What happens to a page written in HTML 5 that's viewed in a browser that
only supports HTML 4? For example, what would it do with the AUDIO
element? Are unsupported elements simply ignored?

It depends - on the constructs you use. And there's no browser that
supports HTML 4, though most come close enough for most practical purposes.

It would use the content of the element - technically, AUDIO was
designed so that the content acts as fallback content, though to old
browsers, <audio> tags are just unrecognized tags that they ignore (but
they process whatever is between <audio ...> and </audio> tags).
