Based on the hint provided and after reviewing the content of the README and the CSV file, I've identified the following issues according to the specified format:

1. **Issue**: Variables in CSV file lacking clear definitions in README
   **Evidence**: The README file does not provide definitions or descriptions for the variables found in the CSV file, such as `QUOTE_DATE`, `COVER_START`, `CLAIM3YEARS`, `P1_EMP_STATUS`, `P1_PT_EMP_STATUS`, `BUS_USE`, etc.
   **Description**: The README document should include a section that describes each variable found in the CSV dataset, explaining its meaning, type, any coding used (e.g., what `N`, `Y`, `R`, `E` represent in various columns), and the importance of these variables within the context of home insurance data. This omission makes it difficult for users of the dataset to understand the data without guessing or making assumptions about what each column represents.

2. **Issue**: README lacks explanation of dataset structure
   **Evidence**: Despite mentioning that the dataset includes "police's years between 2007 and 2012" and contains "some significants characteristics of polices, building's characteristics, the zone, the privileges, the faults, some risk indicators and so on," the README does not specifically map these descriptions to actual variables in the CSV file.
   **Description**: For clarity and ease of use, it would help users if the README contained a clear mapping or table that links the general descriptions provided to the actual names of variables in the dataset. Without this linkage, users may struggle to identify which columns correspond to "building's characteristics," "the zone," or "some risk indicators," among other described attributes.
