Question: Write a multi-choice question for the following article, with the given choices and 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,... Options: A The way that we run by landing on the front or middle of our foot could avoid damaging our heel. B We should start running barefoot in no time. C Running in modern running shoes could cause more serious effects than running in high heels. D We won't be injured if we run barefoot. Answer: A The way that we run by landing on the front or middle of our foot could avoid damaging our heel. Question:

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Baby girls make their way directly for dolls as soon as they can crawl, while boys will head for the toy cars, a study has shown. The findings, the first to show differences in very young babies, suggest there is a biological basis to their preferences. Psychologists Dr Brenda Todd from City University London carried out an experiment involving 90 infants aged nine months to 36 months. The babies were allowed to choose from seven toys. Some were stereotypically boys' toys - a car, a digger, a ball and a blue teddy. The rest were girls' toys: a pink teddy, a doll and a cooking set. They were placed a meter away from the toys, and could pick whichever toy they liked. Their choice and the amount of time they spent playing with each toy were recorded. Of the youngest children (nine to 14 months), girls spent significantly longer playing with the doll than boys, and boys spent much more time with the car and ball than the girls did. Among the two-and three-year-olds, girls spent 50 percent of the time playing with the doll while only two boys briefly touched it. The boys spent almost 90 percent of their time playing with cars, which the girls barely touched. There was no link between the parents' view on which toys were more appropriate for boys or girls, and the children's choice. Dr Brenda Todd said: "Children of this age are already exposed to much socialization. Boys may be given 'toys that go' while girls get toys they can care for, which may help shape their preference. But these findings agree with the former idea that children show natural interests in particular kinds of toys. There could be a biological basis for their choices. Males through evolution have been adapted to prefer moving objects, probably through hunting instincts , while girls prefer warmer colors such as pink, the color of a newborn baby."

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: A "lost tribe" that reached America from Australia may have been the first Native Americans, according to a new theory. If proved by DNA evidence, the theory will break long established beliefs about the southerly migration of people who entered America across the Bering Strait, found it empty and occupied it. On this theory rests the belief of Native Americans to have been the first true Americans. They would be classified to the ranks of escapee, beaten to the New World by Aboriginals in boats. To a European, this may seem like an academic argument, but to Americans it is a philosophical question about identity, Silvia Gonzales, of Liverpool University said . Her claims are based on skeletons found in the California Peninsula of Mexico that have skulls quite unlike the broad Mongolian features of Native Americans. These narrow-skulled people have more in common with southern Asians, Aboriginal Australians and people of the South Pacific Region. The bones, stored at the National Museum of Anthropology in Mexico City, have been carbon-dated and one is 12,700 years old, which places it several thousand years before the arrival of people from the North. "We think there were several migration waves into the Americas at different times by different human groups," Dr. Gonzales said. "The timing, route and point of origin of the first colonization of the Americas remains a most contentious topic in human evolution." But comparisons based on skull shape are not considered conclusive by anthropologists, so a team of Mexican and British scientists, backed by the Natural Environment Research Council, has also attempted to take out DNA from the bones. Dr. Gonzales declined yesterday to say exactly what the results were, as they need to be checked, but indicated that they were consistent with an Australian origin. Options: A North Asia B Australia C South Pacific D South Asia Answer: A North Asia Question:
