I got the right answer, but took way too long. Could any of you describe the method by which you guys got the answer? I'm also aware of the Powerscore method but can't figure it out.

Thanks, truly appreciated.

Did you try diagramming out the conditional statements (there are 4 presented) and linking them up to see the transitive inferences than can be derived from their combination?

That is a good way to go with a typical conditional reasoning must be true question such as this.
