Android Build an Interactive Story App (Retired) User Input Finding Views by IDs

Why is this question in the course right off the start?

I just started the "Build an Interactive Story App" course and I watched the first video. I then moved on to the second step and it was this question:

"Initialize the member variable mExterminateButton using the findViewById() method. The ID for the button is button1. Don't forget to cast the generic View returned by the method!"

Why is this a part of the course right off the start? Was it a test to see if the user watched the "How to make a simple app" course? Is it an error? I answered it right, but it seemed kind of weird.

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MainActivity extends Activity {

    protected Button mExterminateButton;

    public void onCreate(Bundle savedInstanceState) {

        // Declare our view variables

Hi Michael,

In the "Beginner Android Development" track, this course is listed after "Build a Simple Android App".

I don't know if that course was listed as a prerequisite for this course but I think the challenge is assuming a certain level of prerequisite knowledge.
