Written assignments which are impossible, or very difficult, to use ChatGPT for?

Inspired by a post I saw on r/UniUK ...

What types of written assignments are difficult, or impossible, to solely use ChatGPT for? Or - how can we limit the use of ChatGPT to complete the assignment?

I **don't** mean to stop using ChatGPT to brainstorm ideas. I mean - to stop ChatGPT from writing the whole thing from scratch.

I currently have an infographic assignment (yes, technically not written) which you couldn't use ChatGPT to make for you.

Any other ideas, particularly for traditional written assignments?
