在GMAT考试中最让大家叫苦不迭的莫过于
Suncrop, a new corporation with limited funds, has been clearing large sections of the tropical Amazon forest for cattle ranching. This practice continues even though
Suncrop，一个新的资金有限的公司，清理了一大块亚马逊热带雨林的地方用于经营畜牧业。这一行为在继续，尽管更大的利润可以被获得通过开发橡胶，该方式不损害雨林，而畜牧业损害雨林。
Which of the following, if true, most helps to explain why Suncrop has been pursuing the less profitable of the two economic activities mentioned above?
下列哪个选项如果正确，最有效地解释了为什么Suncrop选择上述两个经济活动中获利更少的那个?
A. The soil of the Amazon forest is very rich in nutrients that are important in the development of grazing lands."
亚马逊雨林的土地有利于牧草草场的生长的营养丰富。
B. Cattle-ranching operations that are located in tropical climates are more profitable than cattle-ranching operations that are located in cold-weather climates.
热带气候区的畜牧业公司比寒冷气候地区的畜牧业公司更盈利。
C. In certain districts, profits made from cattle ranching are more heavily taxed than profits made from any other industry.
在某些地区，畜牧业获利的税收比其他工业更重。
D. Some of the cattle that are raised on land cleared in the Amazon are killed by wildcats.!
E. The amount of money required to begin a rubber tapping operation is twice as high as the amount needed to begin a cattle ranch.
开始橡胶开发作业的初始资金需求是开始畜牧业的两倍。
解析：
A. 易错项。选项确实给了个理由在解释为什么畜牧业有利可图，但是文章说得很明白，橡胶开发的利润是大于畜牧业的，不能解释为什么选择利润相对少的畜牧业。
(要解释的不是为什么开发畜牧业，而是为什么和利润更高的橡胶开发业相比，还是要选择开发畜牧业)
B. 文章只关心热带地区公司，和寒冷地区公司不相关，选项里的比较没有意义。
C.畜牧业税收重，更不应该选择畜牧业，不能解释为什么选择。
D.那畜牧业应该利润更小。和C一样，说反了，不能解释。
E.正确答案。启动资金少，所以选择畜牧业，尽管它的利润少。而且文章说的很清楚，这个公司资金是有限的。所以很可能没有足够多的资金用于建立橡胶开发。
思路：解释题文章中出现比较，选项中往往出现相关比较。
