Ques:Read the following article and select the best answer. Article: Do you want to see the effects of global warming? Then head north. Will Steger is going to take all of us there. Steger, 64, the first person to make a dogsled trip to the North Pole, is a very famous and admired polar explorer. He's at home in frozen parts of the world where few humans ever step on. Steger is also a devoted environmentalist who was early to ring the alarm bell on global warming. He saw its effects firsthand in frequent polar expeditions to the Arctic and Antarctica. Now Steger is about to lead a team of six young adventurers on a 1,400-mile, 60-day-long dogsled trip across Ellesmere Island, in the Canadian Arctic. The sea ice in that region should still be frozen. "We want to take our audience to the front lines of global warming," says Steger. The team will be uploading videos, stories and photos to the website globalwarming101.com as they march along, allowing armchair adventurers and kids in classrooms to follow their progress day to day. "We can actually bring the audience up there," Steger says. Steger's team will include some already-famous young explorers. Sam Branson, the 22-year-old son of British airline tycoon Richard Branson, is an experienced Arctic traveler. Also on the journey will be 27-year-old Norwegian Sigrid Ekran. Last year, Ekran became only the second woman in history to win Rookie of the Year for the Iditarod Sled Dog Race. What they will see may be very surprising. Even Steger doesn't know exactly what to expect. Climate change has already reshaped the geography of the Arctic. "Within a decade or less, it's going to be impossible to reach the North Pole by dog team without flotation ," says Steger. Climate change is happening, but people can change too. Their willingness to change will determine the shape of the Earth's future. Question: What would be the best title for the passage? - The Arctic is in danger - Sledding through the Arctic - Discoveries of the Arctic - Consequences of global warming

Ans:Sledding through the Arctic

Ques:Read the following article and select the best answer. Article: Beautiful people are indeed happier,a new study says,but not always for the same reasons. For handsome men,the extra kicks are more likely to come from economic benefits,like increased wages, while women are more likely to find joy just looking in the mirror. "Women feel that beauty is naturally important," says Daniel Hamermesh,a University of Texas at Austin labor economist and the study's lead author. "They just feel bad if they're ugly." Hamermesh is the acknowledged father of pulchronomics, or the economic study of beauty. It can be a dangerous job. He once made angry an audience of young Mormon women, many of whom wished to stay home with future children, by explaining that homemakers tend to be less attractive than their working-girl peers . "Since beautiful women tend to be paid more,they have more motivation to stay in the work force," he says. The pursuit of good looks drives several huge industries--in 2010, Americans spent $845 million on face-lifts alone--but few economists focused on beauty's financial power until the mid-1990s,when Hamermesh and his colleague, Jeff Biddle of Michigan State University, became the first scholars to track the effect of appearance on earnings potential for a large sample of adults. Like many other desirable commodities , "beauty is rare," Hamermesh says, "and that rareness commands a price." A handsome man is estimated to make 13 percent more during his career than a "looks-challenged" peer, according to calculations in Hamermesh's recent book, Beauty Pays. Interestingly, the net benefit is slightly less for pretty women, who may make up the difference by trading on their looks to marry men with higher earning potential. And some studies have shown that attractive people are more likely to be hired in a recession . Hamermesh argues that "there's not much we can do to improve our pulchritude ". There are even studies suggesting that for every dollar spent on cosmetic products,only 4 cents returns as salary--making lipstick a truly awful investment. _ . One...

Ques:Read the following article and select the best answer. Article: Since I started working part-time at a grocery store, I have learned that a customer is more than someone who buys things. To me, a customer is a person whose memory fails entirely once he or she starts to push a shopping cart. One of the first things customers forget is how to count. There is no other way to explain how so many people get in their express line, which is clearly marked 15 items or less, with 20, 25 or even a cart load of items. Customers also forget why they came to the store in the first place. Just as I finish ringing up an order, a customer will say, "Oops, I forgot to pick up a fresh loaf of bread. I hope you don't mind waiting, while I go to get it."Five minutes later, he's back with the bread, a bottle of milk, and three rolls of paper towels. What is strange is that customers also seem to forget that they have to pay for their groceries. Instead of writing a check or looking for a credit card while I am ringing up the groceries, a customer will wait until I announce the total. Then, in surprise, she says, " Oh no, what did I do with my check book?" After 5 minutes of digging through her purse, she borrows my pen because she has forgotten hers. But I have to tolerate customers because they pay my salary, and that's something I can't afford to forget. Question: When customers arrive at the check-out counter, they _ - find their pens lost - go back and get more items - cannot wait to pay for their groceries. - prefer paying by check to paying with a credit card.

Ans:
go back and get more items
