好吧我看到了gmatclub的解释觉得嗯。是我理解错了。。哎
gmatclub explain:
A.Tells us nothing about the color of the plants (as we are told, the new technology uses differing colors between crops and weeds). The trap - Eliminate
B.Makes the technology non-efficient. Eliminate
C. So what? WE are concerned with the new technology, which uses color to distinguish weeds from crops. WE dont care about manual distinction - Eliminate.
D. Straight Answer. Crops can be bred to have distinct colors, which can enable the technology separate crops from weeds.
E. We are not concerned about manual processes - Eliminate (irrelevant) |
