I've been getting 4 answers correct instead of 5

/*

1. Create a quiz that asks 5 questions.

2. Keep track of the number of questions the answer used correctly.

3. Provide a final message after the quiz letting the user know the number of questions he or she got right.

4. Rank the player. Five questions answered correctly is a gold crown, three to four questions answered correctly is a silver crown, one to two questions answered correctly is a bronze crown, and zero questions answered correctly is no crown at all. */
