Two common words..wastes time as one assumes there are more. Capitals of countries or capitals of US states- a bit vague. It would be more fun with columns of categories?
Agree, wasn't sure what kind of capitals I was guessing. Other than that, really great idea for a quiz! Really makes you think. Also, I typed "car" by mistake when I meant to type something else, and it took it, and I spend a good minute trying to make sense of how the word "car" could possibly be one of the most common words. Then realized it was THE C.A.R. when I went to type the country in and already had it on my list..
