Spoilers!
My system locked up and threw me out of the CSM page at #43. I didn't feel like cycling through the whole list just to get to where I stopped. At that point I had missed one, but I'll give myself a do-over credit for that because I knew perfectly well Titan had liquid hydrocarbons on its surface, but I thought "water" instead of "liquid" when I read the choices.
To be honest, there were three or four I guessed at, but I got lucky because I was able to rule out one or two of the other options up front.
The one that gave me the most trouble was the F to C conversion. I derived the equation for freezing point, but couldn't logic it out, I actually had to solve it algebraically. In a way, that is cheating.
