Question

Which is the best conclusion about Carmen’s sample?

It is a liquid because it is clear.
It is a liquid because it flows.
It is a solid because it is thick.
It is a solid because it smells sour.

Answer 1

The best conclusion about Carmen’s sample is: It is a liquid because it flows.

Although it is clear and smells sour, the key characteristic that indicates it is a liquid is its ability to flow when poured. The thickness of the sample does not necessarily mean it is a solid; many liquids can be thick yet still flow.
