rather than requiring you to write a long response, i think it just means that they want you to write
no more than one page ...
in other words, i am reading the instructions as "it's really up to you, whether or not you want to write just a small paragraph or to fill up the whole page. just don't go over a page... or else!!

"
j/k... In my opinion, as long as we get our point across we'll be just fine.
