The U.S. Centers for Disease Control and Prevention says the person also might repeat some behaviors and not want change in their daily activities. Some people with the condition need a lot of help. Others need less. CDC officials say autism affects one in every 68 children in the United States. More boys than girls are believed to have the condition. But the number of cases appears to be growing. It is unclear whether the growing number shows a real increase or comes from more knowledge about this disorder. Symptoms of autism Common signs of autism include trouble making eye contact and a delay in learning how to speak. Some people with severe autism never learn how to talk. Many people with autism also have difficulty understanding facial expressions and the feelings of others. They also have trouble making friends of the same age. Doctors have learned how to recognize autism, but much is still unknown about its causes. Researchers at Harvard University have come closer to finding answers. They found that women exposed to the highest levels of fine particulate air pollution late in their pregnancies are two times more likely to give birth to a child with autism. The findings appeared in Environmental Health Perspectives -- a publication of the National Institute of Environmental Health Sciences. The study found that the women who were around high levels of fine particulate matter air pollution were at highest risk of having an autistic child. The increased risk of these women was two times that of women who lived in areas with low levels of fine particulate pollution. The researchers found that the timing of exposure to pollution was important. They found no increased risk of autism in children whose mothers were around high levels of pollution before becoming pregnant. And the study found air pollution does not seem to increase the risk of children developing autism after they are... Question: What can pregnant women do _ ? Options: A: they should go running in a street B: they should stop smoking C: they should be in extremely polluted cities during pregnancy D: they should avoid air pollution as much as possible

Read the article and select the best answer. Article: Psychologists have known that what's going on inside our head affects our senses. For example, poorer children think coins are larger than they are, and hungry people think pictures of food are brighter. Professor Remi Radel wanted to investigate(look into) how this happens -- whether it's right away, as the brain receives signals from the eyes, or a little later, as the brain's higher-level thinking processes get involved. Radel chose 42 students and each student was told to arrive at the lab at noon after three or four hours of not eating on the day of the test. Then they were told there was a delay. Some were told to come back in 10 minutes; others were given an hour to get lunch. So half the students were hungry when they did the experiment and the other half had just eaten. For the experiment, the participant looked at a computer screen. One by one, 80 words flashed on the screen. A quarter of the words were food-related. After each word, the person was asked how bright the word was and asked to choose which of two words they'd seen -- a food-related word like gateau (cake) or a neutral word like bateau (boat). Hungry people saw the food-related words as brighter and were better at identifying food-related words. Because the word appeared too quickly for them to be reliably seen, this means that the difference is in perception , Radel says--it's not because of some kind of processing happening in the brain after you've already figured out what you're looking at. "This is something great to me, that humans can really realize what they need or what they hope for, to know that our brain can really arrange for our motives and needs," Radel says. "There is something inside us that selects information in the world to make life easier." Question: Which of the following is true about the experiment? Options: A: The students should stare at the words in the book. B: Each word appeared slowly in order that the participant could read it exactly. C: After each word flashed on the screen, the person was asked to finish two tasks. D: On the day of the test, all the students were very hungry because of the delay of their lunch.
