Read the following article and select the best answer. Article: Most kids get bored with their toys quickly, even the newest ones. The service of renting toys can save parents from buying lots of new toys for their kids. The new web-based company, Baby Plays, was invented by Lori Pope, a mother of twin boys. When her kids' toys started taking over all the floor space in her house, she thought that maybe she didn't need to buy so many toys. What's more, her kids seemed to lose interest in each new toy very quickly. Finally she realized that she needed a special service. She wanted to borrow one toy at a time. When her kids didn't like it any more she could send the toy back. But she couldn't find any service like that, so she decided to create her own. Pope owned a company before. She poured a lot of money into Baby Plays to buy all the best toys. These toys are for children aged from 0 to 5. Under her plan, customers can rent six toys each month. The price for renting a new toy is less than most costs of buying a new toy. Generally, families will keep each toy for one month. This period is plenty for most kids to get tired of playing with it. If the kids are really interested in a particular toy, they can keep it till they are attracted to a new one. Kids are not good at keeping their toys in perfect condition, but Pope doesn't mind a little wear and tear. She thinks that even if the kids don't care about their toys' condition, the parents do. And she will not ever rent anyone a low-quality toy. Question: Why did the mother invent a rent-a-toy company? - Because she got bored with her toys quickly. - Because she wanted to make money. - Because she was interested in starting a web business. - Because her kids got bored with toys quickly.
Because her kids got bored with toys quickly.

The finding comes weeks after leading scientists reported children born to men over the age of 45 run a higher risk of having autism and mental disorders. With age, sperm -producing cells do not copy a man's DNA as effectively, leading to genetic mutations. Martin Fielder, an anthropologist at Vienna University, told the Sunday Times: 'Every 16 years the mutation rate doubles. Other researchers found 25 mutations per sperm in a 20-year-old, but at age 40 it is 65 mutations. By 56, it doubles again. The effect is very visible - someone born to a father of 22 is already 5-10 per cent more attractive than those with a 40-year-old father and the difference grows with the age gap. In contrast, women pass on a maximum of 15 mutations to their baby, regardless of age, according to the study published in the journal Nature. Surveying a group of six men and six women, researchers showed them each 4,018 photographs of 18-20-year-old men and 4,416 of women the same age, and asked to assess their attractiveness. Those with older fathers were consistently considered less attractive. However, the children of older men, though less attractive, are likely to outlive their peers with younger fathers, it is claimed. Professor Lee Smith, a geneticist at Edinburgh University, told the Sunday Times other research found such children have longer telomeres - the caps on the end of chromosomes --- which are associated with longer life. But the mounting research connecting parents' age with autism is cause for concern, experts warn. Autism is an umbrella term for a range of developmental disorders that have a lifelong effect on someone's ability to interact socially and communicate openly. In the UK, around one in 100 adults is thought to be affected by autism, mostly men, caused by a combination of genetic and environmental factors. Researchers said men should be advised about the potential problems in order to help their personal... Question: What does the passage say about autism? _ - Genetic mutations inside a person cause autism - Environmental factors contribute to autism - In the UK, one percent of its population are affected by autism - Autism prevents people from interacting socially and communicating openly
Autism prevents people from interacting socially and communicating openly

*Question*
Read the following article and select the best answer. Article: In May, 2014, some Chinese tourists found a Chinese-character message "Ding Jinhao once visited here" on a statue of god in a 3500-year-old Egyptian temple. An angry tourist took the photograph of the scrawl and posted it on social media Sina Weibo. It was quickly spread and there were more than 100,000 comments during two weeks. Later, a 15-year-old Chinese boy was searched out as the person who caved this message. Many netizens expressed their anger and disappointment for the uncivilized behavior. They searched and identified the boy and then posted his personal information including the address and pictures online.
