Based on the content of the dataset file and the hint provided about incorrect answers marked in dataset examples, I have identified the following potential issues:

1. **Duplicate Question with Different Correct Answers:**

- **Issue**: The dataset contains duplicate questions with different answers marked as correct.
- **Evidence**:

```
{
  "input": "A 25.0 kg crate it lifted on to a 2.0 m ledge by a worker that exerts 325 W of power. How long does it take to reach the ledge?", 
  "target_scores": {
    "P = dE / dt": 1,
    ...
  }
},
{
  "input": "A 25.0 kg crate it lifted on to a 2.0 m ledge by a worker that exerts 325 W of power. How long does it take to reach the ledge?", 
  "target_scores": {
    "U = m * g * h": 1,
    ...
  }
},
```

- **Description**: In this example, the same question is provided twice but with different correct answers in the '`target_scores`' field. This inconsistency could potentially lead to confusions since each example in the dataset is expected to have a unique correct answer. Such duplications with different answers marked as correct might indicate an error in the answer marking or a misunderstanding of the question’s context.

2. **Contradictory Information Across Examples:**

- **Issue**: Different physics formulas marked as correct for the same physical scenario.
- **Evidence**:

```
{
  "input": "A 0.390 kg hockey puck is accelerated across a frictionless sheet of ice from rest to a speed of 15.0 m/s in 1.5 m. How much power is exerted on the puck?", 
  "target_scores": {
    "P = dE / dt": 1, 
    ...
  }
},
{
  "input": "A 0.390 kg hockey puck is accelerated across a frictionless sheet of ice from rest to a speed of 15.0 m/s in 1.5 m. How much power is exerted on the puck?",
  "target_scores": {
    "K = 1/2 * m * v ^ 2": 1,
    ...
  }
},
```

- **Description**: Here, two examples concerning the acceleration of a hockey puck across ice list different physics formulas as the correct answer to essentially the same query. The first example identifies '`P = dE / dt`' as the correct formula for the given scenario, whereas the second establishes '`K = 1/2 * m * v ^ 2`' as correct. This indicates an underlying issue, as both formulas apply to different concepts (power and kinetic energy, respectively), suggesting a mislabeling of correct answers or a misunderstanding of the scenario outlined in the question.

These issues could potentially misguide individuals or models trying to learn from this dataset. It's vital that each question within the dataset has a singular, accurately identified correct answer based on the physics principles that the question seeks to assess.
