选项 A.channel
B.condition
C.sequence
D.process
答案 B
解析 上下文语义衔接+名词辨析本句句意为“思考本质上是大脑进行各个神经元链接的_____。”首先，空格处需要一名词，做表语，而且被of making connections修饰。其次，文中下一句是对这种making connections的阐释和分析，因此只有process（过程）符合句意，故B为正确答案。选项A channel侧重于指某种渠道，原文并没有提及。选项C sequence指的是次序，指一系列的东西按照序列进行排列，原文中并没有强调神经元连接的次序问题。选项D condition指的是条件、状况，文中没有指出思考是构建连接的条件或者状况。因此可排除ACD。
