The promise of finding long-term technological solutions to the problem of world food shortages seems difficult to fulfill Many innovations that were once heavily supported and publicized have since fallen by the wayside. The proposals themselves were technically feasible, but they proved to be economically unenviable and to yield food products culturally unacceptable to their consumers.
One characteristic common to unsuccessful food innovations has been that, even with extensive government support, they often have not been technologically adapted or culturally acceptable to the people for whom they had been developed. A successful new technology, therefore, must fit the entire sociocultural system in which it is to find a place Security of crop yield, practicality of storage, and costs are much more significant than what had previously been realized by the advocates of new technologies.
The adoption of new food technologies depends on more than these technical and cultural considerations; economic factors and governmental policies also strongly influence the ultimate success of any innovation. Economists in the Anglo-American tradition have taken the lead in investigating the economics of technological innovation. Although they exaggerate in claiming that profitability is the key factor guiding technical change -- they completely disregard the substantial effects of culture—they are correct in stressing the importance of profits. Most technological innovations in agriculture can be fully used only by large landowners and are only adopted if these profit-oriented business people believe that the innovation will increase their incomes, Thus innovations that carry high rewards for big agribusiness groups will be adopted even if they harm segments of the population and reduce the availability of food in a country. Further, should s new technology promise to alter substantially the profits and losses associated with any production system, those with economic power will strive to maintain and improve their own positions. Therefore, although technical advances in food production and processing will perhaps be needed to ensure food availability, meeting food needs will depend much more on equalizing economic power among the various segments of the populations within the developing countries themselves.
The author appears to tell us ______.
选项
A、how food industry works
B、how to introduce a new food technology into a developing country
C、key factors of applying technological solutions to the problem of food shortages
D、some food technological innovations
答案
C
解析
主旨题。文章第一段指出过去一些粮食生产新技术半途而废的原因;虽然技术上可行,但不经济或者在文化上让消费者难以接受。第二段对比说明了粮食生产安全性、粮食贮藏的实用性、粮食成本等因素对新技术成功的重要性。第三段则重点讨论了经济因素和政府的粮食政策的重要性。因此不难看出,文章要说明的就是对一种新技术成功很重要的这些因素,因此主旨是C 。
