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.

[Q]: 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.

[Q]: Article: In choosing a friend,one should be very careful.A good friend can help you study.You can have fun together and make each other happy.Sometimes you will meet fair weather friends.They will be with you as long as you have money or luck,but when you are down,they will run away.How do I know when I have found a good friend?I look for certain qualities of character,especially understanding,honesty and reliability .

[Q]: Article: The earliest newspapers started in ancient Rome. They were handwritten news sheets. The first printed newspapers appeared in China during the Tang dynasty, which were printed from carved wooden blocks. Modern papers first appeared in Venice, Italy in the middle of the 14th century. The newspapers of today, with advertising and a mixture of political, economic, and social news and comments, were started in Britain in the mid-18th century. The main function of newspapers is to report news. Many newspapers also provide special information to readers, such as weather reports and television timetables. They also provide comments on politics, economics, arts and culture. Almost all newspapers depend on advertising to make money. Nearly six out of ten adults in the United States and Canada read a newspaper every day. Seven out of ten read a paper each weekend. Readers search newspapers for de-tailed background information and analysis . This is what television and radio news reports seldom offer. Newspapers tell readers what happened, and they also help readers understand what caused an event and how it will affect the world around them. The workers at large newspaper companies work under a lot of pressure to bring news to readers as soon as possible. Reporters, photographers, artists, and editors collect articles in just a few hours. Page designers select articles, photos, advertisements, and eye-catching headlines to make the pages, and then rush their work to the printer. Printing workers may work overnight around printing presses to _ more than 60,000 copies per hour.
