Read the following article and answer the question. Article: Researchers have established that when people are mentally engaged, biochemical changes occur in the brain that allow it to act more effectively in cognitive areas such as attention and memory. This is true regardless of age. People will be alert and receptive if they are faced with information that gets them to think about things they are interested in. And someone with a history of doing more rather than less will go into old age more cognitively sound than someone who has not had an active mind. Many experts are so convinced of the benefits of challenging in the brain that they are putting the theory to work in their own lives. "The idea is not necessarily to learn to memorize large amounts of information," says James Fozard, associate director of the National Institute of Ageing. "Most of us don't need that kind of skill. Such specific training is of less interest than being able to maintain mental alertness." Fozard and others say they challenge their brains with different mental skills, both because they enjoy them and because they are sure that their range of activities will help the way their brains work. Gene Cohen, acting director of the same institute, suggests that people in their old age should engage in mental and physical activities individually as well as in groups. Cohen says that we are frequently advised to keep physically active as we age, but older people need to keep mentally active as well. Those who do are more likely to maintain their intellectual abilities and to be generally happier and better adjusted. "The point is, you need to do both," Cohen says. Intellectual activity actually influences brain-cell health and size. Question: What is the passage mainly about? Answer:
OPTIONS:
- Special mental training for old people.
- Biochemical changes in the human brain.
- The influence of intellectual activities on brain-cell size.
- The importance of mental activities in the efficiency of the brain.

Answer: The importance of mental activities in the efficiency of the brain.

Article: If women are exploited year after year,they have only themselves to blame.Because they tremble at the thought of being seen in public in clothes that are out of fashion ,they are always made use of by the designers and the big stores.Clothes which have been worn only a few times have to be put aside because of the change of fashion.When you come to think of it,only a woman is able to stand in front of a wardrobe packed full of clothes and announcing sadly that she has nothing to wear.

Read the following article and answer the question. Article: There was a strange father, John Blake, from Michigan, who named his children after a computer software term. He told the local newspaper the US traditional way of adding "Junior" or "II" after a boy's name was too common. So, when his son was born last week, he decided on the name John Blake 2.0, as if he were a software programmer. Mr. Blake admitted that it took months to persuade his wife, Jamie, to accept the idea. Mrs. Blake said she asked several friends whether they could accept this name or not. "All the men," she said, "felt the name was cool." However,her women friends did not think so. "I think the women end up like it,"she said. Mr. Blake told the local newspaper he got the idea from a film called The Legend of 1900,in which an abandoned baby is given the name 1900 to remember the year of its birth. "I thought that if they can do it , why can't we?" he said. After little John version 2.0 was born, Mr. Blake even sent a celebratory e-mail to the family and friends, which was designed to look as if he and his wife had created a new software. "I wrote things like there are a lot of new features from Version 1.0 with additional features from Jamie," he said. And he has already planned for his son's future.
