Solving Justify the Conclusion questions

Postby mistd » Tue May 21, 2013 12:04 pm

So I know that when the premise and the conclusion have the same necessary condition, you need something linking the two sufficient conditions. For example:

Premise A --> B
Conclusion C --> B

Answer: C --> A

But why is it C --> A and not A --> C?

I've been trying to figure it out but I can't get the logic behind it, forcing me to rely on a mechanistic approach without knowing why I'm getting the answers correct.

Thank you in advance!
