Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Autism spectrum disorder is a developmental disability. People with autism have trouble communicating and with social skills. 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's the main idea of the passage _ ? Options: A: what is autism spectrum disorder B: the reasons of autism C: autism and air pollution D: how to treat autism
Answer: C

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Scientists have tried to come up with biological explanations for the difference between boys and girls. However, none were believable enough to explain the general picture. As one scientist points out, "There are slight genetic differences between the sexes at birth which may affect the subjects boys and girls choose. But the difficulty is that by the time children reach school age, there are so many other effects that it is almost impossible to tell whether girls are worse at science and maths, or they've been brought up to think of these subjects as boys' 'territory' ". Statistics show that in mathematics, at least, girls are equal to boys. A recent report suggests that girls only stop studying mathematics because of social attitudes. One of the reports' authors says, "While it is socially unacceptable for people not to be able to read and write, it is sill acceptable for women to say that they are 'hopeless' at maths. Our research shows that, although girls get marks which are as good as the boys' , they have not been encouraged to do so." The explanation for the difference, which is very clear during the teenage years, goes as far back as early childhood experiences. From their first days in nursery school, girls are not encouraged to work on their own or to complete tasks, although boys are. For example, boys and not girls, are often asked to 'help' with repair work. This encouragement leads to a way of learning how to solve problems later on in life. A further report on maths teaching shows that teachers seem to give more attention to boys than to girls. Most teachers who took part in the study admitted that they expect their male students to do better at mathematics and science subjects than their females students. All of this tends to encourage boys to work harder in these subjects, gives them confidence and makes them believe that they can succeed. Interestingly, both boys and girls tend to regard such 'male' subjects like mathematics and science as difficult. Yet it has been suggested that girls... Question: According to scientific studies, girls_. Options: A: are poorer at maths B: avoid maths because of social reasons C: are afraid of maths because they are the weaker sex D: can't learn maths as well as boys
Answer: B

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: New Zealand Education Compulsory Education Compulsory education starts at age 5 and ends at age 16. Class Size The number of students in a class is 30 students. Classrooms Students from Years 5-8 stay in the same classroom for most subjects and move to other classrooms only for specific subjects. In Year 9, students take some courses With their homeroom class and some _ classes with students from different classes. Starting from Year 10, students no longer stay in the same classroom most of the time. They go to different classes according to their own choices and abilities. Term Dates A school year starts in January and ends in December. There are four terms in a year. Each term is about 10 weeks. Class Schedule School starts at around 8:30 and ends at 15:15. There are only five periods a day and a period is about an hour long. In the morning, around 10:30, there will be a 20-minute break when students usually have some snacks during this time. There is a lunch period at around 12:40 for about an hour. Teachers Teachers have to teach students of different year level at the same time. Most teachers teach students from at least three to four different year levels. Besides, quite a number of teachers teach more than one subject. This is because the fact that many courses are optional. Question: When you are in your 10th school year, you may. Options: A: choose and take some optional courses with your homeroom class B: stay with your classmates in the same classroom for all the subjects C: have both required and optional classes with the same classmates D: choose different classes according to your own choices and abilities
