Answer: In many ways space science contributed to the realization of important space applications-which may be defined as the use of space knowledge and techniques to attain practical objectives. Indeed, at the start of the program numerous potential applications required much advance research, including some space science, before their development could begin. Moreover, to many persons the development of applications appeared as the ultimate payoff of investments in the space program. Although the scientists would probably not have put it so strongly, nevertheless they could appreciate that point of view. As a consequence space scientists often pointed to potential applications of their work as one of the justifications for giving strong support to science in the space program.
Yet, in pointing to ultimate applications as one of the benefits to expect from their research, the scientists encountered a strange paradox. Although not appreciated for most of the 1960s, it finally became clear that in many respects applications-the "bread-and-butter work" of the space program-found it more difficult to gain support, especially on the executive side of government, than did space science.

Explanation:
The correct answer is letter A
When talking about agricultural production in the feudal world, we soon remember that working on the land sought to meet basic needs. Unlike in other times, medieval agriculture had a low productive performance that limited the occurrence of natural exchanges and trade. In general, this subsistent characteristic is related to the poor quality of the seeds used and the limitation of the instruments and techniques of the time.
Despite the relevance of these factors, we must take into account that the medieval peasants also used the system of crop rotation. In this technique, a lot of arable land was divided into three equivalent portions. In the first two, the servant established the planting of two distinct cultures. The remaining lot was not used, so that the land plot was not completely worn out.
