Pause scene when character hit object, then resume it from another scene

Hi, I’m developing my Endless Runner 2D game project. My question is how can I make the character hit an object which is a coin and then the entire scene is paused while it go to another scene which is to answer a question with one answer. Then, when the player already choose the correct answer, it will resume the previous scene where the character stopped.

Since I am new, and my game is already finish (I guess…) I’m still stuck with these pause/resume problem.

I hope anybody can help me with these problem. (:

Unfortunately, I do not have such practice in developing characters, now I am practicing 3D development.

In addition, I practice online learning https://edureviewer.com/masterclass-vs-skillshare/ in order to have more time to study 3d graphics. But there is still a lot to do, namely to buy RAM and a powerful video card
