[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.
Today′ s structures of innovation need to be rebuilt because ____________.
A.Americans have lost interest in innovation during the past years
B.too many risky ideas have destroyed people' s confidence in innovation
C.institutions, government and business cannot cooperate effectively as before
D.the essential elements of innovation have lost its energy for development
