Step 1 :This is a problem of permutations. Since each question has 4 possible answers, and there are 5 questions, the total number of ways to mark the answers is \(4^5\).
Step 2 :The total number of ways to mark the answers is \(4^5 = 1024\).
Step 3 :Final Answer: There are \(\boxed{1024}\) different ways to mark the answers.
