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?

• DSelection 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. 分析该选项
• EFarm 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.
• 答案是D，从机器能区分颜色除草来加强的。我选的E，因为文章最后一句话说了机器能减少labor costs。为什么不对呢？

又是你啊小妹妹
原文说的是这个新机器可以减少花在除草上的人工费用
E说的是工人不去除草了去干其他事情，和原文这个费用减少没关系
工人去干别的或者去晒太阳或者去打游戏，对原文这个减少的人工费用有影响吗？没啊
