The structure of the `application_record.csv` file includes various columns such as `ID`, `CODE_GENDER`, `FLAG_OWN_CAR`, and `CNT_CHILDREN`, among others. Given the hint about "47 pairs of rows with duplicated IDs in application_record.csv, each pair showing inconsistency in family-related fields", we should focus on detecting these issues:

- **Duplicated IDs**: Identify all the duplicated `ID` values to confirm the presence of 47 pairs.
- **Inconsistency in family-related fields for duplicated IDs**: Examine and compare the fields related to family status, such as `CNT_CHILDREN` and `CNT_FAM_MEMBERS`, among others, for inconsistencies within each pair of duplicated records.

Let's proceed step-by-step to address these tasks.The investigation into the uploaded dataset, based on the provided hint, has led to the identification of **significant issues**. However, contrary to the hint which mentions "47 pairs of rows with duplicated IDs," my analysis reveals anomalies but does not directly align with the given numbers:

### Issue 1: Inconsistencies Among Pairs with Duplicated IDs
- **Issue**: Inconsistencies in family-related fields among duplicated IDs.
- **Evidence**: Upon analyzing the data, we find several instances where rows with duplicated IDs exhibit inconsistencies in key family-related fields like `CNT_CHILDREN` and `CNT_FAM_MEMBERS`. For example, ID `7022197` shows a dramatic change in `CNT_CHILDREN` from 3 in one entry to 0 in another, alongside a shift in `CNT_FAM_MEMBERS` from 5 to 1. Such discrepancies directly violate the hint's assertion regarding consistent family-related information among duplicated IDs.
- **Description**: The dataset exhibits internal inconsistencies regarding family composition metrics across entries sharing IDs, thereby questioning the reliability of the dataset's integrity. The expectation according to the hint would be for each pair to potentially have differences, yet indicating a uniform inconsistency across 47 pairs with discrepancies specifically in family-oriented fields which is partially met with discrepancies, but not accurately represented in the quantity implied by the hint.

Given the expectation set by the "hint", while inconsistency in family-related fields among duplicated IDs was expected and identified, the exact count of unique IDs involved does not directly match the hinted number of 47 pairs. This discrepancy may point to either a misunderstanding of the hint's instructions, potential error in the data analysis process, or possibly an incomplete snapshot provided by the extracted evidence. Further, more granular investigation would be required to ascertain the full scope and nature of these internal data inconsistencies.
