I'm taking a test and have to guess the right answer to the question after the article. Article: Joseph Francis Charles Rock (1884-1962) was an Austrian-American explorer, botanist, and anthropologist . For more than 25 years, he travelled extensively through Tibet and Yunnan, Gansu, and Sichuan provinces in China before finally leaving in 1949. In 1924, Harvard sent Joseph Francis Rock on a treasure hunt through China's southwestern provinces--the Wild West of their day. But gold and silver weren't his task: Rock, a distinguished botanist, sought only to fill his bags with all the seeds, saplings, and shrubs he could find. During his three-year expedition, he collected 20,000 specimens for the Arnold Arboretum . Botany, though, was just one of Rock's strengths. As an ethnologist , he took hundreds of photographs of the Naxi, a tribe in Yunnan province, recording their now-lost way of life for both Harvard and National Geographic, and took notes for an eventual 500-page dictionary of their language. His hand-drawn map of his travels through China's "Cho-Ni" territory, in the Harvard Map Collection, includes more than a thousand rivers, towns, and mountains indicated in both English and Chinese, and was so well made that the U.S. government used it to plan aerial missions in World War II. Scientist, linguist, cartographer, photographer, writer--Rock was not a wallflower in any sense. Arrogant and self-possessed, he would walk into a village or warlord's place "as if he owned the place," said Lisa Pearson, the Arboretum's head librarian. In declaring his successful return under the headline "Seeking Strange Flowers, in the Far Reaches of the World," the Boston Evening Transcript ran a large photo of the daring explorer wearing in a woolly coat and fox-skin hat. "In discussing his heroism including hair-raising escapes from death either from mountain slides, snow slides and robber armies, he waves the idea away as if it is of no importance." The Arboretum and Rock parted ways after 1927, mainly because his trip cost Harvard a fortune--about $900,000 in today's dollars. Fortunately, many of his specimens,... Question: What is the passage mainly about? Options: A: Rock's service for the U.S government. B: Rock's cooperation with Harvard. C: Rock's work as a botanist. D: Rock's exploration in Southwest China.

I'm taking a test and have to guess the right answer to the question after the article. Article: What are the specific traits that will assist executives to climb the ladder of success? Opinions vary widely. Given almost equal qualifications and circumstances, some claim the success factor is largely a matter of luck--being in the right place at the right time. Others speak of an almost crazy devotion to work, combined with a degree of ruthlessness. One"expert" believes that it's undoubtedly a matter of how much education your mother had. To make it big, executives must possess four basic skills: First, drive . Business success takes an unusual amount of energy. A successful executive -- almost by definition--is a striver. He will get tense when he is not striving. Second, people sense. Some say being able to judge people is more important than a high IQ. The skill can be instinctual , but in most cases it is painstakingly learned. Third, communications ability. Different executives make themselves understood in different ways, Some transmit ideas best face to face; others are masters of the telephone call; still others are persuasive writers. One way or another, they all communicate clearly. Fourth, calm under pressure. No businessman will get very far if he chokes up. Question: What's the main idea of the passage? Options: A: Four skills for successful executives B: Some opinions about the success. C: Specific characteristics for successful executives. D: Qualifications and circumstances for climbing the ladder.

I'm taking a test and have to guess the right answer to the question after the article. Article: Because I am extremely vulnerable to both slick advertising and peer pressure, I've been thinking about getting an iPad. But here's the problem: I'm cheap, and the iPad's not. If I'm going to fork over at least $499 for a new device, I want to try it out and make sure it's not just a larger, shinier version of my iPhone. But if I went to my local Apple Store, I'd get to spend only a few minutes testing out the machine. I wanted more time than that, so I rented one for $15 a day from a guy on SnapGoods. The Internet start-up in Brooklyn runs on simple reasoning: there are people who want to borrow stuff - camping equipment, food processors, robot vacuums, etc. - and there are people who have stuff they want to lend. SnapGoods helps these two groups connect over the Web. SnapGoods is one of many sites that have sprung up to facilitate offline sharing. Some sites have a narrow, obvious focus (like SwapBabyGoods.com) while others are more obscure (Neighborhood Fruit helps people share what's growing in their yards or find fruit trees on public land). But regardless of whether the sharing is free or involves a fee, these transactions often come with a stick-it-to-the-man attitude. "Borrow these things from your neighbors," reads one earnest request on neighborrow.com, "The owner-ship has SAILED!" All of these sites are encouraging something academics call collaborative consumption - in other words, peer-to-peer sharing or renting. Renting something you don't need to use very often makes a lot more sense than buying it and letting it collect dust in your garage. There's a green aspect as well, since sharing helps cut down on overall use of resources. But one of collaborative consumption's most surprising benefits turns out to be social. In an era when families are scattered around the country and we may not know the people down the street from us, sharing things - even with strangers we've just met online - allows us to make meaningful connections. "This isn't just about saving the environment or saving a dollar,"... Question: SnapGoods is a website which _ . Options: A: facilitates online sharing B: helps people borrow things from their neighbors C: connects borrowers and lenders for stuff sharing D: sells iPad online
