[EX Q]: Article: Are you sitting down?In that case,you should probably stand up before reading this. In the first advice of its kind,British experts are recommending office workers stand for at least two hours. day,in a warning against the dangers of prolonged sitting .The,idelines were developed by a group of experts invited by Public Health England and an advocacy up *and were published online Monday in Sports Medicine. Compared to those of smoking,people who sit the most have more than twice the risk of developing Type 2 diabetes and cardiovascular disease,.a 13 percent increased risk of cancer and a 17 percent increased risk of premature death ,compared to those who sit the least. "Even if you're meeting your physical activity guidelines,you cannot get rid of the risks of prolonged sitting,"said Uavin Bradley,director of the campaign group Get Britain Standing,one of the authors of the new guidance .Bradley,who spoke during a telephone interview while walking,said officials figure out the average Briton sits for more than half of their working hours.His group is expanding its campaign to other countries including the U.S.on Tuesday and is pushing for more people to have access to a desk that allows them to stand. "Companies should reconsider the culture around taking regular breaks and think about whether meetings could be held standing up or walking,"said Bradley."We've sat on this problem for far too long*"
Answer: .advocate people to stand more
[EX A]: The passage is mainly written to _ *

[EX Q]: Article: There are some things humans can go without. We can lose a kidney or a lung, an arm or two and still live perfectly well. But some fish put us to shame. They can _ without stomachs. One such fish is the stout longtom. The group it belongs to carries a more appropriate name: the needlefish. All needlefish lack stomachs. Their ancestors had them, but later they were lost. The stout longtom can reach 1.3 meters in length, and lives near the sea surface. Like all needlefish, it can jump out of the water to escape its enemies. Tropical fishermen are sometimes injured by needlefish. In 1977, a 10-year-old Hawaiian boy was killed when a needlefish jumped through his brain. The longtom eats smaller fish. It teeth are not good at cutting fish into pieces, so it swallows fish whole. Ryan Day from Australia and his colleagues wanted to know how the longtom digests its meaty meals without a stomach, so they ran some chemical tests about the fish. Day's results show that the longtom can consume food without the help of a stomach. It uses a special material called trypsin that can break down proteins without acid -- although the approach is less efficient than using a stomach. Because it's a meat-eating animal, the longtom gets a lot of protein in its food, so it can afford this slightly less efficient system for absorbing it. Two plant-eating fish that Day studies actually had higher levels of trypsin in their body, as their food was low in protein. Day thinks that the longtom and its stomachless relatives might actually have arrived at an energy-saving solution. He says that although the stomach is critical to many kinds of animal, the organ is "a fairly expensive organ to run". This perhaps explains why some animals have got rid of theirs.
Answer: digests the smaller fish in its body
[EX A]: Ryan Day ran the chemical tests in order to find out how the longtom _ .

[EX Q]: Article: Taste is such a subjective matter that we don't usually conduct preference tests for food. The most you can say about anyone's preference is that it's one person's opinion. But because the two big cola companies--Coca-Cola and Pepsi Cola are marketed so aggressively, we've wondered how big a role taste preference actually plays in brand loyalty. We set up a taste test that challenged people who identified themselves as either Coca-Cola or Pepsi fans: Find your brand in a blind tasting. We invited staff volunteers who had a strong liking for either Coca-Cola 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 guess-work could have accomplished. Getting all four samples right was a tough test, but not too tough, we thought, 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 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 tiredness, or taste _ , 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.
Answer: reveal which cola is more to the liking of the drinkers
[EX A]:
According to the passage the preference test was conducted in order to _ .
