Greetings from ShepHertz!!!!!
There are many ways to achieve this it again depends on your game busniess logic how you want to achieve this.
You can use gameRoom.BroadcastChat function in your RoomAdapter to send questions to all the users in the game.You can write it in onTimerTick function. Player can answer using RoomRPC API so that you can record the same on the server.
You can also send questions to specific user using iUser.SendChatNotification function to send questions to a specific user and using RoomRPC you can record the answers.
You can use only RoomRPC API to send question and for answers on server. You can create to function for that and player can call accordingly.
Let me know if it helps.
