I'm super confused as to what this task is asking me to do. Could I get some clarification?

I've tried many solutions that are not technically "wrong" but they're not what the task is asking me to do apparently. I feel like I'm making things more complicated than they need to be but that's because I really don't understand what I'm being asked to do.

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.

String response = console.readLine("Do you understand do while loops?");
Boolean answer = (response.equalsIgnoreCase("yes"));
do { 
  response = console.readLine("Do you understand do while loops?");

  if (answer) {
    console.printf("Because you said yes, you passed the test!");
  }
} while (response.equalsIgnoreCase("no"));

Nevermind, figured it out. All I needed to do was write the console.printf using %s and response as a parameter.

This one gets a lot of people.

Challenge 1 "Prompt the user with the question "Do you understand do while loops?" Store the result in a new String variable named response."

String response = console.readLine("Do you understand do/while loops?");

Challenge 2 "Now continually prompt the user in a do while loop. The loop should continue running as long as the response is No. Don't forget to declare response outside of the do while loop."

// I have initialized a java.io.Console for you. It is in a variable named console.

String response = "";

do {
  response = console.readLine("Do you understand do/while loops?");
} while (response == "No");

Challenge 3 "Finally, using console.printf print out a formatted string that says "Because you said <response>, you passed the test!""

console.printf("Because you said %s, you passed the test!", response);
