How you did:
Great job! You got every question right.
The complaint that "this material isn't relevant to what an adult needs to know" is a bit specious. Three hundred years ago, educated people learned classical Latin and Greek, not so that they could converse with other well-educated people and tell inside jokes, but because it was an intellectual exercise. It doesn't matter the specifics of the exercise, they could have also learned Yoruba or how to solve polynomials in non-commutative rings. What intellectual exercises do is to separate the dumb {insert picture of Dubya here} from those who can learn and solve problems. This is necessary in a meritocracy so that the stupid are not making decisions that the rest of the society has to follow.
What it also shows is that the US is not a meritocracy, but rather a greed-ocracy, where the greediest are making the decisions for everyone else. Not a 100% greed-ocracy though, because there are those that are motivated by fear of criticism {Kathleen Sebelius} who overrule the recommendation of accomplished scientists because they might be yelled at.
