System: You are a helpful and precise assistant in checking the quality of the answer.
User: We would like to request your feedback on the performance of the response of the assistant to the user instruction displayed below. In the feedback, I want you to rate the quality of the response in these 3 categories according to each scoring rubric:

Factuality: Did the model extract pertinent and accurate background knowledge without any misinformation when factual knowledge retrieval is needed? Is the response supported by reliable evidence or citation of the source of its information?
Score 1: The model did not extract pertinent background knowledge and provided inaccurate or misleading information. There is no support for the response through reliable evidence or source citations.
Score 2: The model extracted some relevant background knowledge but included inaccuracies or incomplete information. The response has minimal support through evidence or citations, with questionable reliability.
Score 3: The model extracted generally accurate and pertinent background knowledge, with minor inaccuracies or omissions. The response is partially supported by evidence or citations, but the support may not be comprehensive or fully reliable.
Score 4: The model extracted mostly accurate and relevant background knowledge but missed minor evidence or citations to support the response.
Score 5: The model extracted complete and accurate background knowledge without any misinformation. The response is fully supported by reliable evidence or citations that are accurate, relevant, and comprehensive in addressing the instruction.
Logical Robustness: Does the model ensure general applicability and avoid logical contradictions in its reasoning steps for an instruction that requires step-by-step logical process? This includes the consideration of edge cases for coding and mathematical problems, and the absence of any counterexamples.
Score 1: The logic of the model's response is completely incoherent.
Score 2: The model's response contains major logical inconsistencies or errors.
Score 3: The model's response contains some logical inconsistencies or errors, but they are not significant.
Score 4: The model's response is logically sound, but it does not consider some edge cases.
Score 5: The model's response is logically flawless and it takes into account all potential edge cases.
Comprehension: Does the response fulfill the requirements of the instruction by providing relevant information especially when the instruction is complex and includes multiple requirements? This includes responding in accordance with the explicit and implicit purpose of given instruction.
Score 1: The response is completely unrelated to the instruction, or the model entirely misunderstands the instruction.
Score 2: Most of the key points in the response are irrelevant to the instruction, and the response misses major requirements of the instruction.
Score 3: Some major points in the response contain irrelevant information or miss some requirements of the instruction.
Score 4: The response is relevant to the instruction but misses minor requirements of the instruction.
Score 5: The response is perfectly relevant to the instruction, and the model fulfills all of the requirements of the instruction.

How can I use SQL to return the last record in each group of a table?

[Ground truth Answer]
To return the last record in each group of a table using SQL, you can use window functions like ROW_NUMBER(), RANK(), or DENSE_RANK() in combination with the PARTITION BY clause. Here is a general example using the ROW_NUMBER() function:

Suppose you have a table named "your_table" and you want to group the records by "group_column" and get the last record based on a column named "order_column".

```sql
WITH ranked_data AS (
  SELECT *,
    ROW_NUMBER() OVER (PARTITION BY group_column ORDER BY order_column DESC) AS row_num
  FROM your_table
)
SELECT *
FROM ranked_data
WHERE row_num = 1;
```

Replace "your_table", "group_column", and "order_column" with the appropriate values for your specific table and requirements.

Here's how the query works:
1. The query first creates a common table expression (CTE) named "ranked_data" that includes all columns from your table along with a new column named "row_num". This new column returns the row number within each group ordered by the "order_column" in descending order.
2. The query then selects all records from the "ranked_data" CTE where "row_num" = 1, which represents the last record in each group based on the sorting of "order_column".

[Assistant's Response]
To return the last record in each group of a table using SQL, you can utilize the `ROW_NUMBER()` window function along with either a Common Table Expression (CTE) or a subquery. Here’s a step-by-step guide on how to do this:

### Using a Common Table Expression (CTE):

```sql
WITH RankedRecords AS (
    SELECT *,
           ROW_NUMBER() OVER (PARTITION BY group_column ORDER BY timestamp_column DESC) AS rn
    FROM your_table
)
SELECT *
FROM RankedRecords
WHERE rn = 1;
```

### Using a Subquery:

```sql
SELECT *
FROM (
    SELECT *,
           ROW_NUMBER() OVER (PARTITION BY group_column ORDER BY timestamp_column DESC) AS rn
    FROM your_table
) AS RankedRecords
WHERE rn = 1;
```

### Explanation:
- **`ROW_NUMBER()`**: This function assigns a unique sequential integer to rows within a partition of a result set, starting at 1 for the first row in each partition.
- **`PARTITION BY group_column`**: This clause divides the result set into partitions based on the specified column (e.g., `group_column`).
- **`ORDER BY timestamp_column DESC`**: This orders the rows in each partition so that the most recent record appears first.
- Finally, you filter the results to get only the rows where `rn = 1`, which corresponds to the last record in each group.

Make sure to replace `your_table`, `group_column`, and `timestamp_column` with the actual names relevant to your database schema. This approach will effectively give you the last record for each group based on the specified ordering.

[The End of Assistant's Response]

Please give feedback on the assistant's responses. Also, provide the assistant with a score on a scale of 1 to 5 for each category, where a higher score indicates better overall performance. Make sure to give feedback or comments for each category first and then write the score for each category. Only write the feedback corresponding to the scoring rubric for each category. The scores of each category should be orthogonal, indicating that 'Efficiency of User Alignment' should not be considered for 'Readability of User Alignment' category, for example. 

Lastly, return a Python dictionary object that has skillset names as keys and the corresponding scores as values.
