The teacher asked for a one-minute talent show. Is there any quick fix?

I don’t know much, so here are a few:

A little magic or something like that. The basic magic props and techniques are all ready-made, and even if they are exposed, It’s okay, or you can reveal the secret on the spot after your performance

You can sing if you have a slightly better voice, without having a singer-level voice. Nowadays, some singing software can do a good job of mixing and accompanying background sounds

Find a shorter stand-up comedy, or a speech that fits the occasion, to prove that you are good at eloquence, and you can give priority to participate in debates in the future, etc.

It is probably about the same. In fact, many talents can be improved with a little practice. But if you want to get it done quickly, that’s probably all it will take
