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: 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.
What causes tremors and quakes according to the passage?

Article: Coca-Cola is probably the most famous brand in the world, and in some areasyou can even access it easier than clean drinkable water. Although the company is trying to present itself as a health-conscious company, you can't really say that drinking cola is healthy for you. Still, we all drink cola, some more and some less, and we tell ourselves that it's all okay as long as we don't overdo it. However, Coca-Cola has other functions besides drinking. Cola removes the tarnish from old pennies. Got some old rusty pennies? Not to worry! Put them inside a glass of cola and let them rest for a while. When you get them out, you'll have shiny pennies that will look as if they were coined a couple of days ago. If you couldn't clean those pennies with industrial acids, just buy a can of cola and let it do its magic! You can remove gum from your hair with cola. If you've got gum stuck in your hair and don't know a better way to get it out, don't worry, you won't have to cut it. Just pour some cola into a bowl and dip the part of your hair with gum on it inside. Leave it for a couple of minutes and then simply wipe off the gum. You can make an exploding fountain. You probably know about this one. You can make an exploding fountain by putting a mint inside a two-liter bottle. Then move away from the bottle and get ready for a Coca-Cola explosion. This is a fun thing to do, but it is also a warning -- don't eat a mint and drink cola at the same time, because a similar thing could happen to your stomach.
Answer: Take the place of acids.
What can cola be used to do?

Article: Salesman Ramesh lived in the southern part of India. He got his first assignment in the month of June, the start of the rainy season in the area. He was given a list of local laundry owners whom he had to approach and sell products to. He was scared and thought he wouldn't be able to fulfill the task, but he accepted the challenge as he had no other choice. The next day he started approaching the laundry owners, and within 15 days he got a really nice response. Most of them purchased his products, but they borrowed money from Ramesh to buy the products. Everyone promised to pay him back within the next 15 days. During the last week of June amidst heavy showers, he started visiting the laundry owners to collect money. Upon visiting half of them, he realized he hadn't collected a penny. After almost 14 days, on a bright sunny Monday morning, he started visiting the laundry owners once again. Suddenly, by noon Ramesh realized that he had collected the payments from almost 50% of the owners. He worked hard throughout the day, and by the end of the day he had completed 90% of his target for June and July. At last, he became the "star performer" for the months of June and July. Why did the laundry owners look at the sky and tell him to come the next day when Ramesh visited them? He went to a laundry owner and asked him the question. The owner said, "This is the month of the rainy season and we have to wash the clothes, dry them off and iron them before handing them over to customers. If the sun doesn't shine, how can we dry our clothes and earn money to pay you back?" Ramesh then realized that it was his patience and endurance that kept him going and ultimately helped him achieve success. Like Ramesh, each one of us should realize that apart from being honest and hard-working, if we can keep our patience, we are inching up the ladder of success.
Answer: He accomplished his sales task perfectly within 10 days.
