Read the following article and select the best answer. Article: Beautiful people are indeed happier,a new study says,but not always for the same reasons. For handsome men,the extra kicks are more likely to come from economic benefits,like increased wages, while women are more likely to find joy just looking in the mirror. "Women feel that beauty is naturally important," says Daniel Hamermesh,a University of Texas at Austin labor economist and the study's lead author. "They just feel bad if they're ugly." Hamermesh is the acknowledged father of pulchronomics, or the economic study of beauty. It can be a dangerous job. He once made angry an audience of young Mormon women, many of whom wished to stay home with future children, by explaining that homemakers tend to be less attractive than their working-girl peers . "Since beautiful women tend to be paid more,they have more motivation to stay in the work force," he says. The pursuit of good looks drives several huge industries--in 2010, Americans spent $845 million on face-lifts alone--but few economists focused on beauty's financial power until the mid-1990s,when Hamermesh and his colleague, Jeff Biddle of Michigan State University, became the first scholars to track the effect of appearance on earnings potential for a large sample of adults. Like many other desirable commodities , "beauty is rare," Hamermesh says, "and that rareness commands a price." A handsome man is estimated to make 13 percent more during his career than a "looks-challenged" peer, according to calculations in Hamermesh's recent book, Beauty Pays. Interestingly, the net benefit is slightly less for pretty women, who may make up the difference by trading on their looks to marry men with higher earning potential. And some studies have shown that attractive people are more likely to be hired in a recession . Hamermesh argues that "there's not much we can do to improve our pulchritude ". There are even studies suggesting that for every dollar spent on cosmetic products,only 4 cents returns as salary--making lipstick a truly awful investment. _ . One... Question: Which of the following is right according to the passage? - Handsome men are happier because they can make profits from their pulchritude. - House wives are usually less beautiful and thus less motivated than their working peers. - Beauty's financial power has long been noticed historically as a most desirable commodity. - Beautiful women usually make more as they can trade their looks to wealthy and handsome men.
Handsome men are happier because they can make profits from their pulchritude.

Ques: Read the following article and select the best answer. Article: Animal experts in Croatia say a bear has learned how to trick people to let him in by knocking at the door. They believe the 220- kilogram brown bear probably learned the trick while nudging a door to get it to open. Experts have a guess that the nudging was mistaken by the owners for knocking and that the bear, pleased by the result, repeated the trick. The Loknar family from Gerovo in western Croatia said the bear had knocked at their door three times and they were now refusing to answer the door. ''We jumped out of the window as he came in through the door and went into the kitchen to take some food for the first time." Mum Nevenka Loknar told a reporter from a local newspaper. "I opened the door and saw him standing there and I didn't believe my eyes at first, then I ran for it as he walked in as if _ was the most normal- thing in the world." Bears are a common thing in the woods around here, but no one has ever heard of a bear that knocks at the door. Mum Nevenka Loknar said, "The bear is so intelligent. It's incredible. We've tried to put up lots of obstacles to stop him coming in, like a wire fence but he still gets through. I wouldn't be surprised if he knew how to use wire cutters." Question: It is _ in Gerovo that a bear knocks at the door. - unusual - a troubling problem - common - an exciting experience
Ans: unusual

Question: Read the following article and select the best answer. Article: Dogs have long been used to find explosives and drugs.Now,a new study shows that man's best friend can also help to find lung and breast cancer,researchers report in integrative Cancer Therapies.The findings show that trained ordinary household dogs can detect early--stage lung and breast cancers by smelling the breath samples of patients. Researchers have found that cancer cells send out molecules different from those of healthy ones,and that might be sensed by smell by the highly sensitive dog's nose. For the study,five dogs were trained by a professional instructor to respond differently to breath samples of healthy and cancer patients."The dogs learned to sit or lie down in front of cancer patient samples and to ignore control samples through the method of food reward," McCulloch explained. After a period of training,researchers tested the animals'ability to distinguish cancer patients from controls.The animals were given breath samples from 55 patients with lung cancer,3 1 with breast cancer and 83 healthy controls who were not included in the original training period. McCulloch's group found that the dogs were able to correctly distinguish the breath samples of cancer patients from those of the control subjects in about 90 percent of the cases.The dogs were also able to detecting early-stage lung and breast cancers. "These results show that there is hope for early detection,"McCulloch said.The re-searches are planning to conduct further studies on the breath composition of cancer patients to possibly design an electronic device that can do the dogs'job."A dog's nose is so powerful it can detect odors 10 000 to 100 000 times better than a human nose can.I hope people will be interested in doing this research,"McCulloch added,"It shows that there is definitely something out there." Question: McCulloch and his group used_in their research. - 10 dogs and 55 people - 5 dogs and 86 people - 10 dogs and 83 people - 5 dogs and 169 people
Answer:
5 dogs and 169 people
