Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Last year college students in America spent an estimated $700 on textbooks on average. The National Association of College Stores reported more than five billion dollars in sales of textbooks and course materials. The association spokesman Charles Schmidt says electronic textbooks now just make up 2%~3% of sales. But he says that is expected to reach 10%~15% by 2012. Online versions are now available for many of the most popular college textbooks. An etextbook can cost half the price of a new print textbook. But students usually lose access to them after the end of the term. And the books cannot be placed on more than one device ,so they are not easy to share. So what do students think of etextbooks?Administrators at Northwest Missouri State University wanted to find it out. Earlier this year they tested them with 500 students in 20 classes. The university is unusual. It provides laptop computers for all 7,000 of its fulltime students. It does not require students to buy their textbooks either. They rent them to save money. The school aims to save even more by moving to etextbooks. The students in the survey reported that downloading the books from the Internet was easy. They liked the idea of carrying lighter backpacks. And 56% said they were better able to find information. But most found that using etextbooks did not change their study habits. And 60% felt they read more when they were reading on paper. In all,almost half the students said they still liked physical textbooks better. But the survey found that cost could be a big influence.55% said they would choose etextbooks if using them meant their textbook rental fee would not increase. Roger Von Holzen heads the Center for Information Technology in Education at Northwest Missouri State University. He tells us that administrators are disappointed with the etextbooks now available because the majority are not interactive . He thinks growth will come when more digital books include video,activities,games and other ways to interact with the information.... Options: A they cost more money B they're difficult to carry C they're not convenient to share D they can't be downloaded from the Internet Answer: C they're not convenient to share Question:
Answer: Etextbooks are not better than paper books in that _ .

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Tiny monitoring devices have become an increasingly common way for scientists to study elusive animals that are difficult to track on a day-to-day basis. However, now it seems that smart. seals have caught on to the trick and are using it to their advantage to catch fish! To find out if that is true, a team of researchers from the University of St. Andrews in Scotland selected a group often young grey seals that had neither encountered the ocean nor been exposed to any kind of acoustic tags. The researchers then placed the seals one at a time, inside a pool that contained 20 foraging boxes, only two of which housed fish -- one with tags and the other without. Each seal was allowed to explore the boxes twenty separate times. In order to ensure that mammal was not depending on its memory, the fish were moved to different boxes each time. At first, there was no difference in the amount of time it took the seals to discover the tagged and untagged fish. However, after they had been in the pool a few times, they started locating the tagged fish much faster. To confirm that this indeed was the case, there searchers conducted a second experiment using two boxes -- one with pieces of fish and the other with just acoustic tags. Sure enough, the seals were all attracted to the one that was sending out signals. While this experiment involved only seals, the researchers believe that other marine mammals may also be using the information to catch prey. Sadly, predators like sharks that have been tagged by scientists may be negatively affected, as pings they emit could warn their prey of their presence. Besides potentially messing up nature's food chain, the "dinner bell" effect of the acoustic tags could also mean that the conclusions reached by previous fish studies may not be correct. Now that the secret is out, scientists will have to come up with another way to conduct their studies -- one that is not detectable by the crafty marine animals. Options: A They have acoustic tags attached to them. B They have better hearing than normal seals. C They have been trained to recognize acoustic tags. D They were not born in the ocean. Answer: D They were not born in the ocean. Question:

[A]: What is implied about the ten young grey seals?

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Three men were travelling across the desert when their car broke down. There were no other traffics, so their only hope was to walk. Before they set off, they looked around in the car for useful things to take with them. One of the men took a bottle of whisky. Another took an umbrella. The third unscrewed a door from the car and carried that. After they had been walking for almost a day, they came across a camel caravan travelling towards them. "Let's try to join the caravan," one of the men said. "It's going the wrong way but we'll be safer than if we keep on alone across the desert." The other s agreed, so they asked the leader of the caravan for permission to join it. "You can join the caravan only if you answer three questions," he said. He pointed to the first man's bottle. "What is that and why are you carrying it?" he asked. "It's a bottle of whisky. I decided to carry it with me so that if I feel miserable and want to give up, I can get drunk, cheer myself up and then keep on walking." "Very sensible," the leader of the caravan said. Then he pointed to the next man and his umbrella. "It hasn't rained in the desert for many years," he said. "Why are you carrying an umbrella?" "I don't want to get heat exhaustion," he replied. "The umbrella will give me shade from the sun." "Very sensible," the leader of the caravan said. He pointed to the third man and his car door. "And why are you carrying a car door?" he asked him. "I thought that if I got too hot I could open the window and let some air in," he explained. Options: A if they could join the caravan B how to get out of the desert C how to avoid heat exhaustion D where he kept his umbrella Answer: A if they could join the caravan Question:
