Focusing on a specific point in the IELTS Writing Task 2 is acceptable as long as your answer addresses the prompt fully. If your response emphasizes that excluding genders from certain work is unsuitable due to the free market economy, it can still be relevant. However, ensure you cover the prompt broadly enough to avoid missing key aspects and to demonstrate a comprehensive understanding. This approach should not lead to failing the task as long as your argument is clear, relevant, and well-supported.
