@JustAnAce,
Hi fellow Ace!
I'm ace too - so hopefully I can give you a few pointers on how to handle this, as I've come into similar situations.
I noticed you’ve said you’re ace – but I guess I can assume you’re aro (aromantic) too? The reason is I know a fair few ace people that do experience regular romantic attraction. Asexuality being a spectrum means everyone experiences it differently – so do tell me if anything I assume is wrong!
First thing’s first: I think it’s very important to be up front with your teacher about how you feel. I note that you’re still not open about your asexuality (and of course you do NOT have to tell anyone), but it would help if you were up front and said that you are struggling to complete the assignment as you find it difficult to think on such terms. I’m sure the teacher would then be able to give you options as to how to complete the assignment.
I think the proposed variants by izzythepush are good (such as looking at it in a historical context), you could also ask your parents vs. their parents, or your parents vs. your friends to get “general attitudes”, or thinking of what you would like in a friend if it was a platonic-life partner. I know a lot of ace people feel deeply attracted to friends but purely in a friend sense (as in they just want to hang out with them all the time, be friends, get nervous when they’re around. I totally get it, I had so many ‘platonic crushes’ that I didn’t really understand at the time!). I think whatever you propose to do, you should check with your teacher first.
Remember, if the teacher gives you a poor grade based on you not completing it because you’ve been unable to as an ace person, then that is discrimination on the basis of sexuality. Unfortunately the school system is cisheteronormative, and it’s up to people like you and me to argue that such curriculums do not fit our educational needs.
The question does seem unfair to non-cishet people, or people who would be adverse to marriage. It could have definitely be shaped in a different way, or made far less personal so that students aren’t forced to disclose private information.
My DMs are open if you want to send me a private message rather than discuss this privately!
