Which common tools are used in mail sorting?

The correct answer is centered on the tools specifically designed for the task of sorting mail efficiently. Automated sorting machines, conveyors, and manual sorting trays are all integral components of the mail sorting process in postal facilities. Automated sorting machines are capable of quickly processing large volumes of mail by reading addresses and determining the correct sorting path, which significantly speeds up the sorting process. Conveyors facilitate the movement of mail from one area to another, thereby allowing for a smooth flow through various sorting phases without manual handling. Manual sorting trays are used by postal workers for further refining the process, allowing for organized storage of mail until it can be distributed.

In contrast, while handheld scanners and delivery trucks are essential in the overall mail delivery process, they are not specifically used for the sorting of mail. Telephones and Internet services play a role in communication but do not contribute directly to the physical sorting of mail. Similarly, pallets and cardboard boxes are more about transportation and storage rather than the sorting process itself. Thus, the components in the correct answer are uniquely suited to the task of sorting mail within postal operations.
