Article: Steve and Yaser first met in their chemistry class at an American university. Yaser was an international student from Jordan. He wanted to learn more about American culture and hoped that he and Steve would become good friends. At first, Steve seemed very friendly. He always greeted Yaser warmly before class. Sometimes he offered to study with Yaser. He even invited Yaser to have lunch with him. But after the term was over, Steve seemed distant. The two former classmates didn't see each other very often at school. One day Yaser decided to call Steve. Steve didn't seem very interested in talking to him. Yaser was hurt by Steve's change of attitude. "Steve said we were friends," Yaser complained, "and I thought friends were friends forever." Yaser was a little confused. As a foreigner, he doesn't understand the way Americans view friendship. Americans use the word "friend" in a very general way. They may call both casual acquaintances(;) and close companions "friends". These friendships are based on common interests. When the shared activity ends, the friendship may fade . Now as Steve and Yaser are no longer classmates, their "friendship" has changed. In some cultures friendship means a strong lifelong bond between two people. In these cultures friendships develop slowly, since they are built to last. American society is one of rapid change. Studies show that one out five American families moves every year. American friendships develop quickly, and _ may change just quickly as well. People from the United States may at first seem friendly. Americans often chat easily with strangers. But American friendliness is not always an offer of true friendship. After an experience like Yaser's , people who've been in this country for only a few months may consider Americans to be fickle . Learning how Americans view friendship can help non-Americans avoid misunderstandings. It can also help them make friends in the American way. Question: We can learn from the passage that _ . Yes or no, is the answer "Americans always base their friendships with others on common interests"?
Yes

Article: The octopus's reputation as a human-killer isn't simply an exaggeration --it is a total myth. The octopus can indeed be a deadly hunter, but only of its natural victims. Some shellfish and an occasional sick or incautious fish have reason to be frightened of this multi-armed hunter, but a person is much too large to interest even the biggest octopus. Even the largest among octopi is much smaller than most people imagine. Far from being large enough to swallow a ship, as monster octopi in movies have been known to do, the largest octopus, found on the Pacific coast, weighs around 110 pounds and grows to no more than ten feet in width. The hard, parrot-like beak of an octopus is not used for attacking deep-sea divers, but for cutting open shellfish. Indeed, the octopus possesses such a tiny throat that it cannot swallow large pieces of meat. Instead, it feeds by pouring digestive juices into its victims, and then sucking up the soupy remains. A shellfish that finds itself in the grasp of an octopus has only a short time to live. But human beings are perfectly safe. Still, people rarely care to go close enough to these _ to get a good look at them. Question: This passage is mainly about _ . Yes or no, is the answer "octopi and their behavior"?
No

Q: Article: Apparently your mom had it right when she threatened to wash your mouth out with soap if you talked dirty. Lying really does create a desire to clean the "dirty" body part, according to a study by University of Michigan. "The references to 'dirty hands' or 'dirty mouths' in everyday language suggest that people think about abstract issues of moral purity in terms of more experiences with physical purity," said Spike W.S. Lee, a U-M doctoral candidate, who conducted the study with Norbert Schwarz, a psychologist at the U-M Institute for Social Research (ISR), the Ross School of Business, and the U-M psychology department. For the study, Lee and Schwarz asked 87 students to play the role of lawyers competing with a colleague, "Chris", for a promotion. Each was asked to imagine they found an important document that Chris had lost, and that returning the document would help his career and hurt their own career. Each participant was instructed to leave Chris a message by either voice mail or email, telling him who they were and either lying that they could not find his document or telling the truth that they had found the document. Next, participants rated the desirability of several products as part of a supposed marketing survey and reported how much they were willing to pay for each product. The products included mouthwash and hand sanitizer . Study participants who lied on the phone, leaving an untrue and mean voicemail, felt a stronger desire for mouthwash and were willing to pay more for it than those who lied on e-mail. And conversely, those who lied on e-mail, typing the same mean message, felt a stronger desire for hand sanitizer and were willing to pay more for _ . Saying nice and morally correct things, on the other hand, made it less appealing to clean the body part involved in conveying the message. In scientific terms, the findings showed that the embodiment of moral purity is specific to the modality involved in the moral misbehavior. Verbal lying increased participants' assessment of mouthwash... Question: Where can we most likely read this text? Yes or no, is the answer "In a popular science magazine."?
A: No

Article: Bright blue Citi Bikes are becoming a fine sight in the New Yorker street. New Yorkers are gradually getting used to more pedaling passengers on those blue Citi Bikes. But what about local bike shops ? Is City Bike booming at their expense? At Gotham Bikes in Tribeca, a manager who gave his name as "Ben W." said the shop has seen an increase in its overall sales due to the bike-share program. "It's getting more people on the road, more people learning about the sport and getting involved," he said. An employee at Danny's Cycles in Gramercy said Citi Bike is a good option for people in a city famed for its traffic jams and aggressive drivers. "They can try out a bike without buying one:' James Ryan said. Rentals are not a big part of the business at either Gotham Bikes or Danny's Cycles. But for Frank's Bike Shop, a small business on Grand St., the bike-share program has been bad news. Owner Frank Arroyo said that his rental business has decreased by 90% since Citi Bike was launched last month. Arroyo's main rental customers are European tourists, who have since been drawn away by Citi Bikes. However, Ben said the bike-share is good for bike sales at his shop. "People have used the bike-share and realized how great it is to bike in the city, then decide that they want something nicer for themselves," he noted. Christian Farrell of Waterfront Bicycle Shop, on West St. said at first he was concerned about bike-share, though, he admitted, "I was happy to see people on bikes." Farrell's early concerns were repeated by Andrew Crooks, owner of NYC Velo, at 64 Second Ave. "It seemed like a great idea, but one that would be difficult to put into use:' Crooks said of Citi Bike. He said he worried about inexperienced riders' lack of awareness of biking rules and strong negative reaction from non-cyclists. However, he said, it's still too early to tell if his business has been impacted . While it's possible bike-share will cause a drop in business, Crooks agreed that the idea is a positive step forward for New York City. Question: What is the author's chief concern about the increasing use of Citi Bikes in New York? Yes or no, is the answer "Whether local bike shops will suffer."?
