It covers 788 square miles and has a population of 1,00,000, about 750.000 Indians, 300,000 Chinese and 20,000 Whites included. They are living together peacefully, although they share such different beliefs as Hindu, Roman Catholic, Muslim and so on. The country can be divided into many parts with different climate all because of its peculiar terrains . In the center there are volcanoes several thousand feet high, and 90% of its arable land is covered with sugarcane. There are no people living on the island before the Dutch landed on it in 1638. The Dutch _ it in 1710, and five years later, the French came and succeeded in planting sugarcane there. It was conquered byBritainin 1818. As a result, its official language is English. The main big cities are Beau - Bassin and Mahebourg, withPort Louisas its capital. Mauritius has many rare and unique animals, such as the snakes, parrots and lizards. The giraffe is a type of animal with a very long neck and legs and yellow skin with dark spots. It is the tallest of all living animals. Mauritius was extremely poor when it declared its independence in 1968. In the past ten years, obvious economic prosperity has shown itself in this island country. Nowadays its business, culture and tourism are developing rapidly. Every year, thousands of millions of people rush there to enjoy the silver sand beach and song and dance performances with native national characters.

Problem: Write a multi-choice question for the following article: Article: ALMOST everyone wants to get smarter. We struggle to improve our memory, intelligence, and attention span. We drink cup after cup of coffee to help us get through the day. However, a new study published in the journal Current Directions in Psychological Science warns that there are limits to how smart humans can get, and trying to increase your thinking ability could beurisky. Each of our body parts evolved in a certain way for a reason. For example, we are not 3 meters tall because most people's hearts are not strong enough to send blood up that high. Scientists are now saying that our thinking ability works in the same way. A baby's brain size is limited by a series of factors, such as the size of the mother's pelvis . If our brains evolved to vbe bigger, there could be more deaths during childbirth. The study of Ashkenazi Jews , who have an average IQ much higher than other Europeans, showed that they were more likely to develop diseases of the nervous system. This might be because of their increased brainpower. If intelligence cannot be improved, can we at least get better at concentrating? Not really, say scientists. They studied drugs like caffeine that improve attention span. They found that the drugs only helped people with serious attention problems. For those who did not have trouble paying attention, the drugs could have the opposite effect. Scientists say that this suggests there is an upper limit to how much people can or should concentrate. Our memory is also a "double-edged sword ". People with extremely vivid memories could end up having a difficult life because they cannot forget bad things that happen to them. Thomas Hills of the University of Warwick in the UK, one of the authors of the paper, said that considering all the problems in trying to get smarter, it's unlikely there will ever be a "supermind".

A: Question: What does the author mean by saying "Our memory is also a 'double-edged sword '"?Options:A Good memory can lead to bad results, too.B Good memory will lead to diseases in people's body.C Without memory, people will lead a better life.D Poor memory makes people more generous.Answer:A

Q: Write a multi-choice question for the following article: Article: A team led by Professor Theoder Berger, from the University of Southern California, can now manipulate brain cells in rats so that memories stored in the hippocampus, a brain area crucial for memory formation, are activated or suppressed . It's said that _ could one day have medical applications. In the study, researcher first trained rats to remember which of two levers they pressed first, then to press the other lever. As the rats performed the task, the scientists carefully monitored the electrical activity in each creature's hippocampus to find the pattern of nerve-cell activity involved in making a solid memory. Using the same glass needles they had used to record the nerve activity, they stimulated nerves in the same pattern and found that the animals' performance in the task got even better. The rats made fewer errors and were able to remember which lever was the"correct"one for a longer period of time. The scientists went a step further and suppressed the rats' memories with a drug called Mk801, which caused them to forget their task. When the animals' brain cells were later stimulated with the"correct"pattern, they remembered again which lever to press. "What's really exciting about this study is that when they played back the'good' patterns--the patterns when the animal got the task right--it did appear to improve memory,"said Dean Buonomano, an associate professor at the University of California. The final goal, Berger said, is to help people with stroke and epilepsy and the like strengthen memories and to help doctors treat them. The technology might even help sufferers of post-traumatic stress disorder. But first, researchers would have to show that they can stimulate or suppress far more complex memories than the ones in the rat experiment. "Here ,it's a simple task,"Buonomano said. In contrast, humans' memories are very rich and specific... "We have very many steps to go before this can be achieved,"he said.
A:
Question: What can we infer from the article?Options:A MK801 is a drug that can be used to stimulate nerves.B The study is expected to be used to help stroke and epilepsy patients recover completely.C Using the study to improve humans' memories still face many challenges.D Researchers have studied far more complex memories than the ones in the rat experiment.Answer:C
