Week 10 Synthesis: The Principle & Parallel Family
Week 10 Synthesis: The Principle & Parallel Family
Principle and Parallel both ask you to abstract away from topic and match on structure or rule — the last of the LR "matching" skills before Week 11 pushes into harder, denser material.
Decision Matrix
| Type | What's matched |
|---|---|
| Principle-Identify | Case → general rule |
| Principle-Apply | Rule → matching case, all conditions satisfied |
| Parallel Reasoning | Argument structure, topic-independent |
| Parallel Flaw | Structure AND the specific logical error |

Q1. A Parallel Reasoning stimulus draws an invalid conclusion via a mistaken reversal. Should the correct parallel answer also draw a valid or invalid conclusion?
Week 11 tackles the hardest material directly: nested conditionals, advanced causal reasoning across question types, and EXCEPT/LEAST stem traps.
