Q: Read the following article and answer the question. Article: Every day it seems that people are coming up with new and innovative ways to use mobile devices like cellphones and smart phones. Researchers at Princeton University are looking for new ways to measure a person's sense of _ with mobile devices. To gain a better understanding of how cellphones and other mobile devices can measure our sense of happiness, the research team conducted a study that was published recently in the journal Demography. To gather data for their study, the team created an application for mobile devices using the Android operating system. Once the app was developed, the researchers invited people to download it and take part in their study. Over a three-week period, the research team was able to collect data from some 270 participants living in 13 countries. Participants came not only from the United States, but also from other nations like Australia, Canada, China, France, Germany, Israel, Japan, Norway, South Korea, Spain, Sweden and the United Kingdom. Over the course of the study, participants received occasional text questions from the researchers that asked "How happy are you?". Along with recording their response, the app used the mobile device's built-in GPS to keep track of the participant's location. The study participants were asked to rate their current state of happiness on a scale of zero to five. As they gathered data from the information collected through the application, the researchers then were able to create new methods that could help provide a better understanding of how our surroundings can influence our emotional well-being. The researchers learned that mobile devices can provide an effective way to quickly grab information that, because of today's active lifestyle, can be difficult to record. Being able to quickly grab this information was something the researchers felt was important. They said feelings and emotions that were recorded as they were happening were most likely to be more honest and precise than using other methods like writing down how they felt on a... Question: The best title of the passage is most likely to be "  _  ". Answer:

Q: Read the following article and answer the question. Article: Young people frequently say that they want to exercise, but they just can't find the time. The solution just might be in-office interval training. Recent studies show that very short but intense exercise rapidly builds and maintains fitness and health, even when the workout is only a few minutes long. Work the stairs You can complete an excellent, effective -- and very brief -- workout in an office stairwell, says Martin Gibala, a professor of kinesiology at McMaster University in Canada and an expert on interval training. For a study that he and his colleagues presented earlier this year, they asked 12 out-of-shape women in their 20s to warm up for two minutes by slowly walking up and down stairs in a campus office building. They completed three of these abbreviated stair workouts per week for six weeks. By the end, their aerobic fitness had improved substantially, the researchers reported, by about as much as if they had been running or cycling each week for hours. Fidget your way to fitness. Parents and teachers may once have urged you to sit still, but wiggling, tapping your toes, standing briefly, and otherwise fidgeting as much as possible at your desk is in fact good for your body. In one recent study, college students showed healthier blood flow in their lower legs if they fidgeted than if they did not. Even better, a 2008 study found that among office workers, those who frequently fidgeted burned as many as 300 calories more each day than those who resolutely stayed still. Question: What does the passage mainly want to tell us? Answer:
Answer: several ways to work out within short time

Q: Read the following article and answer the question. Article: While I was waiting outside my wife's office building for her to get out of work, I saw a beggar coming my way from across the parking lot. "I hope he doesn't ask me for any money," I thought. He didn't. He came and sat in front of the bus stop, but he didn't look like he could have enough money to ride the bus. After a few minutes he spoke. "That's a pretty car," he said, pointing to my car. He was ragged  , but he had an air of dignity about himself. I gave him a smile and continued cleaning my car. He sat there quietly as I worked. The expected asking for money never came. As the silence between us widened, it seemed that a voice inside me said, "Ask him if he needs any help." I was sure that he would say "yes", but I listened to the inner voice. "Do you need any help?" I asked. He answered in three simple but meaningful words that I shall never forget. We often look for wisdom in great men and women, and we expect it from those of higher learning and achievements. I expected nothing but a dirty hand from him, but he said three words that shook me. "Don't we all?" he said. I was feeling high, successful and important above a beggar in the street, until those three words hit me like a shot. Don't we all? I needed help. Maybe not for a bus fare or for a place to sleep, but I needed help. I reached in my wallet and gave him not only for a bus fare, but enough to get a warm meal and shelter for the day. Those three little words still ring true. No matter how much you have, no matter how much you have achieved, you need help, too. No matter how little you have, no matter how loaded you are with problems, even without money or a place to sleep, you can give help. Question: Which of the following is NOT TRUE? Answer:
Answer:
The beggar kept silent and didn't ask him for money.
