Ques: Read the article and select the best answer. Article: Several weeks ago, a mysterious Christmas card dropped through our mailbox. The envelope was addressed to a man named Raoul, who, I was ly certain, did not live with us. The envelope wasn't sealed, so I opened it. The inside of the card was blank. Ed, my husband, explained that the card was both from and to the newspaper deliveryman. His name was apparently Raoul, and Raoul wanted a holiday tip. We were meant to put a check inside the card and then drop the envelope in the mail. When your services are finished at 4 a.m., you can't simply hang around, like a hotel bellboy expecting a tip. You have to be direct. So I wrote a nice holiday greeting to this man who, in my imagination, fires The New York Times from his bike aimed at our front door, causing more noise with mere newsprint than most people manage with sophisticated black market fireworks. With a start, I realized that perhaps the reason for the 4 a.m. wake-up noise was not ordinary rudeness but carefully executed spite : I had not tipped Raoul in Christmas past. I honestly hadn't realized I was supposed to. This was the first time he'd used the card tactic . So I got out my checkbook. Somewhere along the line, holiday tipping went from an optional thank-you for a year of services to a Mafia-style protection racket . Several days later, I was bringing our garbage bins back when I noticed an envelope taped to one of the lids. The outside of the envelope said MICKEY. It had to be another tip request, this time from our garbage collector. Unlike Raoul, Mickey hadn't enclosed his own Christmas card from me. In a way, I appreciated the directness. "I know you don't care how merry my Christmas is, and that's fine," the gesture said. "I want $30, or I'll 'forget' to empty your garbage bin some hot summer day." I put a check in the envelope and taped it back to the bin. The next morning, Ed noticed that the envelope was gone, though the trash hadn't yet been picked up: "Someone stole Mickey's tip!" Ed was quite certain. He made me call the bank and cancel... Question: From the passage, we learn that the author _ . Options: A: didn't like Raoul's way of delivering the paper B: didn't realize why Raoul delivered the paper that way before C: didn't know that Raoul delivered the paper for them D: didn't feel it necessary to meet Raoul when he came
Ans: B

Ques: Read the article and select the best answer. Article: Scientists Alan M.Goldberg and Thomas Hartung describe recent advances in replacing the use of animals in toxicology testing.Improvements in cell and tissue culture technologies,for example,allow a growing number of tests to be performed on human cells alone.Computer models are becoming increasingly complex and many could one day become more accurate than trials in living animals. Since the late 1990s,Huntingdon Life Sciences--a company that conducts testing of substances on animals conducted by the Environmental Protection Agency and the Food and Drug Administration--has become a proving ground for aggressive strategies by animal-rights militants .At a hearing,a Senate.committee listened to testimony against Huntingdon employees and financial institutions providing services to the company.One experimentation witness at the hearing insisted that any means necessary were justified to spare animals' lives;he has previously accepted the idea of murder to that end. Use of animals in testing and in biomedical research continues to be necessary in many instances and is ethically preferable to experimenting on humans or giving up cures that could save human lives.But for the sake of people and animals alike,the development and acceptance of animal substitutes deserve enthusiastic support. In some instances, substitutes are already thought as good or better than animals,but supervising agencies have yet to catch up.In both the European Union and the U.S.,scientists and companies wanting to use the new alternative tests complain that regulatory standards for proving a drug or chemical to be safe for humans force the continued use of animals.Thus,animal-loving Americans might turn to persuading the EPA and the FDA to speed validation of new methods so that they can be more widely employed.And animal advocates who want to influence business could consider investing in the small biotech's and large pharmaceutical companies that are working to develop alternatives to animals in research. Question: Accordingly, the animal-rights militants hold the view that _ . Options: A: animals shouldn't be used in toxicology testing B: animals should enjoy equal rights with human beings C: animals should live wildly and freely D: we should protect animals from being killed casually
Ans: A

Ques: Read the article and select the best answer. Article: -American office workers spend an average of 52 hours a week at their desks, according to a statistic survey. Some might argue that not all that time is spent working,but still all those hours in windowless offices with artificial light can have an influence. A few green additions could have a large effect on worker happiness,according to the survey led by Tina Cade from Texas State University. "We pretty much found out that if you had windows and plants or even if you just had plants in your office, you were more satisfied with your job," Cade told LiveScience. "We thought it was important for offices because a lot of times people are looking for ways to keep employees happy and do all these expensive things like building a gym. Maybe for less investment they could put in a few plants in important places." The team surveyed 450 office workers in Texas and the Midwest,asking questions about job satisfaction and the work environments. When asked about their overall life quality,82 said they felt "content" or "very happy". Only 69 percent of those who work with plants but without windows,and 60 percent of those who have windows but no plants, said they felt this way. The group of people who work without plants or windows were the most dissatisfied,with only 58 percent of them saying that overall they were "content" or "very happy". While no one who works with plants,windows,or both reported they felt "miserable", 0.8 percent of those who work in offices without either said they were "miserable". "I was really surprised that having a plant in your office appeared to be more beneficial than having a window in your office," Cade said. "Everybody says, 'I need a window!' but actually it seemed like a plant could be a suitable alternative." Question: What does the passage mainly tell us? Options: A: Green plants can increase job satisfaction. B: An easier way to increase job satisfaction. C: What the best working environment is. D: Who are happy with their job environment.
Ans:
A
