Aristotle came first

One of my searches came up with a link to the "Ethical Philosophical Selector":

These questions reflect the dilemmas that have captured the attention of history’s most significant ethical philosophers. Answer the questions as best you can. When you’re finished answering the questions, press "Select Philosophy" to generate your customized match of ethical philosophers/philosophies. The list orders the philosophers/philosophies according to their compatibility with your expressed opinions on ethics.

I tried the link and found my results were Aristotle 100%, Ayn Rand only 92%... There were twelve questions, so I guessed that only one answer had been assesessed as inconsistent with Objectivism. That turned out to be question No. 7:

UNIVERSAL LAW
Should I act as if the maxim (principle) with which I act were to become the universal law for all rational people?

The options were

a) Yes, and any deviation from this rule is wrong.
b) Yes, but in a very loose manner, evaluating the unique specifics of the situation is essential.
c) No, there is a consistent morality that applies to all, but their methods may differ greatly.
d) No, one's own actions are not morally equivalent to the actions of others.
e) Doesn't matter/Dislike all answer choices.

and I chose (b) the first time round, having in mind something like the importance of context. Choosing (a) the second time around gave AR 100%, Ari 95%, and Aquinas 83%.
