Show answer & explanation
Correct answer: D
Contrary propositions are those propositions which cannot both be true at the same time, but both can be false.
In traditional logic:
Universal Affirmative (A-type): “All poets are dreamers”
Universal Negative (E-type): “No poets are dreamers”
These two propositions are called contrary propositions.
Therefore, the correct answer is:
A. All poets are dreamers
E. No poets are dreamers
