Q: "If you can answer three questions," the dog said, "you can wear the magic shoes." Tommy looked up and down the deserted street. "Did you ... say something?" "That's right. Didn't you hear me?" It was a gruff voice, with just a trace of an English accent, and it was definitely coming out of the dog. "You're a dog." In fact it was a huge, fat bulldog, with big flaps of skin hanging off the sides of its face. From where it sat, on the front steps of the abandoned motel, it looked Tommy straight in the eye. "That's correct," the dog said. Tommy stared hard at the dusty windows of the motel office. "This is a trick, right? There's a TV camera back there and you want to make me look stupid." "No tricks, Tommy. Just three questions." "C'mon," Tommy said. He deepened his voice. "Sit up." The dog stared at him. "Roll over. Play dead." "Cut the crap, Tommy. Do you want the shoes or not?" "Let me see 'em." The dog shifted its weight to one side, revealing a battered pair of red Converse All-Stars. "Yuck," Tommy said. "Those are gross." "Maybe," the dog said, "but they're magic." "What are the questions?" "Which of the following presidents died in office? Lincoln, McKinley, F.D.R.?" "C'mon. They all did. That's the same dumb question they use when they're trying to sell you a free portrait on the telephone." "Which weighs more, a pound of feathers or a pound of lead?" "They both weigh a pound. This is stupid. Next you're going to ask me who's buried in Grant's Tomb." The dog narrowed its eyes. "Have you done this before?" "Ulysses S. Grant," Tommy said. "Lemme see the shoes." They were just his size and felt pretty good, even though they were scuffed up and the metal things were gone out of the side vents. "I don't feel any different," Tommy said. "You need the shoes to look for the treasure," the dog said. "What treasure?" "When you're wearing the shoes, you can open the doors of the motel rooms." According to the above context, answer the following question. How does Tommy feel about the dog talking to him? | OPTIONS:
- He would be president
- not enough information
- He would receive a free portrait
- that he was being tricked
A: that he was being tricked

Q: Cooking food is something we have done since the first caveman threw a mammoth steak on the fire. While it is true that cooking does cause chemical changes in food and a loss of some nutrients, it is a clear case of being alert and not alarmed. Every time we cook food, there is some degree of nutrient loss. Exposing food to heat, oxygen or light alters the nutrients found in food. It is not all bad news though because cooking food also has its advantages. Cooking food can increase its digestibility, meaning you will get more nutrients out of it. And even though there may be less of some nutrients from cooking, it is swings and roundabouts as the availability of certain phytonutrients increases. And of course, let's not forget that heating food kills some of the nasty microbes that can cause food poisoning. The principle behind a raw food diet is that cooking food destroys the natural enzymes and nutrients that would otherwise give us optimal health and control body weight. A raw food diet is almost entirely plant-based and includes fruits, vegetables, nuts, seeds, grains, vegetable oils and juices in their natural uncooked state. Now on the pro side for a raw food diet, it means if you are currently eating a lot of processed food, then switching to raw food will be a clear nutritional win. So that gets a big tick. Unquestionably, there are many benefits to eating plenty of fruits and vegetables. These foods are high in nutrients and fibre and low in kilojoules. But is raw superior to cooked? A review of 28 research studies found eaters of both cooked and raw vegetables had a lower risk of cancer compared to people who did not eat many vegetables in the first place. Where the science gets murky is the claim that raw food is better because cooking destroys the enzymes found in plants. It is 100 percent correct that cooking will do this. But so too does digestion. Few enzymes survive their trip through the hydrochloric acid spa bath in the stomach. And those plant enzymes are essential only to the plants. The... According to the above context, answer the following question. Foods lose nutrients: | OPTIONS:
- when they are exposed to oxygen
- when they are digested
- not enough information
- when they are cooked
A: when they are cooked

Q: Have you ever wondered whether it's worth your while to encourage an older person to start exercising? In 2014, the top-notch journal JAMA published the results of a fantastic research project: a study in which 1635 sedentary older adults (aged 70-89) were assigned to get either a structured exercise program, or a program of "successful aging" health education. The researchers called it the Lifestyle Interventions and Independence for Elders (LIFE) study. (You can read the full study here.) During the LIFE study, the two groups were followed for a little over 2.5 years. And by the end of the study, guess which group of volunteers was more likely to still walk a quarter of a mile (without a walker)? That's right. When it came to avoiding "major mobility disability" which the researchers defined as becoming unable to walk 400 meters or more a structured exercise program was better than a program of healthy aging education. Specifically, the researchers found that 30% of the exercisers experienced a period of major disability, compared to 35.5% of the seniors enrolled in the healthy aging education program. This is a very encouraging finding! That said, it's also a bit sobering to realize that even with exercise, almost 1 in 3 older adults experienced a period of limited mobility, of which half lasted 6 months or more. In this post, I'll share some more details on this study, because the results provide a wonderful wealth of information that can be helpful to older adults, family caregivers, and even geriatricians such as myself. Want to know how often the exercisers experienced "adverse events"? (Hint: often!) Wondering just what the structured exercise program involved? (Hint: more than walking!) Let's dig into the details! At the end of this post, I'll share my list of key take-home points for older adults and family caregivers. Who were the study volunteers? Whenever you read about a research study, it's important to understand how the study volunteers compare to the older adults in *your* life. One of... According to the above context, answer the following question. How many of the researchers were considered elderly people? | OPTIONS:
- None
- Several
- Few
- not enough information
A: not enough information
