    for the first sentence isn’t the unpleasant realities and tell small lies be in the NA condition ? Because it comes after “require”?

      Think about what the sentence is saying. It’s saying that we’re not achieving sincerity when we’re ignoring unpleasant realities and telling small lies.

      So, if you “ignore realities and tell small lies” -> NOT sincerity.

      That’s the sentence as it’s written in the stimulus.

      We can also take the contrapositive. This is likely what you’re thinking about (since the necessary condition goes on the right).

      If sincerity -> you must NOT “ignore unpleasant realities and tell small lies”.

      Graeme has written both in his explanation. Hope that helps! Let me know if you have further questions.
