Researchers have identified 1.4 million animal species so far—and millions remain to be discovered, named, and scientifically described. So how much would it actually cost to【C1】______ every animal on Earth? A pair of Brazilian scientists has crunched (大量运算) the numbers and【C2】______ up with an answer: $263 billion.
That’s way more than the $ 5 billion that famed Harvard University biologist Edward O. Wilson estimated back in 2000—and that was for every species on Earth, not just animals. But even $263 billion would be a【C3】______price to pay to understand the creatures that【C4】______such essentials as agriculture, fisheries, new drugs, and energy sources, says ornithologist (鸟类学家) Joel Cracraft of the American Museum of Natural History in New York City. "Literally, the world economy runs on biodiversity," he says. "People don’t understand really, deeply how much we depend on biodiversity."
Most biologists agree that with extinction rates【C5】______and climate change looming, the【C6】______to document the planet’s biodiversity—or biota (生物区)—is urgent,【C7】______considering the essential role these life forms play in crop pollination, clean air, and other aspects of human【C8】______ "We are losing species by extinction faster than we are describing new species" according to some estimates, says biologist Antonio Marques, who【C9】______ the new paper with Fernando Carbayo, both at the University of St. Paulo in Brazil. "We have to know the biota to preserve and conserve the biota," he says.
Besides the money, another huge【C10】______ to a complete understanding of the animal kingdom is a global shortage of taxonomists (分类学家), experts say.

选项
答案
E
解析
固定搭配题。空格所在句的主语为A pair of Brazilian scientists,根据and前面的并列结构has crunched可知,此处也应填入动词的过去分词形式。空格后为up with,所给动词中,come与up with能构成固定搭配,表示“想出,得出”,故选come。
