Q: Read the following article and answer the question. Article: On a cool summer night in Wyoming, Dean Biggins waits patiently in his truck. Suddenly, Biggins, a wildlife biologist, spots a pair of eyes in the distance. Baggins can't believe his luck: He's just caught sight of a black-footed ferret  --one of the world's rarest animals. Just over a century ago, hundreds of thousands of black-footed ferrets lived on the grasslands in North America known as the prairie. But the animals died off as prairie dog disappeared. Black-footed ferret depend on prairie dogs for both food and shelter. After a ferret has eaten a prairie dog, it moves into the animal's burrow . When cattlemen started setting up ranches  on the prairie in the early 1900s, they thought prairie dogs, which eat grass, might compete with their cattle and sheep for food. To make sure that didn't happen, they killed off billions of prairie dogs. As prairie dog populations dropped, black-footed ferrets disappeared. By 1979, researchers couldn't find any ferrets and declared the species extinct. Then, two years later, a small group was discovered. Although scientists were excited about the discovery, it soon became clear that the ferrets were in danger. A disease called sylvatic plague  was killing the ferrets. Soon, just 18 ferrets remained. "To help the species survive, the researchers put all the ferrets in cages in 1986 and began raising them," says Randy Matchett, a wildlife biologist. To help the black-footed ferrets learn survival skills, wildlife biologists put them through a process called preconditioning. Researchers build a fence around old prairie dog burrows and put the ferrets in them when they are a couple of months old. While the animals get used to their new home, researchers feed them live prairie dogs so they can practice hunting. "Now about 1,000 black-footed ferrets are back in the wild. Despite their amazing comeback, black-footed ferrets aren't out of the woods yet," says Matchett. Sylvatic plague is still a threat, and ranchers still don't want too many prairie dogs on their land. "We... Question: What's Matchett's attitude towards the future of black-footed ferrets? Answer:
A: Hopeful.

Q: Read the following article and answer the question. Article: When I had breast cancer I had to have chemotherapy  . The hardest part of that entire experience was losing my hair. It was like having a tattoo  across my forehead that said "chemotherapy patient." I am a very active and athletic person, so to have people looking at me with pity as if I was an invalid was very hard to take. Of course they never said anything, but if I got in an elevator. Everyone looked away because they didn't know what to say. But I didn't blame them. The best compliment I ever received was when I was at work one day, wearing my scarf over my bald head, and a UPS guy came in to deliver a package. He looked me right in the eye and said, "So, are you on chemotherapy?" I said, "Yes, thank you for asking. You are the first person to actually acknowledge that fact." It felt so good to be talked to like a "real" person, without any pity, just the facts. I asked him what made him decide to say something, and he told me that a woman he worked with had just gone through the same thing several months before. I had some joke business cards that said my job title was "Supreme Commander of the Universe", so whenever this same UPS guy came to deliver a package, he would also say, "Hey, Supreme Commander, how is it going?" Then my company moved to a new location, and since that time I hadn't seen the UPS guy-Bryan- in probably two years. I went to answer my door at home one day, and there was Bryan with a package. Small world. "Hey, Supreme Commander, long time no see!" he said. He sees so many people all day long, every day, delivering packages but he remembered me after two years. What a great compliment! Of course, I remembered him, too, because he was the only person who could see me during that time when I was "the invisible woman." Question: Why did the author say "It felt so good to be talked to like "real" person"? Answer:
A: Because her friends treated her as a patient.

Q: Read the following article and answer the question. Article: Alibaba started taking the lead in China, simply enough, by connecting big Chinese manufacturers with big buyers across the world. Its business-to-business site, Alibaba.com allowed business to buy almost everything. Alibaba's advantage wasn't hard to identify: size. Alibaba is just big, even by Chinese standards. Its marketplaces attract 231 million active buyers, 8 million sellers, 11.3 billion orders a year--and _ It encourages people to use its markets--not charging small sellers a percentage of the sale. If you want a quick look into the influence of Alibaba on daily Chinese life, take my experience. I moved to Beijing almost a year ago and quickly got tired of visiting small stores across the crowded, polluted city of 20 million people in search of new electronics, bathroom furnishings, and anything else my wife wanted. "You're looking for what exactly? Why not try _ ? " my Chinese teacher asked me one day. With that, my wonderful new relationship with Alibaba began. Alibaba's original business-to-business model now is secondary to consumer buying. Chinese retail buying makes up 80% of Alibaba's profit, and leading that group is Taobao, with 800 million items for sale and the most unbelievable selection of things you'll ever find. TMall.com is Alibaba's other big site, where you can find brand name goods from Nike and Unilever near the lowest prices. What I have a hard time explaining to friends and family back in the U.S. is how China has gone beyond traditional shopping--big-box retailers especially --in favor of online purchases on Taobao and a few other sites. In smaller towns than Beijing, where big retailers have not yet traveled, shopping online is shopping, and shopping is Taobao. I have a list of some of my recent purchases on Taobao for a sense of how extensive the marketplace is. Almost everything arrived a day or two after ordering with free shipping. I'm not even a big buyer, because I need friends to help me search the Chinese-language site. When I was searching my purchase history on my... Question: Alibaba's advantage mainly lies in   _  .
