Hey guys thought we could start a list of different/unique ways we've seen this common flaw described in the answer choices. These flaws are so easy to spot sometimes the challenge is wading through how the answer choice obscurely describes them. One that I came across for the first time was the following:

the conditional statement was
A-->B
B
therefore A

the correct answer choice was worded: fails to consider that there are conditions necessary for A in addition to the presence of B

If you guys have any others, please share!
