input question: Write a multi-choice question for the following article, with the given choices and answer: Article: In fall 2006,the National Basketball Association (NBA)started using basketballs made with synthetic ,or man-made ,material instead of leather .They made the change be- cause they wanted every basketball they use to feel and bounce the same.Not all leather balls are exactly alike in weight or how they bounce,but the synthetic balls are. However,some players complained right away that the new balls bounced differently and were actually harder to control than the leather ones. Physics helped answer questions about why the new balls felt different.For example,the scientists studied friction ,which in this case affects the ability of a player to hold onto a ball."The greater the friction,the better it will stick to his hand,"explains a scientist. Tests on both wet and dry balls showed that while the synthetic ball was easier to hold onto when dry,it had less friction and became much harder to hold onto when wet.That's because _ stays on the surface of the synthetic balls but gets taken into the leather balls. The scientists also tested bounce and found that the logo printed on the new balls made their surface uneven and caused them to bounce a little strangely com- pared with the leather balls. In January,the NBA went back to using the leather balls.They aren't perfect,but for now,that's just the way the ball bounces. Options: A it is wet B it is dry C there's a logo on it D its weight remains the same Answer: C there's a logo on it Question:???

Lang Lang, 26, is the first Chinese pianist to play with the world's top orchestras ,making his first appearance at the Carnegie Hall in New York at 18, while still a student. Lang's charm and fondness make him a natural fit to represent China's new international image. According to the British newspaper the Times, "The Lang Lang effect" drives 36 million Chinese children to learn the piano. Now in China, children are learning Chopin and Western orchestras are playing sold-out tours across Chinese cities. But can China ever introduce its own music to the West? Lang is trying. His cooperation with the London Symphony Orchestra this month includes a performance of Dragon Songs, an album of traditional Chinese classics. Behind the success , however, is a surprising story of a gifted child. Lang grew up with his father's own musical ambition and high expectations. It is not hard to imagine how boring it must be to practice the piano every day. Lang said that he once hated his hands and the piano. He got his right hand hurt six years ago and had to rest. "That was the best month," he says. Options: A He played in the Beijing Olympic opening ceremony in 2008. B He usually plays with the world's top orchestras.

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: When you are learning English, you find it not clever to put an English sentence, word for word, into your own language. Take the sentence "How do you do?" as an example. If you look up each word in the dictionary, one at a time, what is your translation ? It must be a wrong sentence in your own language. Languages do not just have different sounds, they are different in many ways. It's important to master the rules for word order in the study of English, too. If the speaker puts words in a wrong order, the listener can't understand the speaker's sentence easily.Sometimes when the order of words in an English sentence is changed, the meaning of the sentence changes. But sometimes the order is changed, the meaning of the sentence doesn't change. Let's see the difference between the two sentences:"She only likes apples. " "Only she likes apples. " When you are learning English, you must use it as the English speaker does. Options: A difficult to understand different sounds B possible to remember the word order C important to master the rules in different ways D easy to master the rules for word order Answer: C important to master the rules in different ways Question:
