Why so much variables?

alert('FILL IN THE BLANKS.');
questions = [
  ['Malcom ___', 'X'],
  ['Martin Luther ___ Jr', 'King'],
  ['Elijah ___', 'Muhammad']
]

correctAnswers = 0;
wrongAnswers = 0;

function print(message) {
  document.write(message);
}


for ( let i = 0; i < questions.length; i++) {
  ask = prompt(questions[i][0]);
  if ( ask = questions[1] ) {
    correctAnswers++;
  } else {
    wrongAnswers++;
  }
}

print("<h1>You got " + correctAnswers + " correct</h1>");
print("<h1>You got " + wrongAnswers + " wrong</h1>");

I see a reasonably concise program with an appropriate complement of variables. Maybe you could explain why the variables seem excessive. Can you refactor the code so it still works the same but doesn't need the variables?

That is my code. However, I asked this question before seeing the second part of the challenge. In the second part of the challenge, the extra variables by the instructor totally made sense.
