I'm working my way through the LR Bible right now, and I just finished the chapter on conditional reasoning. I have a few questions about diagramming:
1. Do you guys diagram each potential answer choice when looking for a contrapositive or repeat diagram? When you find it do you stop or do all five?
2. How long did this take you at the beginning? What about after you had practiced it?
It seems this technique would really increase your chances of getting the question correct, but it also seems like it could be time consuming. Any hints?
