Based on the evidence gathered during the investigation, here is the best partial answer regarding the dataset's size and time period: ### Rows and Columns * **Rows:** The dataset contains exactly **144 rows** within a single table named `championsdataset` (as shown in the Dataset Overview). * **Columns:** The exact total number of columns is **uncertain** because a full schema was not retrieved. However, the data confirms the existence of at least three specific columns: `Begin_reign`, `End_reign`, and `Days`. ### Time Period * **Supported by data:** The dataset tracks historical professional boxing championship reigns. The sampled records show reign start dates (`Begin_reign`) ranging from at least **September 7, 1892** to **July 2, 1921**. * **Uncertainty:** Because the tool output only displays a partial sample of the 144 rows, it is uncertain if the full dataset contains dates earlier than 1892 or later than 1921.
