Question: Article: Can you smell two things at once? This experiment comes from the research of two scientists from Rice University. Denise Chen and Wen Zhou have been experimenting with the science of smell, and have made some very interesting discoveries. To explore that, you will need two things with strong, characteristic smells and, of course, your nose. The idea is to smell a different smell with each nostril . Hold one smell very close to your right nostril, and the other smell very close to your left nostril. Then breathe in and pay close attention to what you smell. What you should find is that one smell will be very strong. After another sniff or two, the first smell will go away, and you will smell the other smell. Keep sniffing, and the first smell will come back. Instead of smelling the two smells evenly mixed, they will work in turns, one after the other. Why? Chen and Zhou found that your sense of smell acts much like your sense of sight. Hold a book in front of your nose, so that your left eye sees things on the left side of the book, and your right eye sees things on the right side of the book. You will find that your sight works in turns, first on the left side of the book and then on the right side. Notice that you can't focus your left eye on one object while focusing your right eye on another object. Your brain jumps back and forth , paying attention to one and then the other. The same thing happens with your nostrils. If they are smelling different smells, your brain pays attention to one and then the other.
Question: Denise Chen and Wen Zhou discovered that _ .
Options: (A) our brain focuses on one thing at a time (B) our two nostrils act differently towards the same smell (C) our nose prefers to smell stronger smells (D) our sense of smell is connected with our sense of sight
Asnwer: C

Answer: No

Question: Article: Australia is the largest island in the world. It is a little smaller than China. It is in the south of the earth. Australia is big, but its population is small. The population of it is nearly as large as that of Shanghai. We cannot believe it is such a big country with so small population! Enough laws have been made to fight against pollution. The cities in Australia have little air or water pollution. The sky is blue and the water is clean. You can clearly see fish swimming in the rivers. Plants grow very well. Last month we visited Perth, the biggest city in Western Australia, and went to a wild flowers. Exhibition In spring every year Perth has the wild flower exhibition. After visting Perth, we spent a day in the countryside. We sat down and had a rest near a path at the foot of the hill. But what we saw made us pick up all our things and run back to the car as quickly as we could--there were about three hundred sheep coming towards us down the path! Australia is famous for its sheep and kangaroos. After a short drive from any town, you will find yourself in the middle of white sheep. Sheep ,sheep, everwhere are sheep.

Options: (A) the largest country in the world (B) larger than China (C) as large as Shanghai (D) not so large as China

Question: Article: This summer, Monika Lutz's life took an unusual turn. Instead of heading off to college, the high school graduate packed her bags for a Bengali jungle. Lutz, like a growing number of other young Americans, is taking a year off. Gap years are quite common in Britain and Australia, but they are just beginning to catch on in the U.S. Lutz, who grew up in Boulder, Colo., has put together a 14-month schedule that includes helping deliver solar power to some communities in India and interning for a fashion designer in Shanghai---experiences that are worlds away from the lecture halls and university dormitories that await other students. "I could not be happier," she says. Why are students attracted to the gap-year concept? According to new survey data from Karl Haigler and Rae Nelson, education-policy experts and co-authors of The Gap-Year Advantage, the most common reason for this is to avoid burnout. "I felt like I was focused on college as a means to an end," says Kelsi Morgan, an incoming Middlebury College freshman who spent last year interning for a judge in Tulsa, Okla., and teaching English at an orphanage in the Dominican Republic. The hope is that after a year out of the classroom, students will enter college more energized, focused and mature. That can be an advantage for colleges too. Robert Clagett, dean of admissions at Middlebury, did some research a few years ago and found that a single gap semester was the strongest predictor of academic success at his school. Most experts recommend securing a spot in college before taking a gap year and warn against using the time off to lengthen your resume. "Most admissions folks can see right through that," says Jim Jump, the academic dean of St. Christopher's School in Richmond, Va. But for students like Lutz, who, after getting rejected from five Ivies, decided to take time off, a gap year can help focus interests. Lutz now plans to apply mostly to non-Ivies that have strong marketing programs. "This experience has really opened my eyes to the opportunities the world has to offer," she says. But at least one education expert doesn't want schools spreading the gap-year message. In a study that followed 11,000 members of the high school class of 1992 for eight years after graduation, Stefanie DeLuca, a sociology professor at Johns Hopkins University, found that, all things being equal, those who delayed college by a year were 64% less likely to complete a bachelor's degree than those who didn't. DeLuca did not say whether these students voluntarily started college late, but at the very least, her work indicates that taking a gap year doesn't guarantee success. "I'm not going to say that time off does not have benefits," says DeLuca. "But I think we should not be so enthusiastic."
