CorrectNot quiteAnswer D
Correct answer: D
Explanation
Violets are lilies and lilies are tulips, so all violets are tulips. Since violets exist, some tulips are violets: this follows.
The tulips that are daisies may or may not include violets or lilies, so 'Some violets are daisies' and 'No lily is a daisy' are only possible.
'All tulips are lilies' reverses an All statement, which is invalid.
So 'Some tulips are violets' is the one that definitely follows.
