OK so I have a similar but different issue. Sample question....
List the first two letters of the alphabet in any order.
I would like to do a cloze question where the first space would accept A or B; however the second slot would only mark the one not used in the first slot as correct. So:
A:A - 50%
A:B - 100%
B:B - 50%
B:A - 100%
B or A: blank - 50%
Is this possible
