Restricting types of question

I made a language course but its’ based on rules not vocabulary
Words ending in o – Masculine
Words ending in a – Feminine
Words ending in r – Maculine

…and so on. I want the user to ONLY be prompted with a phrase on the left and have to answer with the choice of rule on the right, instead of being given a word like “masculine” and having to pick out the rule in words.
Is this possible? I wondered if maybe I should put it in a different category instead of languages, for example…?
