有人回答这个简单的问题吗？

Pioneered by scientists at Los Alamos National Laboratory, BEAM roborts are not programmed to walk; instead they use brainlike circuts 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

为什么D和E的brainlike circuits 就不能被pioneered呢？

circuit 不能被 programming,

而且文章重要强调的是they use brainlike circuts called neural networks to learn to walk through trial and error,不是circut是什么
