Uroshoil only causes rashes to humans, not other animals. Therefore, the presence of uroshoil is probably not as a chemical defense in these plants. We are to support thisargument.

A. Wood rats build their nests using dead, brittle branches, not liveones.
This is weakening theargument.

B. A number of different animals use poison oak and poison ivy as foodsources.
Correct. These plants are being eaten by these animals yet the plants didn't 'evolve' anything in them that might prevent the plants from beingeaten.

Took me a while, but this statement adds nothing to the argument really.
