请NN帮忙用helr的分类方法看看gwd一道cr题～～

看过前人的一些讨论帖，都是从每个选项的字面意思去分析对错。看完helr的分类方法后觉得很科学，如果熟练了在考场上能节省不少时间，所以在练习他的分类思维，想看看能不能用他的分类方法用CQ来解释这道题。我分析题目觉得这题属于方案模式推理，不知道是对是错，还请NN们指导一下，十分感激～

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?

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.

正确答案是d

是的。是方案推理。这个题目其实OG Verbal分册上也有。
目标是：to reduce labor cost
方案是：用这个机器
不过需要注意的是，此时这个机器是一个用颜色不同的原理而制造成的机器，所以答案选项中，若想和方案有关系，必然要和颜色有关系。
所以，ABD是可以考虑的。但是，AB选项都是略微的削弱，D选项其实说的是方案的可行性问题。若可以改变颜色，那么就表示方案更容易达成目标。

Hope that helps~
