That's our code for Conditional Reasoning, ridolph.lauren, and it stands for "Sufficient and Necessary." We could have also used CR, but then it might get easily confused for Causal Reasoning, which we code as CE (Cause and Effect) in our analytics.

So, when you see a question explanation or analysis in your practice with an SN next to it, just know that it means the question involved some use of conditional reasoning!
