For example, if you chose Carter for Nobel prize first and also pick Nixon for "resigned from office" - then you are left with Ford for "president during 1970s" etc.
Also, I don't think one needs it but the only correct option for Obama is "served two full terms" so that's possibly an alternative route.
When I was making the quiz, I didn't love the "after leaving office" Nobel prize question but it was one of few ways I could ensure quiz had a solution.
I have increased the time limit to 7 minutes.
