Which sentence in the section "Mouse Brains On Fat And Sugar" BEST supports the inference that unhealthy diets can affect a mouse's ability to survive?

The fatter mice were just as good at swimming; they just did not find their way to the platform.

When they were put in a pool of water and made to find their way by their ability to remember landmarks, the fat mice performed poorly and would have drowned because of the inability of their brains to function well. This was a test of survival.
