1. Every year millions of women are screened with X-rays to pick up signs of breast cancer. If this happens early enough, the disease can often be treated successfully. According to a survey published last year, 21 countries have screening programmes. Nine of them, including Australia, Canada, the US and Spain, screen women under 50.
2. But the medical benefits of screening these younger women are controversial, partly because the radiation brings a small risk of inducing cancer. Also, younger women must be given higher doses of X-rays because their breast tissue is denser.
3. Researchers at the Polytechnic University of Valencia analysed the effect of screening more than 160,000 women at 11 local clinics. After estimating the women’s cumulative dose of radiation, they used two models to calculate the number of extra cancers this would cause.
4. The mathematical model recommended by Britain’s National Ra

[单选题]根据下面资料，回答 Everyone agrees that innovation is the key to solving the many challenges we face as a country from health care to education to the environment, and is fundamental to restoring economic growth and prosperity. But I would put it a slightly different way. We must find a way to rebuild the "innovation infrastructure" in this country. The problem is not that Americans aren′t as inherently innovative as ever we are. And the level of interest among Americans in the process of innovation--determining the best recipes to make it happen--has been skyrocketing over the past few years. For example, the number of times the word "innovation" appeared in Google news stores has increased by approximately five from Obama′s inauguration to today. Google the term "innovation" and you′ 11 get 342 million hits, approximately half the 676 million hits that "Obama" generates. And according to hash tags org, innovation is trending about the same rate as deficit. Our problem is that the system is failing our citizens. The "seed corn" of innovation-creative ideas ... fundamental rate it was before. Viable "seed corn" requires an innovation infrastructure in which bright minds are provided the resources and freedom to create and invent according to their passions and curiosities, to take bold risks, and even to fail. Such an innovation infrastructure thrived in the U.S. in the late 20th century as a collaboration that put Americans on the moon, and to the personal computer, the Internet, and the era of genomic medicine. Americans are ready and willing to embrace the goal of once again leading the world in innovation. This could be the moon shot for the next decade that unifies our country. However, we are at a tremendous disadvantage unless the innovation infrastructure of this country is rebuilt. This requires a new collaboration among government, industry and academia-one that is suited to the challenges and opportunities of the digital age, and that restores the bold risk taking and action orientation of earlier times. The main content of the text can be summarized as____________.
A.the main problem about innovation and the solution
B.the optimistic aspects of the development of innovation
C.the analysis of the advantages and disadvantages of innovation
D.the pessimistic prediction of the development of innovation
