Hmm, I'm not totally sure about this one. I know Maslow's hierarchy has different levels, but I can't quite remember which level water, food, rest, and shelter would fall under. I'll have to think this through carefully.

Hmm, I'm not entirely sure about this one. I know service-oriented architecture is supposed to be vendor-neutral, but I want to double-check my understanding before selecting an answer.
