SEO Test -- Instructions Unclear

Interviewing for an agency position and they've asked me to optimize a blog post for them before the interview. Great, sounds good.

The issue is that part of the instructions are to come up with a focus keyword for the post and h1's, h2's, and h3's, however, it clearly already has a focus keyword and optimized headings. Not really sure how to move forward with that and don't want to ask for clarification and look like a dummy.

Post in comments. Any advice appreciated, thanks!
