Researchers claimed that waitresses who wear red get up to 26 percent extra in tips than they would wearing other colors. However, the team finds that the sexes tip very differently--with the bigger tips coming only from male customers. No matter what color they wear, female diners will give the same kind of amounts for service every time. Yet men, whether they realize it or not, add anything between 15 and 26 percent more to a waitress in red than they would if it was the same waitress wearing a different color. The test was simple. Take 11 waitresses in five restaurants over a six-week period and ask them to wear the same kind of T-shirt every day but change the colors. Previous research has suggested waitresses could earn more if they acted charmingly or wore more make-up than their colleagues. But this study, by the Journal of Hospitality and Tourism Research, only changed the color of the T-shirt. Every other aspect from make-up to behavior remained the same. When wearing either black, white, green, blue or yellow T-shirts, the size of the tips from both male and female customers was almost _ . But when they wore red, the size of the tips went up by between 15 and 26 percent from male customers, yet stayed the same from female ones. A total of 272 restaurant customers were studied by researchers Nicolas Gueguen and Celine Jacob for the international journal of the tourism industry. Even as a T-shirt, it shows just how much the color red is thought, by men, to increase the physical and sexual attractiveness of woman, said the researchers. The researchers wrote: As red color has no negative effect on women customers, it could be in their interest to wear clothes at work. What is the main idea of the passage? A) People tip differently if waitresses wear different make-up. B) Waitresses who wear red get more tips than they would wearing other colors. C) Male customers are more interested in the red color. D) Red color has no negative effect on female customers.

Ques: Polar bears are born in dens on land and their mother stays with them for the whole winter without eating anything. The mother and the babies come out from the dens around March, _ from a long winter and must immediately go hunting to find food to stay alive. Now, the only hunting they know is to catch seals from floating ice in the open ocean. In March, polar bear mothers and babies have to swim from the land in Spitsbergen to the edge of the polar ice cap. Normally this is a short swim, since in March the polar ice cap is very close to the land, and the polar bears, and even the babies, are good swimmers. However, last year we saw that the polar ice cap had become smaller in size due to global warming. Swimming hundreds of miles, especially when they are hungry and have babies following them, is really hard, and many bears are dying because of starvation. The polar bear population in the Spitsbergen area was once threatened by hunters. In the 1970s, a ban on hunting was imposed and the polar bear population has been steadily increasing from just a few hundred to about 2,000 to 3,000. This was a great success story. However, now, because of global warming, the population is again in danger. If we do not stop making so much carbon dioxide, we will lose these beautiful animals forever. The polar bears are just one example of animals that have become endangered because of man's appetite for energy obtained by burning fossil fuels. All life on earth could be in danger unless we change our ways. What can we do? To reduce the amount of carbon dioxide in the air we must save and make energy without burning coal and oil. Instead, we can use the sun or the wind to generate electricity. We must also cut down on needless driving and turn off things that use electricity when we are not using them. In addition, we have to stop cutting down forests and start planting more trees. Why do the bears swim to the edge of the polar ice cap? A) To get back to the ocean. B) To catch seals for food. C) To get to a colder place. D) To teach their children how to swim.
