Title: Logical Arguments and Deductive Reasoning (Trello Card #427 https://trello.com/card/logical-arguments-and-deductive-reasoning/4d87e664967a0775082939ab/427#)

This is the first exercise I have developed. All feedback is appreciated.

There are two problem types as described in Ben Eater's Google doc: https://docs.google.com/open?id=1sK0n96LsgMte_RL1y2ZXKbR8TF7nhTvpkJdvIP1oDnw8Cm-Lp58gr1MgmXLq

I attempted to make each problem type more dynamic. The first type is comprised of 6 problems, each of which has four different cases (24 total probs). The second type is comprised of 8 problems, each of which has four different cases (32 total probs). Also, since radio buttons are used for answer choices, I also tried to vary that up a bit. Even getting the same problem multiple times will likely have different answers to pick from (the correct answer always being included of course :-)

Making the second problem type more dynamic was complicated, so I included a link to a diagram that explains it in the code. Here is that link: http://dl.dropbox.com/u/35759231/images/law_of_syllogism.PNG

I'll put the sandbox link in in a sec...
