Totally agree - and this was true of a number of the questions on the quiz.
As for the "public goods" question, government financing is not part of that definition. Non-excludability (the correct answer on the quiz,) is. The air we breathe is a public good.
As I mentioned earlier, whether or not something is a public good ought to be one criterion for justifying public funding (not sufficient, but necessary.) But the fact that tax dollars paid for flood control levees or national defense in no way makes them public goods, or else every frivolous, wasteful and unconstitutional government program would be a public good - and they are not.
I also agree that many of these questions are best as measures of test-taking ability, and some are phrased awkwardly.
But on "public good" as I said before, I'm still more right with the alternate bad answer they provided, nor did you reply to the point I raised against the definition of public good you are applying, or the one they are applying.
Here's another reason I am right on this one:
