Question: Write a multi-choice question for the following article: Article: A trip across the Pacific will guarantee you a different experience with a tipping culture you've never come across in China. In the US, giving a little extra money to service workers on top of your bill is a common practice. Though US national law requires that businesses pay workers at least $7.25 (45 yuan) per hour, employees receiving tips--often waiters and waitresses--are the exceptions. They usually only receive at least $2.13 an hour, and tips make up the difference. As theWall Street Journalput it, "The American system of tipping holds the promise of great rewards for waiting staff." So how should you tip if you are in the US. Normally you pay tips as a percentage of the bill. Offering an extra 15 percent of the bill to the waiter or waitress in a restaurant and to the delivery man or woman is customary and expected. You can offer more for great service and less for poor service. Yet there is an exception. For take-out food, you don't have to provide tips, though some people say that filling an order still requires work and time that deserve a little extra--but maybe a little less. Tips are not expected at fast food restaurants, cafes or ice cream shops either, though a tip jar might be right by the cash register . Don't feel _ to throw some money in, but also remember that it doesn't hurt. Those workers do not rely on tips. Other service workers also receive tips. For taxi drivers, 15 percent is the norm , more if they help with your bags. Hairdressers often receive about 15 percent of the bill. The same goes for spa therapists and tour guides. Today, you can even pay tips on a credit card. When receiving a copy of the bill to sign, you are free to fill in how much you'd like to tip. Though thinking about when to tip and how much you should tip causes a big headache for many Chinese people, it's important to bear in mind that as long as you show respect and use your reasoning, things will be just fine.
Answer: Question: According to the author, Chinese consumers _ .Options:A don't necessarily have to follow the tipping rules in the USB should use their credit cards to give tipsC must argue about the amount of tip they have to payD should take it easy and give the correct tips for different occasionsAnswer:D

[Q]: Write a multi-choice question for the following article: Article: Scientists are learning new things about Antarctica, the coldest place on Earth. For example, the Antarctic ice sheet is shrinking. A new study found that summer ice loss in parts of Antarctica was at its highest level in 1,000 years. The study showed that Antarctic ice was melting mostly from below ice shelves, where the water is warmer than the ice. Eric Rignot is an earth system expert at the University of California, Irvine. He also works for the American space agency, NASA. There he serves as senior research scientist at NASA's Jet Propulsion Laboratory, also in California. He says ice melting from below is responsible for 55 percent of the shelf loss from 2003 to 2008. That is a much higher rate than scientists thought earlier. Professor Rignot and his team used satellite observations, radar and computer models to measure features above the ice to learn what was going on below. The measurements show differences from one area to the next around the continent. The major ice shelves are called Ross, Filchner and Ronne. They make up two-thirds of Antarctica's ice shelves. But they are responsible for only 15 percent of the melting ice. The professor says even small changes, like changes in ocean flow driven by wind, can make a huge difference in the melting of the ice shelf. Sixty percent of the Earth's fresh water is held in the huge Antarctic ice sheet. Professor Rignot says the study will help experts predict how the continent reacts to warmer ocean waters and helps to cause rising sea levels around the world. The study was published in the journal Science.

input: Please answer the following: Write a multi-choice question for the following article: Article: Rats that eat high levels of a natural sugar known as fructose seem to age faster than other rats.and the same could be true for people who eat too much sweet junk food,Israeli researchers said Monday. Fructose,found naturally in honey and fruit,is used widely in foods ranging from soft drinks to yogurt.But while its sweet taste is popular,the sugar could cause wrinkles,the researchers said.Dr.Moshe Werman and Boaz Levi of the Technion-Israel Institute of Technology fed large amounts of fructose to laboratory rats.Writing in the Journal of Nutrition,they said the fructose-fed rats showed changes in the collagen of their skin and bones.Collagen basically holds the body together.The loss of collagen is what causes loose skin and deep wrinkles in older people. The process affected,Werman's team said,is known as"cross-linking "."Too much cross.1inking makes the skin stiff, and these are the conditions that encourage wrink1ed skin,"Werman said in a statement.He said the same could be true of people,although this has not been shown."Americans are eating more and more processed foods such as baked goods,canned fruits,jams is and dairy products that contain fructose,"Werman said.Other studies have shown that taking in high fructose may cause diabetes . The rats Werman worked with were fed much more than the average adult person might eat in a day,which is standard in such experiments.The rats were fed 12.5 grams of fructose per kg of weight everyday for a year.
