问题     Yesterday at the UN several groups, including Rotary International, the World Health Organization, and the Bill & Melinda Gates Foundation met to discuss their commitment to, and the strides made, campaigning to end polio worldwide.
    Yesterday Rotary announced, the side event—"Our Commitment to the Next Generation: The Legacy of a Polio-free World"—brought together leaders of the remaining endemic countries, and representatives of donor governments, development agencies, the GPEI partners, and the media to underscore the urgent need to finish the job of global polio eradication. Although the wild poliovirus is endemic only in Afghanistan, Pakistan, and Nigeria, other countries are still at risk for re-established transmission of the virus through its " importation" from the endemics.
    Millions have been pledged towards the effort and we are slowly watching countries become polio-free. Unfortunately, polio and other preventable diseases could(and already are)facing a renaissance thanks to dangerous parenting fads in the West.
    For several years, rumors have spread through all-natural, hippie parenting circles that vaccines contain chemicals that cause autism(a mental disorder that affects children, particularly their ability to relate to other people). They maintain, despite a total lack of scientific evidence, that children have been disabled and incapacitated by mercury and other preservatives in vaccines. The one scientific study that might have made their case was discredited last year and its results thrown out. Despite this, many famous parents, including Jenny McCarthy(of MTV fame)and Mayim Bialik(TV’s Blossom)have publicly condemned vaccine research while declaring their children to be unvaccinated. Unfortunately, these conspiracy theories have hit the political mainstream as well. During the primaries this year Rep. Michele Bachmann repeated rumors she heard from an audience member at a debate about vaccine safety. In 2008, both candidates for President spread vaccine misinformation, claiming that the science was still undecided on the link between vaccines and autism.
    The millions of dollars raised and spent by governments and organizations to end polio worldwide is money well-spent. Unfortunately, one epidemic could undo the decades of work making this vaccine available to every child in the world. We’ve already seen outbreaks of deadly and entirely preventable diseases like whooping cough and the measles, and instances of diseases with vaccines available have increased as immunization opt-outs rise. While it’s admirable that these groups are working to make vaccines available in the most remote villages in the world, parents in Portland and other liberal epicenters are setting medical science back fifty years in the United States.
    All children, regardless of their parent’s scientific ignorance, need and deserve access to vaccines that were developed not just for their own sake, but also for the sake of public health. After these groups manage to get vaccines to children in isolated villages in Pakistan, perhaps they should schedule a stop-over in on their way home to explain science to self-described "educated" parents. Public health groups should be emphasizing the importance of vaccines in Pakistan and in Park Slope lest their efforts become undermined by parents in the latter.
It can be learned from the 4th paragraph that

选项 A、mercury and other preservatives in vaccines do harm to children.
B、autism has something to do with vaccine.
C、some people are misled about polio vaccine.
D、people from politics are positive about polio vaccine.

答案C

解析 事实细节题。根据题干提示定位至第四段。从该段第一句可以看出一些嬉皮圈子的家长担心疫苗里的化学成分而怀疑和担心疫苗的安全性,而且一些名人甚至政界人士都听信了这种传言,说明很多人被误导,因此选[C]。该段二、三句提到没有科学证据表明脊灰疫苗和儿童的丧失能力或孤独症有联系,故排除[B]。
