问题     Humanity’s greatest accomplishment of the past five decades, declared Bill Gates this week, is the reduction in the number of deaths among young children by half, to 10 million a year in 2007.The world’s most successful capitalist heaped praise on the World Health Organization (WHO), while unveiling an ambitious new global scheme to eliminate polio within a few years. For hispart, the agency’s top polio man, Bruce Aylward, described the fight against the disease in the language of markets: "Elimination is the venture capital of public health: the risks are huge but so too are the rewards."
    The use of this sort of language captures a change in public health in the past decade. The Gates Foundation, with its pots of money and businesslike approach, has transformed the bureaucratic and disheartened world of public health. It has helped revive ailing campaigns, including the fight against polio. This will now get a fresh $600m-plus, from British and German taxpayers, from the Rotary Club International, as well as from the Gates Foundation ($255m).
    The decline from 350,000 new cases in 1988 (when the goal of rapid polio eradication was first declared) to 2,000 cases now (chiefly in Nigeria, India, Pakistan and Afghanistan) looks like a near victory. But the final stretch is the hardest. Only one in 200 cases is readily vulnerable to early detection (as opposed to most victims of smallpox—a serious infectious disease that causes spots which leave deep marks on the skin, already eliminated). Polio is also far more infectious.
    Other obstacles are that the usual vaccine has not worked well in densely populated, disease-ridden central India. Researchers are now trying to find a vaccine that fits those conditions better. Neal Halsey, of Johns Hopkins University, says the "live" vaccines used commonly today must be backed up with further doses of "inactivated" vaccines. These need to become cheaper.
    The fighting in Afghanistan and Pakistan has hampered vaccination programs there. So have rumors among Muslims in northern Nigeria that the vaccination program was in fact a conspiracy to sterilize children That allowed the polio virus to strengthen and spread. The Nigerian strain may have now reached a dozen other countries.
    The final push towards elimination will certainly be costly, though several recent studies suggest that it is cheaper to spend money on a big elimination effort now than to pay the price later for sustained vigilance and health costs. The prospect of a global revival is concentrating minds. That is why, despite the daunting challenges and potential donor fatigue, the world may end up making a go of elimination this time.
By saying "the world may end up making a go of elimination this time"(Lines 4-5, Paragraph 6), the author implies that the world may
选项 A、manage to eradicate polio.
B、fail to achieve the eradication of polio.
C、give up the goal of eradication of polio.
D、begin to eliminate polio.
答案A
解析 语义理解题。根据题干在第六段找到该句，可以发现该句原意为“全世界仍可能最终成功根除小儿麻痹症”。A项中manage to与原句make a go of意义相同。即“成功地做某事”。B项fail to、C项give up与原意相反，排除：D项begin也与原意不符。
