Chatbot Quiz - Multiple Options Uval Problem

Hi Everyone
I’m creating a quiz bot and some of the questions have multiple answers in the same gambit.
An example of one gambit would be
“select the colours”
-Blue (uval=1)
-Red (uval=1)
-Cat (uval=0)
-Car (uval=0)

The user should select Blue and Red making the uval of the gambit = 2.
Is their a way of doing this? currently when I have two selections it breaks the API math.
