Answer 1

Granite is more dense than sand.

Answer 2

Exactly, how I answered the question. Would you say this is answered incorrectly in the text?

Answer 3

I'm sorry, I gave the answer, "Granite is more dense than sand." It was marked as incorrect, I feel this must be an error. Thank you once again!

Answer 4

How does your text define "falsifiable claim?"

Answer 5

A claim is also said to be falsifiable, in that it could turn out actually to be false, and we know how that might be shown. For instance, "There are no wild kangaroos in Georgia" is a falsifiable claim; if we went to Georgia and found some wild kangaroos, we would have shown it to be false. But what if someone claimed that there are unicorns in North Carolina, but that they are invisible? Could we ever show such a thing to be false? It would seem to be the kind of claim that cannot be shown to be false, and so is said to be unfalsifiable

Answer 6

Thanks. I agree that our answer about granite is the only nonfalsifiable claim.
