Hi LSAT Max, Would (E) be incorrect because we cannot make the assumption about permeable skin based off of the stimulus! Thanks in advance!

Hi @Julie-V,

Yup, that's correct. The stimulus doesn't talk about how the actual permeability itself of a frog's skin varies based on its size or other factors, so we can't make inferences about the permeability. As it's presented in the stimulus, small frogs and large frogs differ because of certain surface area ratios, not because of the permeability. Hope this helps!
