Unit 12 · Multi-Step Conditional Reasoning
Sports Team — Flip Rule 1, Then Rule 2
Lesson 5 of 16
About this lesson
Two conditional rules, one given fact, and a chain of two deductions. This question is the cleanest example of multi-step conditional reasoning in OC TS: the first step requires using the CONTRAPOSITIVE of a rule (flipping and negating it), and the second step simply applies the second rule directly. Get those two moves in order and the answer is immediate.
