I have analyzed the "task.json" file and identified a potential issue:

1. **Missing Correct Answers in Questions**: The questions lack specified correct answers. For example:
    - **Evidence**: 
        - "Which animal is known as the 'king of the jungle'?" with answers: "Tiger", "Lion", "Elephant".
        - "Who painted the Mona Lisa?" with answers: "Pablo Picasso", "Leonardo da Vinci", "Vincent van Gogh".
    - **Description**: Correct answers are not included, which is essential for the dataset's completeness and usability.

This is one potential issue. Let me know if you need more issues identified or further assistance.
