'All squares are rectangles; this shape is not a rectangle, so it is not a square.' Which argument uses the same pattern of reasoning?
ASome birds fly; this flies, so it must be a bird
BNo fish are mammals; this is a fish, so it swims
CAll cats are animals; this is an animal, so it is a cat
DAll poets are writers; she is not a writer, so she is not a poet
Answer & Solution
Correct answer: D. All poets are writers; she is not a writer, so she is not a poet
The original is 'All A are B; not B; so not A' (valid contrapositive). The poets/writers option mirrors it exactly.
