Trying to Get a quiz Game started

Hello I am trying to start a new project and as soon as I start a new project, I set up the scenes, scripts, and prefab folder, then I make the Scenes and place them in the scenes folder, Persistent, MenuScreen, and Game. Then in the Scripts file I make two initial scripts, AnswerData and DataController. I then fill out AnswerData with
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

[System.Serializable]
public class AnswerData {

public string answerText;
public bool isCorrect;
}

Then I go back and start to make QuestionData, but then I look at my AnswerData script and I see No Monobehaviour scripts in the file, etc.
I posted the picture of what I see below. This is not the only time this has popped up. I have restarted this project several times as I cannot figure out why this keeps happening. This did not happen to me when I used MonoDevelop.

What exactly is the issue? Do you want it to be a MonoBehaviour? If so, then make AnswerData extend MonoBehaviour class. If not, you can ignore that text.

Do note that it’s neither a warning nor an error, it has an info icon and it’s simply saying your script does not contain a MonoBehaviour.

EDIT: Also, try creating a script with a MonoBehaviour and e.g. a public field of type GameObject. Then select the script and instead of the info text, it should show the field in which you can assign the default value for that component. When you add that component to a GameObject, those default references will be set for you.
