Read the following article and select the best answer. Article: A small dog should be _ after eating a handful M&M's, at least according to conventional wisdom. But watching "Moose", a friend's five-pound Chihuahua, race around a living room after his sweet snack makes one wonder: Is chocolate truly poisonous to dogs? Dogs and humans have similar tastes. But unlike humans, our companions experience dangerous effects from eating chocolate --it can poison them and in some cases is fatal. Chocolate's danger to dogs depends on its quality. Chocolate is processed from the bitter seeds of the cocoa tree, which contain a family of compounds known as methylxanthines . This class of substances includes caffeine and the related chemical theobromine . Chocolate contains a significant amount of theobromine and smaller amounts of caffeine. These chemicals can cause a dog's heart to race up to twice its normal rate, and some dogs may run around as if "they drank a gallon of espresso ," according to Hackett. Dogs are capable of handling some chocolate, but it depends on the animal's weight and the type of chocolate it eats. Unsweetened baking chocolate contains more than six times as much theobromine as milk chocolate, although amounts vary between cocoa beans as well as different brands of chocolate. Less than four ounces of milk chocolate is potentially fatal for Moose and other small dogs. Around every confection-centered holiday -- Valentine's Day, Easter and Christmas -- at least three or four dogs are hospitalized overnight in the animal medical center at Colorado State. But in 16 years, Hackett has seen just one dog die from chocolate poisoning, and he suspects it may have had an underlying disease that made it more exposed to chocolate's heart -racing effect. Question: All of the following are true EXCEPT _ . - chocolate's danger to dogs depends on its quantity and quality - people buy lots of chocolate around Valentine's Day - an ounce of unsweetened baking chocolate is safe for Moose - there must be some theobromine or caffeine in espresso
an ounce of unsweetened baking chocolate is safe for Moose

Read the following article and select the best answer. Article: Although new laws have been passed in some American states to cut down on distracted driving, many accidents and deaths were still related with it, especially using cell phones while driving. Recently the Obama administration is considering disabling cell phones in cars, aiming to out down cell-phone-related road deaths. Transportation Secretaryy Ray LaHood, the nation's anti-distracted-driving supporter, said in an interview on November 18 that federal officials are looking at technology to disable cell phones inside cars. "I think it will be done," LaHood said."I think the technology is there and 1 think you're going to see the technology become adaptable in automobiles to disable these cell phones.We need to do a lot more if we were going to save lives." Also on Thursday, the transportation government started a new "Faces of Distracted Driving" video campaign that features people who have been killed or lost their loved ones because of inattentive drivers.The video features heartbreaking stories of children killed in crashes because of phoning or text messaging, and new videos are expected to be added every few weeks. A driver is four times more likely to crash while using a mobile phone.More than 5,500 people were killed last year by distracted drivers, and another 500,000 were injured.LaHood has said it is never safe to talk on a cell phone while driving, hands-free or not, because it can really cause distraction. Incidentally, a lot of people seem to agree with this viewpoint--a new research shows nearly two-thirds of Americans support a national ban on the use of cell phones while driving, even if the driver is using a hands-free device .But the research didn't ask how people feel about government-issued mobile phone scramblers or other disabling devices. Question: We can infer from the text that _ . - most people realize the harmfulncss of distracted driving - most people would like to choose hands-free devices while driving - the disabling devices in cars will be widely used if it is free - the writer is not sure whether disabling devices will be accepted by the drivers
(Answer)
the writer is not sure whether disabling devices will be accepted by the drivers

Read the following article and select the best answer. Article: Dr. Jack M. Gwaltney, Jr. a professor at the University Of Virginia School Of Medicine infected six student volunteers with virus, the most common cause of colds. A few days later, when they were coughing and sneezing, he gathered 37 more people and divided them into three groups. Group 1 members spent three days and nights in the same room with one of the infected students, separated by a screen so they couldn't touch one another. Group 2 sat around a table while an infected volunteer talked, coughed and sang to them. Group 3 held hands with an infected student for ten seconds, and then touched their own noses or eyes. Although most scientists at the time, the mid-70s, believed colds were spread by virus-laden droplets spread through the air when infected people coughed or sneezed, Gwaltney suspected physical contact might play an important role. Sure enough, of the 15 people who had touched a student volunteer, 11 became infected--compared with only one of those who had been sitting at the table, and none who had spent three days and nights together. "The best evidence we have is that hand-to-hand contact is the most efficient way of transmitting virus," says Gwaltney. The study was one of a series that helped establish Gwaltney's reputation as a leading authority. Dr. Robert Couch says, "It would not be inappropriate to call him Mr. Common Cold." When Gwaltney is asked how close scientists are to finding a cure, he replies: "If you mean 'get rid of', I don't think we're going to be able to do that with cold viruses any time soon. But if you look in the dictionary, you'll see that 'cure' is explained as a successful treatment. And we're not just getting more effective at treating the symptoms --we're getting at the root cause too. " Question: Mr. Common Cold is _ . - a newly-found virus - a nickname of respect to Dr. Gwaltney - a method to cure colds - a way by which the other scientists laughed at Dr. Gwaltney
a nickname of respect to Dr. Gwaltney
