The inspection of "train.csv" revealed an issue aligning with the provided hint. Here is an identified issue:

{
    "issue": "Missing 2nd column data in Line 215",
    "evidence": "3530.15736917\n",
    "description": "According to the hint, Line 215 in 'train.csv' is expected to contain multiple columns of data. However, after examining this line, it appears to contain only a singular data entry without any evident separation for a 2nd column. This suggests that the data intended for the 2nd column is missing, which could attribute to issues in data integrity or processing tasks that depend on the completeness of each row."
