这道PREP的答案是不是有问题

正在做新老PREP，今天遇到了一道题，答案和网上大家讨论的答案不一样，是不是整理PREP的过程中，作者笔误了？

Pioneered by scientists at Los Alamos National Laboratory, BEAM robots are not programmed to walk; instead they use brainlike circuits called neural networks to learn to walk through trial and error.



(A) BEAM robots are not programmed to walk; instead they use brainlike circuits called neural networks to learn to walk through trial and error

(B) BEAM robots learn to walk through trial and error by using brainlike circuits called neural networks instead of by programming them

(C) BEAM robots are not being programmed to walk but instead using brainlike circuits called neural networks and learning to walk through trial and error

(D) brainlike circuits called neural networks are used instead of programming for BEAM robots learning to walk through trial and error

(E) brainlike circuits called neural networks are being used for BEAM robots that learn to walk through trial and error instead of being programmed

应该是A吧？因为很清晰，但是下载的PREP9套题中，答案给的是D

清飞扬

答案是A
