Read the following article and answer the question. Article: Losing weight comes with a lot of health benefits--including making your brain sharper. Yes, it turns out that overweight may damage cognitive functions such as memory and attention. There have been few studies of overweight and cognitive functioning, possibly because it is generally believed that it is not a primary risk cause for poor cognitive performance. Losing weight, therefore, may help improve these mental functions, according to a new research led by John Gunstad, assistant professor of psychology at Kent State University. Growing evidence suggests that being fat is linked to cognitive deficits . So Gunstad and his team guessed that losing weight might improve mental function. For their study, they measured memory and attention in a group of 150 overweight participants, some of whom had some kind of operation for weight loss and some did not. All of the volunteers completed mental skills tests to assess their abilities of memory and attention at the beginning of the study, and again 12 weeks later. To begin with, about 24% of the patients showed damaged learning and 23% showed signs of poor memory when tested. At the end of the study, those who had lost weight after operation improved their scores into the average or above average range for cognitive functions. Scores for the volunteers who didn't lose weight dropped even further. The study helped Gunstad to find out whether losing weight had any effect on mental function. Now that he's seen the positive effect that weight loss can have on memory and attention, he says he will next study those who choose to lose weight by the traditional way--eating healthier and getting more active. He expects that losing weight in this way will have a similarly positive effect on the brain. "If we can improve the condition with operations, then we can probably produce the same change with behavioral weight loss as well," he says. Question: There is less research on overweight and cognitive functions because researchers _ . Answer:

OPTIONS:
- believe overweight only affects our body
- have focused on ways to sharpen people's mind
- do not consider overweight a main cause for low cognitive ability
- are clear about the relation between weight and mental functions

Answer: do not consider overweight a main cause for low cognitive ability

Read the following article and answer the question. Article: Frank Woolworth was born in Rodman, New York, in 1852. His family were very poor farmers, and there was never enough to eat. Frank decided he did not want to be a farmer. He took a short business course, and went to work as a salesman in a large city. Woolworth realized he had a natural skill for showing goods to attract people's interest, but he soon learned something more important. One day his boss told him to sell some odds and ends ( ) for as much as he could get. Frank put all these things on one table with a sign which said FIVE CENTS EACH. People fought and pushed to buy the things and the table was soon cleared. Soon afterwards, Woolworth opened his own store, selling goods at five and ten cents. But he had another lesson to learn before he became successful. That is, if you want to make money by selling low-price goods, you have to buy them in large quantities directly from the factories. Once, for example, Woolworth went to Germany and placed an order for knives. The order was so large that the factory had to keep running 24 hours a day for a whole year. In this way, the price of the knives was cut down by half. By 1919, Woolworth had over 1000 stores in the US and Canada, and opened his first store in London. He made many millions and his name became famous throughout the world. He always runs his business according to strict rules, of which the most important was: "THE CUSTOMER IS ALWAYS RIGHT."www.ks5u.com Question: Frank sold the odds and ends quickly because _ . Answer:
