This may make you feel like a genius

I was watching Who Wants to be a Millionaire, and one of the first, simple questions was:

Which of the following oceans is NOT crossed by the equator?

a) Atlantic
b) Pacific
c) Indian
d) Arctic

Amazingly, the contestant is stumped and blurts out "I'm not good at geography", then with just two seconds left on the clock, she says she wants to "Ask the audience".

How bad does one have to be at geography to not be able to answer this question? Think about it. One would have to either not have any idea where the equator is or think that the Arctic Ocean is possibly somewhere around the centre of the earth.
