One in four Americans unaware that Earth revolves around Sun: poll

[HereSince1628]

12. Or is it that 25% of Americans don't know the meaning of 'revolve'?

I haven't seen the quiz but I wonder if it's really a matter of scientific understanding or if instead it's a matter of the depth of an average Americans' vocabulary.

My teaching experience suggests that among entering college students a large percentage don't have particularly advanced vocabularies. It wouldn't surprise me that 25% of American's aren't secure in the meaning of the word "revolve". Rotate and revolve are easily confused...the spin of electric motors is discussed in terms of 'revolutions' per minute rather than rotations per minute.

I wonder where that 25% Americans' made their mistake on the quiz--lack of awareness that the earth orbits the sun...or lack of awareness that with respect to our planet, orbit and revolve are related concepts?
