问题 The agricultural sciences deal with the challenges of food and fiber production and processing. They include the technologies of soil cultivation, crop cultivation and harvesting, animal husbandry, and the processing of plant and animal products for human consumption and use. As a result of the doubled yields of some economic crops, the farm output per hour of farm work increased almost 10-fold as capital was substituted for labor. New techniques of preserving food products made possible transportation over greater distances, in turn facilitating adjustments among locations of production and consumption, with further benefits to production efficiency.
选项
答案农学(农业科学)研究的对象(探讨的)是粮食和纤维生产与加工所面临的挑战。农学包括耕作和耕种技术、畜牧业技术和动植物消费品加工技术。由于某些经济作物产量的成倍增长，并随着资本取代劳动，每小时农业生产的产值几乎增加了10倍。储存食品(粮食产品)的新技术使长途运输成为可能，这反过来又有助于产地与消费地之间的调整，使生产效率进一步提高。
