Question: Read the article and select the best answer. Article: If your mother told you to eat carrots so you'd be able to see in the dark, she was right. It turns out that feeding kids carrots is just one of a number of things to keep eyes healthy. Other things include regular eye exams, and sunglasses or hats are also very helpful, experts say. While eye disease is sometimes hereditary , some are still preventable , said Dr. Ron Weber, an Atlanta-based ophthalmologist. For example, nearsightedness, "not only has a genetic component but is also influenced by how kids use their eyes during childhood," he told Reuters Health by phone. He said that extended close work, such as reading, has long been thought to cause nearsightedness. Recent support has come from a study in which people with a higher level of education were more likely to have nearsightedness, because they spend more time reading or working on computers. Another study showed that children who spend more time outdoors are less likely to become nearsighted. But these findings don't mean kids should be stopped from reading or working on the computer. Instead, Weber suggests, make sure a child's environment is bright enough while they are doing close work. Parents should also help kids get into the habit of holding their reading material at the perfect distance - about 18 to 22 inches, he said. Finally, taking a break every five minutes or so, to let the eyes relax and focus on an object in the distance, will also help. One of the most important things a parent can do to help _ eye disease and vision problems is to make sure their child gets regular eye exams, beginning early in life. "The majority of vision problems in children are preventable and treatable," said Dr. Ida Chung. Question: Which can be the BEST title for this passage? Options: A: Eating carrots B: Eye disease C: How to keep eyes healthy D: The importance of eye health.

Question: Read the article and select the best answer. Article: For thousands of years, people have used plants to make medicines. They used different parts of the plants --the roots, the leaves, the flowers, and the bark . Today, doctors have rediscovered more medicinal values of some plants. Let's look at some examples. Foxglove is a common plant. People have used it to make the heart slow down. Recently scientists have developed another drug from it. This new drug helps prevent other heart problems. In some areas, _ has been a problem. Scientists have learned that the bark of a South American tree, the cinchona, can be made into a drug to prevent malaria. For a long time, the Chinese have known that a special plant, wormwood, can also fight malaria. Scientists have been working with it to develop new drugs against malaria. In Germany, some scientists studied garlic for four years. They found that it helps prevent the build-up of plaque because too much plaque is bad for health. This very common plant continues to be studied. As we know, there are about 250,000 kinds of flowering plants in the world. Scientists have only studied little more than one percent of plants for their medicinal value. Maybe medicines for AIDS and cancer will be made from the other 99 percent.
