Article: Can dogs help with OCD? 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... Question: The English soccer star David Beckham is mentioned in the article to _ . Yes or no, is the answer "give an example of the symptoms of OCD"?

Article: When you think of environmental problems you probably think of pollution, but the poaching of wild animals is one, too. Poaching has worried environmentalists for years and, despite laws, this terrible crime has yet to be stopped. Poaching is a serious problem, especially in Africa and Asia. This crime is done for commercial profit , meaning hunters kill animals illegally and sell their most worthy parts. Although poachers usually hunt tigers, elephants and rhinos, they kill sharks and whales, too. This illegal hunting has led to decreasing populations of many species. Many nations have banned poaching, but enforcement is difficult. The small number of police officers trained to deal with this creates an unfair advantage for poachers. Poachers usually kill animals for only one product: tigers are killed for their striped fur, elephants their ivory tusks and rhinos their large horn. The bodies of the animals are left to rot. Sharks' fins are cut off and their bodies thrown back into the ocean. Without fins they can't swim and will die. The illegally obtained fins are used to make shark fin soup. The laws that "protect" animals are no more than pieces of paper. The current poaching bans need better enforcement, and I have a plan. The number of enforcers needs to be increased so that there are enough to watch the herds and make sure poachers can't shoot the animals. The reserve parks in Africa should become a huge zoo so that the animals can move but within a fenced area. Another idea is to build a concrete enclosure instead of fences. Watchtowers could be constructed so enforcers can monitor a wide variety of poacher targets. This may not completely end the problem, but it would slow it down. Poaching is a serious problem and a criminal act. The effects of poaching will be felt for centuries to come, and if there are any still alive, the only place to see animals might be in a zoo. Question: The purpose of this passage is to _ . Yes or no, is the answer "provide some suggestions on banning poaching"?
No

Q: Article: A recent report says we spend an average of two hours and 40 minutes each day looking at a smartphone. That doesn't mean making calls, but using apps and browsing the Web. Spend that amount of time staring at anything. Checked our email in a restaurant, shared a picture of the food when it arrived, or checked a fact during a conversation only to be drawn into reading more instead of contributing verbally. It's no secret our lives are being affected by our obsession with smartphones. However, never before has this phenomenon been displayed so vividly as in the short YouTube film I Forgot My Phone. Despite only being online for a few days, it's already been viewed more than 10. 5 million times. Ironically, YouTube's statistics show that the site gets a billion views per day from mobile devices, so a lot of those people watched it on their phone. The short film, written by and starring actress Charlene deGuzrnan, shows groups of people in various social situations, the majority of which are completely attracted by their phones instead of the world around them. It's depressing because we' ve all seen it, and sad because to a certain extent, we all do it. Question: By mentioning the YouTube's statistics, the author wants to Yes or no, is the answer "confirm the YouTube film's realitv"?
A: No

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. Question: This passage is written mainly to _ Yes or no, is the answer "give parents some healthy eating tips"?
**Answer**
No
