Determine whether each conclusion follows from its premises.
Example 1: every rose is a flower; every flower is part of a plant; therefore every rose is part of a plant. The conclusion follows under these premises.
Example 2: every rose is a flower; jasmine is also a flower; therefore jasmine is a rose. The conclusion does not follow: being a flower is not exclusive to roses.
The central issue is entailment, not attractive phrasing.
