Sufficient Assumption question
https://classic.7sage.com/lsat_explanations/lsat-48-section-4-question-21/
Under the timed condition, I got this question right by diagramming as follows:
Context: Ignore unpleasant realities and tell small lies (A) → Sincerity (/B) (B → /A)
Premise: Succeed (C) → Trust (D)
Conclusion: Succeed (C) → face unpleasant realities and speak about them honestly (/A) (ignore unpleasant realities and tell small lies)
Answer choice
(A): D → B
So I picked (A) and moved on.
However, when I was BRing, I got confused by the first sentence:
"Traditional norms (...) prevent sincerity by requiring one to ignore unpleasant realities and tell small lies."
Because of the word "require," I thought I should diagram as
(1) Sincerity (/B) → Ignore unpleasant realities and tell small lies (A) (/B → A)
(Basically this means if you want to prevent sincerity you have to ignore unpleasant realities and tell small lies.)
Since I couldn't connect the chains, I thought again and thought I was right diagramming as follows:
(2) Ignore unpleasant realities and tell small lies (A) → Sincerity (/B) (B → /A)
(If you ignore unpleasant realities and tell small lies, you can prevent sincerity)
But is (2) the right way to diagram this? Is it correct to think that "by" is a sufficient condition indicator? :(
Any help would be very much appreciated!!

A small note on this I saw on another forum:
Either [ignore unpleasant realities] or [tell small lies] would be sufficient to prevent S:
[IGN UR] or [TSL] → SINC
Hence,
SINC → [IGN UR] and [TSL]
Thank you!
I think your issue might be that you are incorrectly tying "requiring" to "prevent sincerity" rather than "Traditional norms in our society". The way I read it is, "Traditional norms in our society require one to ignore unpleasant realities and tell small lies(B), which has the byproduct of preventing sincerity(A)." Which would make B a sufficient condition for A, not a necessary one.
Bumping so more people can see!
