When answering this question, you can discuss both sides. On one hand, having many subjects can help students gain a broad knowledge base and develop different skills, which is useful for their future. On the other hand, too many subjects might make students feel overwhelmed and stressed, leaving them with less time to focus on their interests or relax. You can also mention that the right number of subjects may depend on the age of the students and the education system. Giving examples from your own experience or people you know can make your answer more convincing.
