Matching answers from different words

Hello. I’m trying to create a course which will have words that should be written with a correct particle after it. It will have such structure:

q1 = “some answer 1”
q2 = “some answer 1”
q3 = “some answer 2”
q4 = “some answer 2”
q5 = “some answer 3”

q80 = “some answer 2”

But when I created such relationships between the words and answers it gives me “wrong answer” each time when the question is repeated in reverse. Like

“some answer 2” doesn’t equal q80,
because “some answer 2” equals q3.

What can be done in this case, how should I structure the course or allow answers to be matched with any other word if it even has the same text in its answer?
