So by demonstrating a 95% confidence interval for each question, your plan is to circumvent the instructions by showing 0% confidence for all but one of them and 100% for one of them? I bet that's why they start with "If you did the exercise correctly..." because the questions are specifically asking for 95% confidence for each of the 20 questions. Your solution only works if you completely ignore that one instruction that appears in each of the 20 questions. Given that each question individually specifies "95% confidence interval:" in front of each input individually, it suggests that your solution is "kind of dumb" because you are absolutely NOT doing "the exercise correctly..." Your answer for the question asked in this post is "no" because you clearly do not understand what a 95% confidence interval is." Calling it dumb was not as appropriate as you may have thought before replying. Your solution was not clever, as it was completely incorrect.
