Read the following article and select the best answer. 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 caused Rock to stop work for The Arboretum? - The vast expense. - The dangerous journey. - The challenging tasks. - The unknown world.
The vast expense.

Read the following article and select the best answer. Article: In the animal kingdom, weakness can bring about aggression in other animal. This sometimes happens with humans also. But I have found that my weakness brings out the kindness in people. I see it every day when people hold doors for me, pour cream into my coffee, or help me to put on my coat. And I have discovered that it makes them happy. From my wheelchair experience, I see the best in people, bur sometimes I feel sad because those who appear independent miss the kindness I see daily. They don't get to see this soft side of others often. We try every way possible to avoid showing our weakness, which includes a lot of pretending. But only when we stop pretending we're brave or strong do we allow people to show the kindness that's in them. Last month, when I was driving home on a busy highway, I began to feel unwell and drove more slowly than usual. People behind me began to get impatient and angry, with some speeding up alongside me, horning or even shouting at me. At the moment I decided to do something I had never done in twenty four years of driving. I put on the car flashlights and drove on at a really low speed. No more angry shouts and no more horns! When I put on my flashlights, I was saying to other drivers, "I have a problem here. I am weak and doing the best I can." And everyone understood. Several times, I saw drivers who wanted to pass. They couldn't get around me because of the stream of passing traffic. But instead of getting impatient and angry, they waited, knowing the driver in front of them was in some way weak. Sometimes situations call for us to act strong and brave even when we don't feel that way. But those are few and far between. More often, it would be better if we don't pretend we feel strong when we feel weak or pretend that we are brave when we are scared. Question: What did the other drivers do when they saw the flashlights? - They speed up to pass. - They waited with patience. - They tried their best to help. - They put on their flashlights too.
(Answer)
They waited with patience.
