This is someone great at seeing " logical relationships among actions or symbols" .

这类人非常善于发现“运动之间或者符号之间的逻辑关系”。

This second function sets up a logical relationship where performing a process on the input has corresponding effects on its mapped output.

第二个函数建立了一种逻辑关系，在这种关系中，对输入执行一个过程会对其映射的输出产生相应的影响。

But if we think of functions as bridges between two groups, we can start to make claims about the logical relationships between them.

但是，如果我们将功能视为两组之间的桥梁，我们就可以开始对它们之间的逻辑关系提出主张。
