问题     In an initiative to speed treatments for wounded soldiers, the U.S. Department of Defense(DOD)is entering the fast-growing field of regenerative medicine. Over the next 5 years, at least $250 million will be tunneled into two university-led consortia that compose the new Armed Forces Institute of Regenerative Medicine(AFIRM), DOD announced last week.
    AFIRM will focus on regrowing severed fingers, recreating shattered bones, reconstructing mutilated faces, and covering burn victims with genetically matched skin. "We hope to get products into patients within 5 years," says tissue engineer Anthony Atala of Wake Forest University Baptist Medical Center in Winston-Salem, North Carolina, co-director of one consortium led by Wake Forest and the University of Pittsburgh in Pennsylvania.
    Last year, Atala reported isolating from amniotic fluid highly versatile stem cells, which are likely to figure prominently in the new technologies. Embryonic stem cells or their equivalents aren’t in the mix here. Rather, says Atala, the focus is on getting rapidly to the clinic, using cells that can get quick Food and Drug Administration approval.
    DOD decide 2 years ago that it was time to make a major commitment to regenerative medicine treatments, largely at the instigation of dental researcher Robert Vandre, director of combat casualty care research at the U. S. Army Medical Research and Materiel Command at Fort De-trick, Maryland. Vandre says he originally managed to round up a commitment for $8.5 million a year, including $500,000 a year from the U. S. National Institutes of Health(NIH). Then after receiving competitive proposals for a single consortium, he got a call "out of the blue" from the White House, which ended up telling DOD to double the funding from $42.5 million to $85 million over 5 years. That made it possible to fund two consortia that had come in neck-and-neck in the competition. Vandre, who is AFIRM’s DOD manager, says the 5-year total should top $265 million, including $80 million in public and private funds to match DOD’s input and some $100 million in NIH grants already held by researchers in the consortia’s 28 researchgroups.
    A top priority will be engineered skin that can be quickly grown to treat burn victims. Atala points out that at present there is " no real skin replacement" because skin grafts from cadavers are prone to rejection; supply is also short. One of the earliest fruits of the venture may be a method to grow a patient’s own skin rapidly enough to use as a graft for life-threatening burns. Ultimately, says chemist Joachim Kohn of Rutgers University in New Brunswick, New Jersey, co-head of the other consortium, led by Rutgers and the Cleveland Clinic in Ohio, "you could take a skin sample from every soldier in danger zones and store it" so that the moment a soldier is injured, people back at the Army medical center in San Antonio, Texas, could start growing a graft.
What was the result of doubling the funding from $42.5 million to $85 million over 5 years?
选项 A、There would be much more wounded people who can be cured.
B、Another consortium could come in to compete with the planned one.
C、Researchers in the consortia’s 28 research groups could get more public and private funds to match DOD’s input.
D、Robert Vandre would change the consortium to a larger one.
答案B
解析 事实细节题。根据题干关键词doubling the funding from $42．5 million to $85 million定位至第四段。基金加倍的结果为“可以资助两个集团，让他们在竞争中齐头并进”，这就意味着在原计划的一个集团之上再加一个集团来促进竞争，所以[B]为正确答案。[A]原文没有直接提及，故排除；[C]是some $100 million in NIH的结果，故排除；原文含义只是增加一个竞争者，并非扩大化，故排除[D]。
