input: OPTIONS:

- is doubted by many people
- has found it is harder to learn numbers than learning a sign language
- has shown that our understanding of numbers is influenced by our mastering of language. Now, answer this question: Read the following article and answer the question. Article: A new study has found some secrets of people's understanding of large numbers. Researchers studied a group of people who were born deaf and never learned any spoken language or a formal sign language, but they have developed a gesture system to communicate with people around them. The gestures let them express approximate amounts, but not exact numbers. "Up to three, they're fine," says Elizabet Spaepen, a researcher at the University of Chicago and an author of the study. "But past three, they start to fall apart." In one test, Spaepen would knock her fist against a study participant's fist a certain number of times and then ask them to respond with the same number of knocks. "If I were to knock four times on their fist, they might knock on my fist five times," she says. The finding offers a clue to just how much language affects our understanding of numbers. That has been a big question since 2004, when other researchers published data on two tribes in the Amazon whose members also lack words for big numbers. "What they have are words that mean one and two," Spaepen says, "and then they have a word to mean many." Members of the Amazonian tribes also had trouble matching numbers larger than three or four. But some scholars felt that these earlier studies failed to prove that language was the reason. They pointed out that the tribes lived in groups that didn't use money and had no need for exact numbers. The new research appears to answer that criticism. "It proves that the kinds of problems in understanding numbers that we found in the Amazonian tribes are not due to just the cultural or environmental circumstances," says Peter Gordon of Columbia University, one of the researchers involved in the earlier studies. Question: According to the passage, the new study _ . Answer:
A:
output: has shown that our understanding of numbers is influenced by our mastering of language.

Read the following article and answer the question. Article: A little old couple walked slowly into McDonald's one cold winter evening. They were so old that they looked out of place amid the young families and young couples eating there that night. Some of the customers looked admiringly at them. You could tell what the admirers were thinking. "Look, there is a couple who has been through a lot together, probably for 60 years or more!" The little old man walked right up to the cash register, placed his order with no hesitation and then paid for their meal. The couple took a table near the back wall and started taking food off the tray. There was one hamburger, one order of French fries and one drink. The little old man unwrapped the plain hamburger and carefully cut it in half. He placed one half in front of his wife. Then he carefully counted out the French fries, divided them in two piles and neatly placed one pile in front of his wife. He took a sip of the drink, his wife took a sip and then set the cup down between them. As the man began to eat his few bites of hamburger the crowd began to get restless. Again you could tell what they were thinking, "That poor old couple. All they can afford is one meal for the two of them." As the man began to eat his French fries one young man stood and came over to the old couple's table. He politely offered to buy another meal for the old couple to eat. The old man replied that they were just fine. They were used to sharing everything. Then the crowd noticed that the little old lady hadn't eaten a bite. She just sat there watching her husband eat and occasionally taking turns sipping the drink. Again the young man came over and begged them to let him buy them something to eat. This time the lady explained that, no, they were used to sharing everything together. As the little old man finished eating and was wiping his face neatly with a napkin the young man could stand it no longer. Again he came over to their table and offered to buy some food. After being politely refused again, he finally asked a question of the little... Question: Why did some of the customers admire them? Answer:

OPTIONS:
- Because they walked in hand in hand
- Because they come to McDonald's together
- Because they have been together for many years
- Because they come in such a cold winter evening

Answer: Because they have been together for many years

Read the following article and answer the question. Article: Never Talk to Strangers? "Never talk to strangers." Many children are taught this simple rule as a precaution against abduction . In June, 2005, an 11-year-old boy was lost in the Utah wilderness for four days. During that time, he stayed on the path. He saw people searching for him but deliberately hid from them, afraid someone might "steal" him. Eventually, the unfortunate game of hide-and-seek ended and he was found. According to the Canada Safety Council, this alarming incident shows how unwise it is to instill a fear of strangers in children. The "stranger danger" message can prevent children from developing the social skills and judgment needed to deal effectively with real-life situations. In a difficult situation, a stranger could be their lifeline to safety. To have a child go missing is a parent's worst nightmare. The threat of abduction by a stranger is minimal when compared with other possible reasons for a disappearance. In 2004, there were 67,266 missing-children cases in Canada. Only 31 involved abduction; in most of those cases the abductor was a relative, friend, or person known to the family. There were 671 cases of children wandering off, and 332 cases of abductions by a parent. Almost 80 percent of all cases were runaways. These statistics cast doubt on the idea that children should never talk to strangers. Wandering off is more common--but a lost children may have to call upon a stranger for help, and must develop the ability to judge what kind of people to approach. The "never talk to strangers" rule does not protect children in the situations they are most likely to face. On top of this, it can be confusing. Adults do not model the behaviour; they often talk to strangers. A child may not know how to tell who is a stranger, and who is not. For young children, nothing replaces close supervision . Pre-schoolers do not understand risk and tend to act without thinking. Children need to develop habits and sttitudes that will protect them from the real threats and dangers they may face. The...
