Dear LSAT Bible Team

Scenario 1. If He only lived in my body, he would not have said that

Scenario 2. I am a self-starting person if necessary

In these two scenarios, what would be the sufficient and necessary condition.

Thank you so much as always

Hi lathlee,

Thanks for the question! Can I ask what brought these examples up for you? Sometimes, context can help us provide a more thorough answer. :)

Anyway, here's the answer you asked for. In scenario 1, "he lived in my body" is sufficient, and "he would not have said that" is necessary. However, this is an odd statement to diagram using SN reasoning, partially because of the past tense (i.e., the contrapositive would almost require you to make this present/future tense).

For scenario 2, this is arguably not conditional reasoning. To make it conditional reasoning, the sufficient condition would be "it is necessary to be a self-starting person" and the necessary condition would be "I am a self-starting person."

I hope that helps!
