I may be completely spacing, but I'm going over a Lesson 2 Conditional Reasoning questions (page 2-9), and next to the multiple choice answers are abbreviations for SN and PR. (ie. D (Must be True- PR, SN))

What do these stand for?

Thanks! :-D

Hi Kaquino,

Good question. Those are indicators of two separate things:
  • SN = Sufficient and Necessary conditions are present in the stimulus

    PR = The question stem indicates that a principle must be used.
Others you will see include:
  • CE = Cause and Effect Reasoning is present in the stimulus

    #% = The stimulus features Numbers and Percentages

    FL = The stimulus uses Formal Logic

    X = The question stem contains an Except term

Please let me know if that helps. Thanks!
