• Provide a concise, domain-grounded correction.

# Example Rubric (Math Reasoning)
- Valid setup of the problem (2 pts)
- Method selection justified (2 pts)
- Step-by-step derivation with no gaps (4 pts)
- Final result with units and sanity check (2 pts)
- Reflection: alternative method or limitations (2 pts)

2) Quick Python inspection for dataset sanity

import pandas as pd

# Load dataset
df = pd.read_csv("domain_samples.csv")

# Basic quality checks
assert df.notnull().all().all(), "Null values detected"

# Detect potential leakage
cols = [c for c in df.columns if "answer" in c.lower()]
print("Potential leakage columns:", cols)

# Stratify by difficulty for balanced evaluation
bins = pd.qcut(df["difficulty"], q=4, labels=["E","M","H","VH"])
print(bins.value_counts())
