TASK DEFINITION: In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.
PROBLEM: Article: If you think by examining someone's facial expressions you can judge if he has good or bad luck in the stock market, think again. A study published in the journal, Science, has shown that body language provides a better signal in judging whether the observed subject has just gone through an intensely positive or negative experience. To test highly intense faces, Dr. Hillel Aviezer and his colleagues presented test groups with photos of dozens of highly intense facial expressions in real-life situations. In one study, they compared emotional expressions of professional tennis players winning or losing a point. To discover exactly how people view images, the researchers showed different editions of the pictures to three groups of participants: 1 ) the full picture with the face and body;2) the body with the face removed; 3) the face with the body removed. Remarkably, participants could easily pick the losers from winners when they judged by the full picture or the body alone, but they only had a 50:50 chance of being right when judging by the face alone. Strangely, the participants .who viewed the full image believed that it was the face, not the body, that revealed the person's emotions. In an additional study, the researchers performed the same series of tests, asking viewers to examine a wider range of real-life intense faces. Again, viewers were unable to tell faces in positive situations from negative situations. The researchers also "planted" faces on bodies expressing positive or negative emotions. Sure enough, the researchers discovered that the emotion of the same face on different bodies was determined by the body on which it appeared. "These results show that when emotions become extremely intense, the difference between positive and negative facial expressions no longer seems clear," says Aviezer. "The findings challenge classic behavioral models, in which the boundary between positive and negative emotions is clear." Aviezer adds, "The results may help researchers understand how body and facial expressions interact during emotional situations. For example, individuals with autism may fail to recognize facial expressions, but if trained to read important body language signs, their performance may significantly improve."
Answer: The participants were divided into three groups.

SOLUTION: What can we learn from the first study?

PROBLEM: Article: Researchers who helped discover a new species of Mexican butterfly are offering to sell the naming rights to raise money to fund more research. Co-discoverer Andrew Warren is hoping to raise at least $50,000 by auctioning off the rights to name the 4-inch "owl eye" butterfly, which lives in Sonora, a Mexican state bordering Arizona. "That would support at least two years of research for our team down in Mexico," Warren said. "Money goes a long way down here in Mexico." According to the scientific tradition, discoverers of a new species have the say in naming it. In recent years, some discoverers have auctioned off their naming rights to raise money. Warren said the amount being sought for the butterfly is not out of the question, noting that naming rights for a new monkey species brought in $650,000 two years ago. A group of 10 new fish species that went on the naming auction block at the same time earlier this year brought in a total of $2 million. The butterfly discovered by Warren and researcher George Austin ranges as far north as Mexico. The butterfly was actually in a collection, misidentified as an example of another new species, at the McGuire Center for Lepidoptera and Biodiversity at the Florida Museum of National History in Gainesville, said Warren. They soon began the hard process of determining that it was indeed a "new" model of butterfly. After checking photos and comparing it with other known species, they determined it was a separate species.
Answer: Near the US-Mexico border.

SOLUTION: Where did the researchers discover the new species of butterflies?

PROBLEM: Article: A recent survey in the United States showed that the average family spent more money on its pets than on its children. Although rather shocking, it should not surprise anyone who has seen the doggy parlors where loved pets rest. Are Americans unique in treating their little friends in this way? No, the English, too, pay more attention to their pets. This can clearly be seen when we look at pet foods, which often contain more vitamins than human food. They certainly cost much. Last year the British public spent two hundred million pounds on pet food alone, to say nothing of veterinary bills or animal furniture. It is difficult not to feel angry about this when considering what the same amount could do for victims of starvation and poverty, so it is not unusual for me _ when I read an old man left all his money to his dog instead of his children. There are a variety of reasons why I find pets-raising alarming. They cause physical problems. An example of this is New York where they have great difficulty getting rid of the mess that dogs leave on the streets. Many people find this funny, but in a number of large cities it is a major problem. Animals can cause disease, too. It is the threat of rabies -- a disease with no known cure. Another problem is the carelessness of pet owners. Most little children want a dog or a cat, and they continually push their mothers and fathers until they get one. It is only when the "sweet little thing" has been brought home that the parents realize how much time and money must be spent on "Rover" or "Bonzo". Then they just abandon it. As a result, they are allowed to run free. English farmers lose hundreds of sheep a year, killed by someone's pet and you must have read of children being hurt by some pets of their own. Lastly, I would only suggest that we have got our priorities wrong and that something should be done about it. In my view, it's time we stopped being sentimental about pets. I can see no reason why we should get upset when animals are cut up for medical experiments. This will lead us to discovering cures for serious human diseases, then I say, "keep cutting!"
