问题     Bill Stone is not an astronaut—he is the world’s most famous caver. Leading large international teams and backed by sponsors like the National Geographic Society, he has mounted more than 50 major expeditions to measure the depth of the most hostile reaches of inner space. Spending weeks underground, his crews have traveled deep inside our planet to the remotest locations touched by humans. Nobody is better at what he does, but this gives him limited satisfaction. He is consumed by ideas for how humanity could explore space and wants to personally establish a privately funded base on Jupiter(木星). It is, he thinks, nothing less than destiny.
    A reasonable observer might choose other words: obsession, fantasy. Bill possesses neither great wealth nor extensive political connections. He is an engineer and runs Stone Aerospace, a company so small that when FedEx rings, he usually signs for the package himself. So to hear Bill talk—"It’s not a big leap for me to go to Jupiter. For Bill, caves are a proving ground. The experience gained there will help people explore outer space.
    But now, after spending nearly three decades on the margins of the space industry, Bill is closer than he’s ever been to proving that caves are the best earthly training ground for exploring space. Backed by a $5-million fund from NASA, he is developing a robot called DepthX that may turn out to be the most advanced autonomous underwater vehicle (AUV) ever. NASA hopes to someday use a robot like Bill Stone’s DepthX to explore Europa, a frozen moon of Jupiter and one of the most probably places in our solar system to support life. Like its inventor, DepthX is a caver, most capable of searching harsh environments. Its theoretical mission, though, is bold even by Bill’s standards: a hunt for extraterrestrial(地球外的) life on Europa.
    Innovator Bill Stone plans to drop one of the world’s most advanced underwater robots, DepthX, into the deepest hole on Earth. If all goes well, this thing just might help get him to Europa DepthX’s first major field trial will take place this month in Mexico’s Zacatén Cenote, the world’s deepest hole. For Bill’s future space ambitions to have any chance, he needs to impress the new generation of wealthy space-loving investors. To do that, he needs to ace(取得好成绩) this first trial and, at 54 years old, he needs to do it fast. As one of his oldest friends puts it, "Time is running out for Bill."
选项 A、They have explored many caves and reached the deepest cave in our planet.
B、They have sponsored the National Geographic Society to explore caves.
C、They have explored the outer space and set up funds for it.
D、They }rave explored and measured the deepest gave in Jupiter.
答案 A
解析 根据题干中的Bill Stone and his teams，可以定位到第一段第二、三句。根据本段的第二、三句可知比尔在国家地理联合会的资助下带领着他的团队进行了50多次探险。他们会在地下工作好几周，测量内部的深度，到人类所能到达的我们这个星球最深的地方去。题目问比尔和他的团队已经完成了什么，应该是他们对我们星球上的许多洞穴及最深的洞穴进行了探测。他们并没有资助国家地理联合会去探测洞穴，而是他们的探测得到了国家地理联合会的资助，故可排除B；他们还没有去探测外太空并建立基金，但这至少是比尔的愿望，故可排除C；他们探测和测量的是地球上的最深的洞穴而不是木星上的，故排除D。
