Hi Marissa, thanks for the question.

This passage uses a combination of sufficient/necessary and quantifier statements.

The premises combine to be: T -some- GP -> NOT Poison Fang
It concludes: T -some- NOT Poison Fang

The argument is good and we need to find the answer choice that uses the same reasoning.

Answer choice A:

Collection -some- RM

PbyS -> Not RM ( RM -> NOT PbyS)

Which gives us: Collection -some- RM -> NOT PbyS

This is the conclusion of the argument. Some of the poems in the collection were not PbyS.

This is the exact parallel of the passage.

I hope this helps. Please let me know if you have any other questions.
