yi said. In my eyes, the most important aspect of the case, lies in how to make lawyers do their work more professionally and reasonably.
Answer: Because many details had already been exposed before the trial.
Example Output: Why was the case not a public hearing?

Example Input: Article: Brad Pitt and Angelina Jolie have given $500,000 to help the town of Joplin --a town near the Mississippi River, where Pitt's mother went to school recover from a huge tornado that struck on May 22, 2011. The couple made the donation through the Jolie-Pitt Foundation on Thursday to help rebuild the town of Joplin after about 30% of the buildings were destroyed by the tornado. Over 150 people were killed. "The Joplin community faces great challenges ahead," said Brad. "Having spent most of my childhood there, I know these people to be hardworking, humble and especially resilient. "The locally based Community Foundation of the Ozarks will be working shoulder to shoulder with these Joplin citizens for long to rebuild their lives. We, too, hope to further help with these rebuilding efforts." "Last year 42 million people worldwide were hurt by natural disasters," added Angelina. "So often, these disasters seem far away; but now, the need is right here at home for thousands of people. Our hearts go out to the families in Joplin who have lost so much." The Community Foundation of the Ozarks was founded in 1973 and has since grown to include 43 branch community foundations. The Foundation's task is to improve the quality of life in the Missouri Ozarks area through resource development, community grant making, working together, and public leadership. "We had a call in the first day or two afterward from an organization representing them," said Brian Fogle, president of the Community Foundation of the Ozarks. "They made several calls afterwards, but we learned that they made a donation.
Answer: in the USA
Example Output:
Where did the disaster most probably happen?
