I want to check questions for consistency and give feedback for it.
For instance I want to ask how much violence do you think there are in computer games
and give them choices from 1 to 5
and then in a late block I want to ask how much do you think computer games are violence
and again give them choices from 1 to 5

I want to add 1 point to the total score each time such two questions are answered with the same number
if they answered the first question 3 and the second question 3 then they get 1 point
but if they answered the first question 3 and the second question 1 then they get 0 points
