GWD1-Q33:

A company plans to develop a prototype weeding machine that uses cutting blades with optical sensors and microprocessors that distinguish weeds from crop plants by differences in shade of color.  The inventor of the machine claims that it will reduce labor costs by virtually eliminating the need for manual weeding.

Which of the following is a consideration in favor of the company’s implementing its plan to develop the prototype?E(D)

A.      There is a considerable degree of variation in shade of color between weeds of different species.

B.       The shade of color of some plants tends to change appreciably over the course of their growing season.

C.      When crops are weeded manually, overall size and leaf shape are taken into account in distinguishing crop plants from weeds.

D.      Selection and genetic manipulation allow plants of virtually any species to be economically bred to have a distinctive shade of color without altering their other characteristics.

E.       Farm laborers who are responsible for the manual weeding of crops carry out other agricultural duties at times in the growing season when extensive weeding is not necessary.

GWD3-Q32:

Newspaper editorial:

In an attempt to reduce the crime rate, the governor is getting tough on criminals and making prison conditions harsher.  Part of this effort has been to deny inmates the access (that) they formerly had to college-level courses.  However, this action is clearly counter to the governor’s ultimate goal, since after being released form prison, inmates who had taken such courses committed far fewer crimes overall than other inmates.
            

Which of the following is an assumption on which the argument depends?D（C）

A.      Not being able to take college-level courses while in prison is unlikely to deter anyone from a crime that he or she might otherwise have committed.

B.       Former inmates are no more likely to commit crimes than are members of the general population.

C.      The group of inmates who chose to take college-level courses were not already less likely than other inmates to commit crimes after being released.

D.      Taking high school level courses in prison has less effect on an inmate’s subsequent behavior than taking college-level courses does.

E.       The governor’s ultimate goal actually is to gain popularity by convincing people that something effective is being done about crime.

你是想听自己为什么选错 还是 答案为什么对呢，  我只解释答案为什么对好了

1 题，  说颜色区分割草机这个东西可以节省人力成本，

        问题：　哪个选项支持割草机计划

　　　　D , 一种技术使得颜色的区分成为可能，  那么是不是用颜色区分式割草机就很可行了呢，  肯定了计划

2 题，  说减弱监狱条件， 取消了原本可以使犯人从善的大学教育。

        问题， 哪一项是假设

        C 说，不会有这么个可能，这个从善，不是大学教育引起的，而是本来他们就善，所以才肯学大学教育的。

        C就对了贝， 取非削弱
