We invited staff volunteers who had a strong liking for either CocaCola Classic or Pepsi, Diet Coke, or Diet Pepsi. These were people who thought they'd have no trouble telling their brand from the other brand.
We eventually located 19 regular cola drinkers and 27 diet cola drinkers. Then we fed them four unidentified samples of cola one at a time, regular colas for the one group, diet versions for the other. We asked them to tell us whether each sample was Coke or Pepsi; then we analyzed the records statistically to compare the participants' choices with what mere guesswork could have accomplished.
Getting all four samples right was a tough test, but not too though, for people who believed they could recognize their brand. In the end, only 7 out of 19 regular cola drinkers correctly identified their brand of choice in all four trials. The diet cola drinkers did a little worse -- only 7 out of 27 identified all four samples correctly.
While both groups did better than chance would predict; nearly half the participants in each group made the wrong choice two or more times. Two people got all four samples wrong. Overall, half the participants did about as well on the last round of tasting as on the first, so fatigue, or taste burnout, was not a factor. Our preference test results suggest that only a few Pepsi participants and Coke fans may really be able to tell their favorite brand by taste and price.
According to the passage the preference test was conducted in order to ______.

听力原文： Farming in Britain has changed a great deal in the last 30 years. Farming used to employ a great many people in Britain but nowadays, with machinery, a few people can run a huge farm of thousands of hectares.
Agriculture provides around 60 percent of Britain's food needs even though it employs just 2 percent of the country's labor force. Britain's agriculture is under pressure to change at the moment. Farmers are under pressure to adopt more environmentally friendly methods such as organic farming. Organic farming does not use artificial chemicals that can damage the environment and human health. Its popularity has grown rapidly in recent years. Different types of farming occur in different regions of Britain. This is due to the influence of relief, climate, and soil type and to an extent closeness to the market. Upland areas generally lend themselves to sheep farming. Flat areas to crop production and wet/warm areas to milk and beef production.
Some parts of Britain have excellent soil for crops, while others are used for cattle, sheep, pigs and poultry.
In the northwest of England, Wales and Scotland, farmers keep cattle and sheep. Sheep can survive the cold winters on the hills and moors.
In the southwest of England, the rich grass is ideal for feeding dairy cows.
In the southeast of England and the lowlands of Scotland, grain, potatoes and sugar beet are grown.
In East Anglia (Norfolk, Suffolk and Essex), wheat, barley and vegetables grow in enormous fields.

听力原文： Colds have always been a nuisance, and people have tried many strange ways to cure them, However, none have worked. one Roman historian even recommended kissing the nose of a hairy mouse (29) ! But up till now we are only a little closer to finding a cure for it.
Scientists have discovered that a cold is not caused by a single virus, but by many. They have proved that people under stress are more likely to catch colds, although why this happens is still unknown (30) . Experiments also showed that women suffer more colds than men. But again, scientists are unable to explain why this is so.
Another experiment proved that getting cold does not cause colds. For this experiment, one group of human volunteers were showered with water and then made to stand in a windy corridor. Another group remained dry and inside a heated room. While you might expect people in the first group to catch colds more easily, they didn't.
one other thing that we now know is that colds are spread by water vapor from breath. This would explain why colds are more common in the winter than at other times: people spend more time indoors closer to other people, and also away from flesh air (31) .
