I'm taking a test and have to guess the right answer to the question after the article. Article: Children who are raised in households with dogs during their first year of life may have a lower risk of asthma a few years later, a new study suggests. In the study, the researchers looked at early exposure to dogs and farm animals and the rate of asthma among about 276,000 school-age children in Sweden. Among the school-age kids in the study, those who had been exposed to dogs during their first year of life were 13 percent less likely to have asthma at age 6. The researchers said they don't know for sure what exactly may explain the relationship between early exposure to animals and a reduced risk of asthma."It might be due to a single factor, or more likely, a combination of several factors related to a dog ownership lifestyle or dog owners' attitudes, such as kids' exposure to household dirt and pet dust, time spent outdoors or being physically active,"Fall told LiveScience."As a parent in a dog-and-baby household, it is nearly impossible to keep everything clean, and maybe this is a good thing for your baby's future health." Currently, one of the main hypotheses that aim to explain the link between a lower risk of asthma and early exposure to pets is that"kids in animal environments breathe air that contains more bacteria and bacterial fragments, which actually could lower their risk of asthma,"she said. Previous research on having pets and the risk of asthma in kids has mixed results. For example, the results of a 2001 review of previous studies suggested that exposure to pets was linked to an increased risk of asthma in children. But a 2012 review suggested that exposure to pets, especially dogs, was tied to a decreased risk of asthma and allergies in childhood. "My take-home message from this study is that parents at this point do not need to worry about keeping their dog when expecting a baby for fear of asthmatic disease,"Fall said."I do want to be clear that this recommendation is valid only for families without a child already having allergies. If they already have a furred-animal-allergic... Question: What's the purpose of the passage? Options: A: To tell readers the finding of a study on children. B: To persuade parents to buy a pet for their children. C: To clarify some misconceptions about keeping a pet. D: To explain why keeping a pet is beneficial to children.

I'm taking a test and have to guess the right answer to the question after the article. Article: In the old days, children were familiar with birth and death as part of life. This is perhaps the first generation of American youngsters who have never been close by during the birth of a baby and have never experienced the death of a family member. Nowadays when people grow old, we often send them to nursing homes. When they get sick, we send them to a hospital, where children are forbidden to visit terminally ill patients - even when those patients are their parents. This deprives the dying patient of significant family members during the last few days of his and it deprives the children of an experience of death, which is an important learning experience. Some of my colleagues and I once interviewed and followed about 500 terminally ill patients in order to find out what they could teach us and how we could be of more benefit, not just to them but to the members of their families as well. We were most impressed by the fact that even those patients who were not told of their serious illness were aware of its possible result. It is important for family members, and doctors and nurses to understand these patients' communications in order to truly understand their needs, fears and fantasies. Most of our patients welcomed another human being with whom they could talk openly, honestly, and frankly about their trouble. Many of them shared with us their great need to be informed, to be kept up-to-date on their medical condition and to be told when the end was near. We found out that patients who had been dealt with openly and frankly were better able to deal with the coming of death and finally to reach a true stage of acceptance prior to death. Question: Children in America today are deprived of the chance _ . Options: A: to learn how to face death B: to visit their family members C: to look after patients D: to have access to a hospital

I'm taking a test and have to guess the right answer to the question after the article. Article: Have you seen a yellow-and-black salamander ? How about a scarlet frog? Scientists haven't spotted either species in more than 20 years. What happened to them? Are the creatures still out there, or are they extinct? Those are questions that scientists hope to answer. They recently set out around the world in search of those and other long-missing amphibians. An amphibian is an animal that spends part of its life in water and part on land. Frog, toads , and salamanders are amphibians. The experts are looking for about 100 species. They are searching at least 14 countries on five continents. They will look for the salamander in North America. They hope to find the scarlet frog in South America. They're also looking for species in Africa, Asia and Australia. Scientists are hopeful that they'll find the amphibians--and soon! If the creatures are out there, they may need help. Many amphibians are endangered. The animals face many dangers including pollution and diseases. People cut down the forests where they live. "If researchers can find the missing creatures, they might be able to figure out how to save them," explains expert Robin Moore. He began searching for the amphibians earlier this month. "This search will tell us a lot about how amphibians are doing," Moore told WR News. "I don't know what we will find, but that makes the search even more exciting." Lost in the Wild Scientists' hunt for missing amphibians is under way. Read about some of the species they hope to find. Turkestanian salamander This salamander is a mystery to scientists. Experts found a few of them more than 100 years ago, but none have been seen ever since. Gastric brooding frog Experts first discovered this frog in 1914 in eastern Australia. It may be extinct because of disease and habitat loss. Rio Pescado stubfoot toad Last sighting: 1995, in South America Scientists hope to find this spotted toad in rivers and rainforests in Ecuador. The animal faces threats including pollution and disease. Question: Why do the scientists want to find the missing amphibians? Options: A: Because they want to rescue the missing amphibians. B: Because they want to set up a scientific program. C: Because they want to do a scientific research on the missing amphibians. D: Because they want to publish a report about the missing amphibians on WR News.
