Short answer question length

I’m uncertain as to the meaning of the length recommendation for the short answer questions. The guideline says:

“The most effective response typically ranges from 250-500 words in total for all three questions.”

Does this mean that I should have three responses, all of which contain 250-500 words, or that the total length of all my responses combined should be 250-500 words? I would be grateful for clarification.

250-500 total, each about 100 words.

Ah. Thanks!
