Which of the following is NOT true about the brain's executive function? ( )

参考解析：

是非题。根据题干关键词brain's executive function可以定位到原文的第四段和第五段，brain's so-called executive function—a command system（对应C项） that directs the attention processes（对应D项）that we use for planning, solving problems, and performing various other mentally demanding tasks. These processes include the ability to ignore distractions to stay focused（对应A项）, switching attention willfully from one thing to another, and holding information in the mind—like remembering a sequence of directions while driving. B项虽然在最后一句话中出现过，但是那只是作者为前面一句话做了类比，like（就好像是），并不是executive function本身的内容，所以答案选B。
