The content of the file `task.json` begins with metadata about the task, describing it as a set of Kannada riddles with multiple-choice answers. To identify issues related to incorrect answers as per the hint given, I'll need to carefully inspect the dataset's structure, especially the sections containing the questions and their corresponding answers. I will parse this JSON content to examine the questions and their correctness in detail. Let's proceed by evaluating the JSON structure to pinpoint any discrepancies in the provided answers.The keys indicate that the questions might be stored under the `"examples"` key. This is typically where datasets store individual instances such as questions, prompts, or data entries. To address the hint which mentions issues with the lack of correct answers at specific lines, I'll now examine the content under this `"examples"` key, focusing on finding any question-answer pair that might have incorrectness or ambiguity in the provided answers. Let’s proceed to inspect the examples.The structure of each example consists of an `"input"` key representing the riddle and a `"target_scores"` dictionary where each key-value pair identifies a possible answer to the riddle and its correctness score (1 for correct and 0 for incorrect answers). 

Given the hint that some questions in 'task.json' lack correct answers at specific lines, the next step is to programmatically inspect each example to verify if there are any issues related to incorrect answers or the lack of correct answers. Let's conduct a thorough review of each example.We have identified several issues related to the incorrect configuration of answers within the dataset. These issues are characterized by the absence of correct answers (e.g., a total score of 0 for the answer options when exactly 1 answer should be correct). Below are some identified issues formatted according to the provided example:

1.
- **issue**: Incorrect answer configuration at example 5
- **evidence**: A JSON string representing the question-answer set where all options are marked with a score of 0.
- **description**: The total score for this example is 0. Expected: 1 correct answer.

2.
- **issue**: Incorrect answer configuration at example 22
- **evidence**: A JSON string representing the question-answer set where all options are marked with a score of 0.
- **description**: The total score for this example is 0. Expected: 1 correct answer.

3.
- **issue**: Incorrect answer configuration at example 129
- **evidence**: A JSON string representing the question-answer set where all options are marked with a score of 0.
- **description**: The total score for this example is 0. Expected: 1 correct answer.

...

These discrepancies show that there are examples within the dataset where no correct answer is specified, which contradicts the expectation set by the hint that each question should have exactly one correct answer. The dataset curator should revisit these examples to correct the scoring, ensuring each question has a single answer marked as correct.
