题目：

1、When you have a lot of routes that arrive to a different place, and there's one that is the shorter and the faster one, the optimal thing would be to close the rest so you never get lost, from point A to point B.

2、They found that parts of the brain dealing with social cognition actually shrunk reduced in volume-in women who successfully conceived and had kids.

3、That's compared to no changes among control women, and no changes in men-whether they were new fathers or not. Shrinking sounds bad though: why would you want less grey matter?

4、Carmona and her team took MRI scans of 25 women's brains, before and after their first child.

5、But Carmona says less does not result in deficits in thinking or memory, and might actually be the result of a good thing: the fine-tuning of connections between neurons.
