counting the correct answer per gate

I have 6 gates in my game. Each gate will open if you answered the question asked correctly. Each gate has a script called question1,question2 … question6 and if you collide to the gate, a gui will prompt and a multiple choice question will be asked.

My question here now is how will I be able to count the correct answer coming from each script?
example: if question1 is correct, where should I put the score?

One Script to rule them all, One Script to find them,

One Script to bring them all and in the darkness bind them.

So, LOTR jokes aside, you need a manager which is going to know whose question has been answered. And by the way, all your gates have the same behaviour, so you only need one script with different questions.
