Although enumerate has overtones of numeric order because of its etymology, it is not so restricted in its use:

Because bullet points list items ...
Is it correct to say:
Please tell us the best choice, and why/why is that?
Tell me your name, and where are you from?

The role here is to be a shortened version of "the fact/idea that...".
The fact that this can be said with such certainty reflects the number and diversity of approaches being taken.
The idea that my drawing of a cat can be mistaken as a bird is proposterous. You must be joking.
Which can also be said as:

You have two independent clauses—one imperative, one interrogative—that, when coordinated, fight for sentence-ending punctuation.
