Setting up Jump trigger

Hi, i have been setting up a jump trigger in my gamemanager script for my character to jump when i answer correctly a T/F question. but i don't know how to set a reference for the jump trigger on the character control script

//GameManagerScript

using System.Collections; using System.Collections.Generic; using UnityEngine; using System.Linq; using UnityEngine.UI; using UnityEngine.SceneManagement;

public class GameManager1 : MonoBehaviour { public bool answer = false; public Question[] questions; private static List unansweredQuestions;

 public Question currentQuestion;

 [SerializeField]
 private Text questionText;

 [SerializeField]
 private Text trueAnswerText;
 [SerializeField]
 private Text falseAnswerText;

 [SerializeField]
 Animator animator;
 [SerializeField]
 Animator anim;


 [SerializeField]
 private float timeBetweenQuestions = 1f;

 void Start()
 {
     answer = false;

     if (unansweredQuestions == null || unansweredQuestions.Count == 0)
     {
         unansweredQuestions = questions.ToList<Question>();
     }

     SetCurrentQuestion();

 }

 void SetCurrentQuestion()
 {
     int randomQuestionIndex = Random.Range(0, unansweredQuestions.Count);
     currentQuestion = unansweredQuestions[randomQuestionIndex];

     questionText.text = currentQuestion.question;

     if(currentQuestion.isTrue)
     {
         trueAnswerText.text = "Correct";
         falseAnswerText.text = "Wrong";
     }
     else
     {
         trueAnswerText.text = "Wrong";
         falseAnswerText.text = "Correct";
     }

     
 }

 IEnumerator TransitionToNextQuestion ()
 {
     unansweredQuestions.Remove(currentQuestion);

     yield return new WaitForSeconds(timeBetweenQuestions);

     SceneManager.LoadScene("Quiz");

 }

 public void UserSelectTrue ()
 {
     animator.SetTrigger("True");
     if (currentQuestion.isTrue)
     {
         Debug.Log("Correct!");
         answer = true;
     }
     else
     {
         Debug.Log("Wrong!");
         answer = false;
     }

     StartCoroutine(TransitionToNextQuestion());
 }

 public void UserSelectFalse()
 {
     animator.SetTrigger("False");
     if (!currentQuestion.isTrue)
     {
         Debug.Log("Correct!");
         answer = true;
     }
     else
     {
         Debug.Log("Wrong!");
         answer = false;
     }

     StartCoroutine(TransitionToNextQuestion());
 }
 void Update()
 {
     if(answer == true)
     {
         anim.SetTrigger("Jump");
     }
 }

}

. //Player Control Script using System.Collections; using System.Collections.Generic; using UnityEngine;

 public class PlayerControlls : MonoBehaviour {
 
     public GameManager1 GM1;
     public float jumpForce;
 
    //set a trigger for jumping//

     // Use this for initialization
     void Start () {
         theRB = GetComponent<Rigidbody2D>(); 
     }
     
     // Update is called once per frame
     void Update () {
 
         isGrounded = Physics2D.OverlapCircle(groundCheckPoint.position, groundCheckRadius, whatIsGround);
 
         if (GM1.answer == true)// This action should activate when Answer of Quiz is correct
         {
             theRB.velocity = new Vector2(theRB.velocity.x, jumpForce);
         }
     }
