TEXT B The promise of finding long term technological solutions to the problem of world food shortage seems difficult to fulfill. Many innovations that were once heavily supported and publicized, such as fish protein concentrate and protein from algae grown on petroleum substrates, have since fallen by the wayside. The proposals themselves were technically feasible but they proved to be economically unviable and to yield food products culturally unacceptable to their consumers. One characteristic common to unsuccessful 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 social cultural system in which it is to find a place. Security of crop yield, practicality of storage, and costs are much more significant than 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 economies of technological innovation. Although they exaggerate in claiming that profitability-is the sky 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 (agricultural business) groups will be adopted even if they harm segments of the population and reduce the availability of food in a country. Further, should a 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 position. Since large segments of the populations of many developing countries are close to the subsistence margin and essentially powerless, they tend to be the losers in this system unless they are aided by a government policy that takes into account the needs of all sectors of the economy. 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 population within the developing countries themselves. Which of the following best describes the organization of the first paragraph

It can be inferred from the passage that the author would be most likely to agree with which of the following statements concerning the solution to food shortages in developing countries

TEXT C Though England was on the whole prosperous and hopeful, though by comparison with her neighbors she enjoyed internal peace, she could not evade the fact that the world of which she formed a part was torn by hatred and strife as fierce as any in human history. Men were still for from recognizing that two religions could exist side by side in the same society; they believed that the toleration of another religion different from their own. And hence necessarily false, must inevitably destroy such a society and bring the souls of all its members into danger of hell. So the struggle went on with increasing fury within each nation to impose a single creed upon every subject, and within the general society of Christendom to impose it upon every nation. In England the Reformers, or Protestants, aided by the power of the Crown, had at this stage triumphed, but over Europe as a whole Rome was beginning to recover some of the ground it had lost after Martin Luther’s revolt in the earlier part of the century. It did this in two ways, by the activities of its missionaries, as in parts of Germany, or by the military might of the Catholic Powers, as in the Low Countries, where the Dutch provinces were sometimes near their last extremity under the pressure of Spanish arms. Against England, the most important of all the Protestant nations to reconquer, military might was not yet possible because the Catholic Powers were too occupied and divided: and so, in the 1570’s Rome bent her efforts, as she had done a thousand years before in the days of Saint Augustine, to win England back by means of her missionaries. These were young Englishmen who had either never given up the old faith, or having done so, had returned to it and felt called to become priests. There being, of course, no Catholic seminaries left in England, they went abroad, at first quite easily, later with difficulty and danger, to study in the English colleges at Dubai or Rome: the former established for the training of ordinary or secular clergy, the other for the member of the. Society of Jesus, commonly known as Jesuits, a new Order established by St. Ignatius Loyola same thirty years before. The seculars came first; they achieved a success which even the most eager could hardly have expected, Cool minded and well-informed men, like Cecil, had long surmised that the conversion of the English people to Protestantism was for from complete; many—Cecil thought even the majority—had conformed out of fear, self-interest or—possibly the commonest reason of all—sheer bewilderment at the rapid changes in doctrine and forms of worship imposed on them in so short a time. Thus it happened that the missionaries found a welcome, not only with the families who had secretly offered them hospitality if they came, but with many others whom their first hosts invited to meet them or passed them on to. They would land at the ports in disguise, as merchants, courtiers or what not, professing some plausible business in the country, and make by devious may for their first house of refuge. There they would administer the Sacraments and preach to the house holds and to such of the neighbors as their hosts trusted and presently go on to some other locality to which they were directed or from which they received a call.
