patsy is studying different kinds of weathering. she has four pans full of dried modeling clay. some she adds water to. some she freezes overnight, then lets thaw, as summarized in the table below:

panadded water? froze the pan? 1yesyes2yesno3noyes4nono
then she compares the clay in all four of her pans. the clay in pan #4 was the same at the end of the experiment as it has been at the beginning. the clay in pan #1 had changed and broken up more than the others.

which of the following conclusions could patsy have made?

frozen clay takes up more space than thawed clay does.

adding water to clay and then freezing it breaks the clay apart more than either freezing it or adding water to it alone.

adding water to clay and then freezing it plants to grow in the clay more than either freezing it or adding water to it alone.

wet clay takes up more space than dry clay does.
