input: OPTIONS:
- intellectual stimulation from others makes the brain work better
- people should avoid working with those intellectually challenged
- one's IQ could be held back if he has bright brothers or sisters
- the IQ of children is least influenced by the understanding level of a family Now, answer this question: Read the following article and answer the question. Article: Next time you raise an eyebrow at the views of your partner, friend, sibling or colleague, remember they could be helping to make you smarter. New research shows that intelligence is not fixed but can be boosted throughout adulthood by family members, bright mates and intellectually stretching careers. The study challenges the commonly held belief that intelligence is static by the age of about 18. Current scientific consensus suggests that intelligence is controlled by genes, with environmental factors such as schooling and nutrition playing a partial role up to this age. After this point, IQ scores stabilize . But James Flynn, professor of political studies and psychology at the University of Otago in New Zealand, argues that people can "upgrade" their own intelligence throughout their lives. He believes intellectual stimulation from others is crucial as the "brain seems to be rather like a muscle - the more you use it, the stronger it gets". However, the opposite is also true - so people sharing a home or workplace with those who are intellectually challenged risk seeing their IQ levels fall as a result. He found the "understanding quality" of a family changes the IQs of all members, especially children. It can "lift" or hold back, depending on the "gap between their brightness and that of their siblings and parents". A bright ten-year-old with brothers and sisters of average intelligence will suffer a five to ten point IQ disadvantage, compared to a similar child with equally bright siblings. However, children with a low IQ could gain six to eight points by having brighter siblings and special educational treatment to help pull them up. Professor Flynn also concluded that although genetics and early life experiences determine about 80 percent of intelligence, the remaining 20 percent is linked to lifestyle. This means that people can raise their IQ, or allow it to fall, by ten points or more. Therefore, the best way to boost IQ level is to mix with bright friends, find an intellectually challenging...

input: OPTIONS:
- Visiting customers themselves.
- Giving customers free food on the street.
- Visiting parks as ordinary customers.
- Asking customers questions at supermarkets. Now, answer this question: Read the following article and answer the question. Article: As societies develop, their members start to see things not so much according to what they need, but according to what they want. When people have enough money, these wants become demands. Now, it' s important for the managers in a company to understand what their customers want if they are going to develop effective marketing strategies . There are various ways of doing this. One way at supermarkets, for example, is to interview customers while they're doing their shopping. They can be asked what they prefer to buy and then the results of the research can be studied. This provides information on which to base future marketing strategies. It' s also quite normal for top managers from department stores to spend a day or two each month visiting stores and mixing freely with the public, as if they were ordinary customers, to get an idea of how customers act. Another way to get information from customers is to give them something. For example, some fast food restaurants give away tickets in magazines or on the street that permit customers to get part of their meal for nothing. As well as being a good way of attracting customers into the restaurants to spend their money, it also allows the managers to get a feel for where to attract customers and which age-groups to attract. Another strategy used at some well-known parks such as Disneyland is for top managers to spend at least one day in their work, touring the park dressed as Mickey Mouse or something like that. This provides them with a perfect chance to examine the scene and watch the customers without being noticed. Question: Which of the following can help managers get useful information? Answer:
A:
output:
Asking customers questions at supermarkets.
