Fix Greater Than

The model receives the prompt (and optional system message). The run uses scorer contains_all with the JSON configuration below. Pass/fail and partial credit are determined entirely by that scorer against the model output; no human grading.

Fix the bug and return corrected Python code only.

def is_adult(age):
    return age > 21

{
  "expected_contains": [
    "def is_adult(age):",
    "age >= 18"
  ]
}
