神贴！很多其他帖子都只阐述了练习方法和过程，而楼主的帖子让我感觉GMAT是一种境界！我也是学biochemistry的，大赞！！！

没有办法，姐姐我只能在这里发了。
求教本月JJ GWD原题，请问下面这题为啥选3不选5？？？？看了好多遍，怎么都觉得3是个迷惑选项。文章强调的是生产的产品可以被a single group加工运输出去。而不是说只有垂直经济中可以由a single group完成生产。贸易网络和垂直经济最大的不同，应该是垂直经济更加self-sufficient.急死我了，求姐姐解惑，快想一个小时了。还有，以前没有做过GWD，为什么觉得GWD这篇的题正确选项都很偏呢？考试也会这样吗？非常感谢！！！
By the sixteenth century, the Incas印加人of South America ruled 管辖an empire that extended along the Pacific coast and Andean highlands 安第斯山脉from what is now Ecuador厄瓜多尔 to central Chile智力. While most of the Incas were self-sufficient agriculturists, the inhabitants居民of the highland basins 高源盆地above 9,000 feet were constrained by the kinds of crops they could cultivate. Whereas 95 percent of the principal Andean food crops can be cultivated below 3,000 feet, only 20 percent reproduce readily above 9,000 feet. Given this unequal resource distribution, highland Incas needed access to the products of lower, warmer climatic zones in order to enlarge the variety and quantity of their foodstuffs. In most of the preindustrial 工业化world, the problem of different resource distribution was resolved by long-distance trade networks over which the end consumer exercised little control. Although the peoples of the Andean highlands participated in such networks, they relied primarily on the maintenance of autonomous production forces in as many ecological zones as possible. The commodities商品 produced in these zones were extracted, processed, and transported entirely by members of a single group.
     This strategy of direct access to a maximum number of ecological zones by a single group is called vertical economy. Even today, one can see Andean communities maintaining use rights simultaneously to pasturelands above 12,000 feet, to potato fields in basins over 9,000 feet, and to plots of warm-land crops in regions below 6,000 feet. This strategy has two principal variations. The first is “compressed verticality,垂直压缩” in which a single village resides居住 in a location that permits easy access to closely located ecological zones生态区. Different crop zones or pasturelands are located within a few days walk of the parent community. Community members may reside temporarily临时的 in one of the lower zones to manage the extraction of products unavailable in the homeland. In the second variation, called the “vertical archipelago垂直群岛,” the village exploits resources in widely dispersed分散的 locations, constituting a series of independent production “islands.” In certain pre-Columbian Inca societies, groups were sent from the home territory 地域to establish permanent satellite卫星 communities群落 or colonies in distant tropical forests or coastal locations. There the colonists grew crops and extracted products for their own use and for transshipment back to their high-altitude compatriots同胞. In contrast to the compressed verticality system, in this system, commodities rather than people circulated through the archipelago.

GWD-9-Q6 N-17-Q7:
The passage suggests that as a way of addressing the problem of different resource distribution in the preindustrial world, the practice of vertical economy differed from the use of long-distance trade networks in that vertical economy allowed


1.    commodities to reach the end consumer faster
2.    a wide variety of agricultural goods to reach the end consumer
3.    a single group to maintain control over the production process
4.    greater access to commodities from lower, warmer climatic zones
5.    ！greater use of self-sufficient agricultural techniques
