Changing the UI Text

So I want to update the gui when a question is answered. i looked up a tutorial however the guy in the tutorial reloads the entire scene. What I'm trying to do is to update the gui text with a different question. The code I used is below

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using System.Linq;
 using UnityEngine.UI;
 using UnityEngine.SceneManagement;
 
 public class GameManager : MonoBehaviour {
 
     public Question[] questions;
     private static List<Question> unansweredQuestions;
 
     private Question currentQuestion;
 
     [SerializeField]
     private Text factText;
 
     [SerializeField]
     private float timeBetweenQuestions = 1f;
 
     void Start()
     {
        if (unansweredQuestions == null || unansweredQuestions.Count == 0)
         {
             unansweredQuestions = questions.ToList<Question>();
         }
 
         getRandomQuestion();
     }
 
     void getRandomQuestion()
     {
         int randomQuestionIndex = Random.Range(0, unansweredQuestions.Count);
         currentQuestion = unansweredQuestions[randomQuestionIndex];
 
         factText.text = currentQuestion.fact;
 
     }

     IEnumerator TransisitionToNextQuestion()
     {
         unansweredQuestions.Remove(currentQuestion);
 
         yield return new WaitForSeconds(timeBetweenQuestions);
 
         //Where i think the code should be put to change the text around
 
     }
 
     public void UserSelectTrue()
     {
         if (currentQuestion.isTrue)
         {
             Debug.Log("CORRECT!");
         }
         else
         {
             Debug.Log("FOUT!");
         }
 
         StartCoroutine(TransisitionToNextQuestion());
     }
 
     public void UserSelectFalse()
     {
         if (!currentQuestion.isTrue)
         {
             Debug.Log("CORRECT!");
         }
         else
         {
             Debug.Log("FOUT!");
         }
 
         StartCoroutine(TransisitionToNextQuestion());
     }
 
 }
