I'm taking a test and have to guess the right answer to the question after the article. Article: How much can environment affect intelligence? In one study, striking increases in IQ occurred in 25 children who were moved from an orphanage to more stimulating(,) environments.The children, who were all considered mentally retarded and unadoptable, were moved to an institution where they received personal attention from adults.Later, these supposedly retarded children were adopted by parents who gave them love, a family ,and a stimulating home environment.The children gained an average of 29 IQ points.For one child, the increase was an amazing 58 points.A second group of initially less "retarded" children, who stayed in the orphanage, lost an average of 26 IQ points. Other encouraging results can be found in early childhood education programs, which provide stimulating intellectual experiences for disadvantaged children.In one study, children from low-income families were given enriched environments from early infancy through preschool.By age 2 their IQ scores were already higher than those in a control group.More important, they were still 5 points higher seven years later.High-quality enrichment programs such as Head Start can prevent children from falling behind in school. A particularly striking environmental effect is the fact that 14 nations have shown average IQ gains of from 5 to 25 points during the last 30 years.These IQ boosts, averaging 15 points, occurred in far too short a time for genetics to explain them.It is more likely that the gains reflect environmental forces, such as improved education, nutrition, and living in a technologically complex society. Question: Which of the following is NOT mentioned as an environmental factor that affects IQ _ . Options: A: Good nutrition. B: Improved technology. C: Better education. D: Food pollution.

I'm taking a test and have to guess the right answer to the question after the article. Article: Beijing ---- A recent Chinese blockbuster "A World Without Thieves" is based on the experiences of a young migrant worker carrying 60,000 yuan on a train packed with thieves.But while the image of a warm-hearted but somewhat naive migrant worker may have made film fans chuckle, it's a sure bet that most of China's migrant workers are yet to step into a cinema to admire it. "Forty yuan a ticket? I can't afford it," said Shen Jie, a migrant worker at a construction site in Dongzhimen, east Beijing. Shen found it hard to remember when he last watched a film, or what it was about."It must be 10 years ago," he said. Though they are the builders of the nation's theaters and cinemas, a limited cultural life is common among China's 120 million migrant workers. Shen arrived from East China's Zhejiang Province in1991.Life was better then; money seemed to come more easily."Now, as more and more workers are rushing to the capital, it's too hard to earn money, and none of us dare think about watching films," he said. For many like Shen, the dream is earning enough to pay for their children's education so they can find jobs in the cities and say goodbye to the hardships of rural life forever.This drives them to work hard and save as much as possible. With a monthly salary of less than 500 yuan, Shen has to send money home to his little son and silver-haired parents. In Shen's small dormitory, which he shares with seven other co-workers, there is a well-thumbed copy of a magazine published in 1998. A recent survey by local media revealed that 80 percent of migrant workers spent their spare time sleeping and chatting because of exhaust and a lack of income.The same survey found that 47 percent of migrant workers have to work for more than 10 hours a day.Around 40 percent do not even possess a book, and nearly 60 percent say they are dissatisfied with their cultural life. Like many of Shen's co-workers, reading newspapers and hanging out in... Question: We can infer from the passage "A World Without Thieves" is a film that _ . Options: A: talks about experiences of a group of thieves B: deals with the life of migrant workers C: explains how to catch thieves on trains D: attracts many migrant workers

I'm taking a test and have to guess the right answer to the question after the article. Article: If you have ever been left wondering why your emails are riddled with grammatical errors, or why you can never quite find the right phrase, it may be because you are typing with both hands. Our vocabulary becomes richer and our writing style becomes more fluent when we type using just one hand, scientists have found. "Typing can be too fluent or too fast, and _ can actually weaken the writing process," said Srdan Medimorec, the lead author of the study conducted at the department of psychology at the University of Waterloo, Canada. "It seems that what we write is a product of the interaction between our thoughts and the tools we use to express them." Using text-analysis software, researchers asked 103 university students to write essays under different conditions, using one hand to type and using both hands to type. The software was used to analyze elements of the essays, such as range of vocabulary, sentence complexity and the cohesion of the writing. Researchers found that participants' vocabulary became more advanced when they typed with one hand rather than two. The research team said that by slowing our writing down, typing one-handed allows more time for an internal word search, resulting in a larger variety of words. In contrast, fast typists might just write the first word that comes to mind. However, it is important not to slow typing down too much. Those who typed essays one-handed in the current study slowed down to about the speed of handwriting. This is the first study to show that changing people's typing can make their writing get better. The researchers suggested that the speed of writing could affect writing quality regardless of the tools used, whether they are computers, or pen and paper, although further research would be required to prove that idea. Question: Which is the best title of the passage? Options: A: How to become a good writer? B: Typing with both hands could make you a worse writer. C: Slower typing, fewer mistakes. D: Elements weakening the writing process
