Final answer:
To sort a table by insurance agent, description, and duration, use spreadsheet sorting features with sequential sort levels and a custom sort order for the descriptions: Natural Disaster, Flood, Fire, Theft, Accident.
Step-by-step explanation:
To sort a table by an insurance agent in alphabetical order, add a second level to sort by description, and then create a custom sort order for the descriptions as follows: Natural Disaster, Flood, Fire, Theft, Accident, and finally, add a third level to sort by duration from smallest to largest, you will typically use the sorting features of a spreadsheet program like Microsoft Excel or Sheets. Here's a step-by-step guide:
Select the range of cells in your table that you want to sort.
Go to the Data tab and click on 'Sort'.
In the Sort dialog box, choose 'Insurance Agent' from the Sort by drop-down menu to sort alphabetically.
Click on 'Add Level' to add a second level of sorting.
Choose 'Description' for the second level and select 'Custom List' to order the descriptions according to the custom order provided.
Enter the custom order: Natural Disaster, Flood, Fire, Theft, Accident.
Click on 'Add Level' again to add a third level of sorting for duration.
Choose 'Duration' and sort from smallest to largest.
Click 'OK' to apply the sort to your table.
By following these steps, your table will be sorted first by insurance agent alphabetically, then by the custom sort order of descriptions, and finally by duration from shortest to longest.
