Read the article and select the best answer. Article: Two new studies suggest that modern running shoes could increase the risk of injuries to runners. One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week. The runners were observed on a treadmill machine . Sometimes they wore running shoes. Other times they ran barefoot . Researchers from the JKM Technologies company in Virginia, the University of Virginia and the University of Colorado did the study. They found that running shoes create more stress that could damage knees, hips and ankle joints than running barefoot. They observed that the effect was even greater than the effect reported earlier for walking in high heels. The study appeared in the official scientific journal of The American Academy of Physical Medicine. The other study appeared in the journal Nature. It compared runners in the United States and Kenya. The researchers were from Harvard University in Massachusetts, Moi University in Kenya and the University of Glasgow in Scotland. They divided the runners into three groups. One group had always run shoeless. Another group had always run with shoes. And the third group had changed to shoeless running. Runners who wear shoes usually come down heel first. That puts great force on the back of the foot. But the study found that barefoot runners generally land on the front or middle of their foot. That way they ease into their landing and avoid striking their heel. Harvard's Daniel Lieberman led the study. He says the way most running shoes are designed may explain why those who wear them land on their heels. The heel of the shoe is bigger and heavier than other parts of the shoe, so it would seem more likely to come down first. Also, the heel generally has thick material under it to soften landings. But the researchers do not suggest that runners immediately start running barefoot. They say it takes some training. And there can be risks, like running when your feet are too cold to feel if you get injured. The study was partly supported by Vibram,...

Read the article and select the best answer. Article: There was once a boy who hardly had any toys or money. Nevertheless, he was a very happy little boy. He said that what made him happy was doing things for others, and that doing so gave him a nice feeling inside. However, no one really believed him, they thought he was silly. He spent all day helping others, dispensing charity to the poorest, and looking after abandoned animals. Very seldom did he ever do anything for himself. One day, he met a famous doctor who thought the boy's case was so peculiar that he decided to investigate him. So, with a complex system of cameras and tubes, the doctor managed to record what was happening inside the boy. What he discovered was surprising. Each time the boy did something good, a thousand tiny angels gathered around the boy's heart and started tickling it. That explained the boy's happiness, but the doctor continued studying until he discovered that we all have our own thousand angels inside us. Unfortunately, he found that, as we do so few good things, the angels spend most of their time wandering about, bored. And so it was that the secret to happiness was discovered. Thanks to that little boy we now know exactly what we have to do to feel our hearts being tickled. Question: The famous doctor hopes to discover_. Options: A: what it is that makes the boy so happy B: what has gone wrong with the boy's heart C: whether the boy has a thousand angels inside D: why the boy never does anything for himself

Q: Read the article and select the best answer. Article: Phone Soap: Charge and Clean Your Phone You may charge your phone every day, but do you clean your phone as much? Whatever your hands touch, your phones touch. It has been discovered that some phones have 18 times more bacteria and viruses than any surface in a public restroom. So it probably won't surprise you that a 2011 University of London study found that one in six of our phones have bacteria and viruses on them--specifically, the bacteria called E. coli. The research on bacteria and viruses led to the invention of Phone Soap. It is not actually liquid like dishwasher soap. It is a phone charger that uses the electromagnetic radiation used in hospitals to kill 99.9 percent of bacteria and viruses, cleaning your phone while it charges. "There are really certain types of bacteria and viruses that we should not be in touch with, and they are really on our phones," says Wes Barnes, the Phone Soap co-founder. It all started while his cousin and co-founder, Dan LaPorte, was in his cancer research lab at college. "He realized he got the idea of getting rid of bacteria and viruses on the phones," said Barnes. "In the lab they used UV-C light for destroying them. He realized this would be the fastest, most powerful way to kill any bacteria and viruses living on electronic machines." Phone Soap looks like a little metal suitcase. Your phone rests in to charge and get cleaned at the same time. Instead of plugging your phone into the wall, you'd plug it into the Phone Soap charger box. The process only takes a few minutes but, Barnes says, "The idea is that you can leave it in there overnight if you want to keep charging. Reflective paint keeps the light completely around the phone so it cleans the phone fully." The co-founders spent 2013 finding the right companies and they started shipping the product in late November. By last week's International Consumer Electronics Show in Las Vegas, Phone Soap was all grown-up. Both co-founders have left their previous jobs and are selling Phone Soap nonstop. "We're... Question: According to the passage, Phone Soap _ . Options: A: takes a whole night to kill bacteria B: deals with bacteria with radiation C: is a kind of liquid like dishwasher soap D: has to be plugged into the wall to work
