A bit stumped by the Haas Supplemental Information section. What's the expected format here?

Two of the five sections specifically ask for a list - clear enough.

But for the career gaps question, I assume this can be in essay format, correct? There's no word limited specified. I actually have a lot of meaningful stuff to say here (several jobs since college, and gaps were fruitful/ had impact), so am wondering whether 300-400 words is too much.

Thoughts?
