Reset Button with a Multiple Choice (List Picker) Quiz App

I have a quiz app with two screens. My first screen is the whole quiz and I was wondering how I can use a restart button to reset the Quiz. I do not want to open another screen. I want to stay on screen one but just restart the screen as if I was clicking "Refresh Companion Screen". Thanks!

in such case just update all global variable or reset to its initialised values. that be your simple work. Create one procedure and add these things, when refresh button clicked or timer ticks just call this procedure

What does it mean to update all global variables?

just set everthing which needs a reset for your quiz to its initial state
in my quiz example App Inventor Tutorials and Examples: Advanced Features | Pura Vida Apps it is like this
