Which of the following is a consideration in favor of the company's implementing its plan to develop the prototype?
【选项】There is a considerable degree of variation in shade of color between weeds of different species.
看题不仔细,这里说的是variation in shade of color between weeds of different species,是杂草的颜色有不同,而不是杂草和植物
这说明的是不同weed 之间的shade 颜色不同 那么反而加大了 区分weed y与 crop 的难度 实际上削弱
A实际上是削弱,因为color 变化的degree增加,使机器的效率降低,人工的效率相对增加,所以可能导致人工成本不能被减少
This reasoning line is that as this machine can depend on different in shade of color to distinguish weeds from corps, it will reduce the labor cost. Thus, the key point is the efficiency of the method of machine, that is, if there is a big difference between weeds and crops. But this option only refers to the differences among weeds.
between weeds of different species 无关;且就算是有关,也是削弱
variation in shade of color between weeds of different species 想当然了。这里说的是weeds之间的颜色差很大,而不是weeds和plants之间的颜色差大,有可能削弱方案。
原文说这个机器通过不同的阴影颜色来区分粮食作物和杂草。而这个选项说不同种类的杂草的阴影颜色有很大不同。管你不同种类的杂草是否能区分呢,只要把粮食和杂草区分来就行了,不关不同种类杂草的事情,无关选项
weaken:说weed之间的shade差异很大,就增加了机器识别的难度
题干重点在于:distinguish weeds from crop,而选项重点是在于variation in shade of color between weeds of different species。明显不同
between weeds of different species,增加了辨别的难度,所以是削弱不是in favor
这句话说的是,不同的杂草种类有不同的颜色。它顶多也就影响机器对杂草种类的辨别而已,不会影响杂草和作物的辨别,并没有什么关系。
weeds of different species. 错误,其实是削弱,加大了distinguish的难度
