The issue encountered is due to a KeyError, which indicates a problem with how the data is being accessed. It appears that the expected key 'data' does not exist at the top level of the JSON structure. I will adjust my approach to correctly navigate the file structure and identify potential issues. Let me correct this and proceed with identifying the specific issues related to the hint provided.The structure of the JSON file includes top-level keys such as 'canary', 'name', 'description', 'keywords', 'metrics', 'preferred_score', and 'examples'. It appears that the actual questions and potential answers are likely contained within the 'examples' key. I will adjust the code to assess the items within the 'examples' key for the specified issue.The encountered TypeError is due to attempting to serialize a `dict_keys` object directly, which is not JSON serializable directly. This occurred while trying to include the answers (extracted as keys of a dictionary) in the evidence data for a found issue. I need to convert these `dict_keys` objects to a list before trying to serialize them. Let me correct this and proceed.I have identified several issues in the uploaded dataset concerning the provided hint about "missing correct answers in questions." Here are the issues identified:

1. **Issue:** Incorrect number of correct answers
   - **Evidence:** A question in Kannada, with four potential answers, but no correct answer specified.
   - **Description:** No correct answer specified. The question should have exactly one correct answer, but none was found.

2. **Issue:** Incorrect number of correct answers (Similar issues were found for multiple questions)
   - **Evidence:** Questions in Kannada, with choices of answers provided but no correct answer specified.
   - **Description:** Each of these instances has the same problem, where there should be exactly one correct answer specified, but none was found. This is a significant issue as the dataset is expected to provide correct answers for the purpose of evaluating responses to these questions.

Due to the large amount of similar issues and the repetitive nature, the response here represents a sample of the types of issues found rather than listing all occurrences, which all relate to the absence of specified correct answers in the dataset.
