### Parallel the Reasoning and Principle

I cannot understand how to diagram these out. I look at the ones in the princeton review and the examples they use are way easier than the ones I see on the PT's.

Can someone please explain to me how to diagram a PTR?
Please not an easy one like A->B B->C C->A type I mean the harder confusing ones that are like a paragraph long.

The principle questions too.

Thanks

### Re: Parallel the Reasoning and Principle

It's hard to diagram something without being able to publish it. However, there are certain keywords that indicate necessity and sufficiency. When you're in a question type that lends itself to diagramming (sufficient assumption, parallel, must be true are the top 3), you want to look for those keywords. Take it one statement at a time, making sure to check each one after you're done for accuracy.

Any particular questions from PTs you were having issues with? If you post the test, section, and question, we can probably post a diagram.

Principle questions function like assumption questions, if that helps. You supply the premise that makes the conclusion follow.

Parallel the reasoning is more of an art than I science, I would say. Drill 'em like crazy and you'll figure it out.

Feb 1993 Form 3LSS18 section 4 #25 that would be a great example of a confusing one in how to diagram
