Task 12: List the item ID, description, and category for each pair of items that are in the same category. (For example, one such pair would be item FS42 and item PF19, because the category for both items is FSH.) Order the output by category. Task 21: For each sales rep, list the ID, first name, and last name for the customer, along with the sales rep first name, and sales rep last name. All reps should be included in the results. Order the results by rep ID.
