This is the explanation to the passage of the question, which I understand, can make sense of and agree with: "If the flowers Drew got today had been sent by someone who knows him, he would have got violets instead of roses; yet it the flowers had been sent to someone who does not know Drew, he would have received a card, but none came. Therefore the florist made a mistake."
However, the part that explains the answer choice does not make sense to me at all; here it is: "(B) is correct. This argument states that Drew prefers violets to roses. Thus, if one desired to please Drew, one would send violets. Yet it states nothing about what one would do if one desired to do something other than please."
The passage says nor implies that the person giving Drew flowers desires NOT to please. I mean, there is just nothing in the passage to indicate that the person did not want to please.
If someone could explain what I am missing or simply explain it in another way, I would be more than grateful.
Thanks!
