You might watch and laugh when your dog chases its tail because it looks cute. But did you know that, even though it might appear like a fun game, it could mean your pet is sick? Researchers have found that if a dog runs after its tail, chases cars and barks at flies that are not there, it may have obsessive compulsive disorder (OCD, ). In fact, OCD is even more common among humans. The symptoms are varied: some people check and recheck the locks before they go out; others are extremely afraid of germs and have to wash their hands many times a day. English soccer star David Beckham, for example, cannot stand odd numbers of items in his fridge. So if he has three cans of drink he will throw one out, according to his wife Victoria. Hoping to better understand OCD in humans, a team of scientists from the University of Helsinki, Finland, studied 368 dogs, including those that chase their tail for several hours daily or a few times a month, according to Sciencedaily.com. They also examined dogs that had never chased their tails. Scientists took the dogs' blood sample and asked their owners some questions about their pets' daily life. Findings showed that among all kinds of dogs, bull terriers and German shepherds were likely to chase their tails, which led scientists to believe that genes can cause OCD. Diet also plays a part. It was found that dogs that eat food with certain vitamins and minerals chased their tails less. "Interestingly, there are indications that vitamins and minerals are helpful in human OCD treatment," said researcher Katriina Tiira. Moreover, tail-chasing is often found among dogs that were separated from their mothers too early or ones that didn't receive enough care. They are also more likely to turn out to be shyer and more afraid of loud noises at a young age. The study can help us understand the causes of OCD in humans. "Dogs share the same environment with humans, and large animals are physiologically close to humans," said Hannes Lohi, leader... Options: A Genes. B Diet. C The way they are brought up. D The time they spend with their owners. Answer: D The time they spend with their owners. Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Alaska polar bears are losing their fur and U.S. Geological Survey scientists don't know why. In the past two weeks, nine of 33 bears checked by scientists in the southern Beaufort Sea region near Barrow were found to have alopecia -- loss of fur, said Tony DeGange, chief of the biology office at the USGS Science Center in Anchorage. Three of four bears inspected Thursday near Kaktovik showed the symptoms as well. Scientists have been collecting blood and tissue samples from the suffering bears, but they do not know the cause or the significance of the outbreak, the Anchorage Daily News reported. "Our data set suggests that this is unusual but not unprecedented," DeGange said. Ten of 48 bears checked by the team in 1998-1999 had a similar condition, he said. In a long-standing project, the USGS has sent polar bear research teams to the area since 1984. The teams track and examine the bears to help determine their general health and habits. This year they saw their first bear with hair loss on March 21. The team will end up this year's operations in May when the sea ice becomes too dangerous for safe travel. "We took biopsies in 1999 and couldn't establish a causative agent for the hair loss then," DeGange said. "But now we have this unexplained death event going on with seals . And they haven't been successful in figuring out what caused the seal deaths. Is it just a matter of coincidence or is it related? We don't know." In December 2012, the National Oceanic and Atmospheric Administration declared an "unusual death event" based on a number of ringed seals found on beaches on the Arctic coast of Alaska during the summer. Dead and dying seals were found to have hair loss and skin sores. Affected seals were later observed in Canada and Russia. Options: A To send polar bear research teams to where the bears live. B To track the bears' route and give them physical examination. C To find out the bears' physical condition and living habits. D To search for the cause of the bears' loss of fur and solutions. Answer: C To find out the bears' physical condition and living habits. Question:

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Nutrition influences not only students' grades at school but their growth and development. Improper nutrition is one of the causes of childhood obesity. What can you do to help your child avoid childhood obesity? My first piece of advice is to look in your fridge. What are you buying at the grocery store? Think about it: if you don't buy junk food or snacks, your kids won't eat them at home. Now if you're like me -- both of your kids are at school, you'll know you can't police them every second of the day. This is the time when you'll need to talk to your children about their food choices. If you don't know the right food choices, there are so many free resources on-line to guide you. Try new things. I was very surprised to find out my 4-year-old daughter likes balsamic vinegar -- she calls it the "black sauce". She likes to have it with tomatoes and cucumbers. You just never know what your kids might like. Don't get stressed if you can't always prepare something healthy. You may sometimes leave the house and forget to take something out for dinner, or you are running late and there's no time to cook before you have to take one of the kids somewhere. However, you can still make healthy choices while dining out. Many of the fast food restaurants offer fruit and milk instead of soda. I like to buy organic frozen pizzas from the organic market -- for a quick dinner solution . All the ingredients are natural. What I do is to serve the pizza with something raw: lettuce, cucumbers, tomatoes, or fruit to try to give the kids something healthy with that meal. In closing, take baby steps. Don't try to change your family's eating habits in one go, or you'll go nuts. Options: A make sure their fridge is full of food. B teach their children how to eat healthily C check their children's grades at school D provide their children with their favorite food Answer: B teach their children how to eat healthily Question:???
