Which of the following items cannot be sent using USPS Media Mail?

The correct response to this question rests on the specific regulations that govern what can and cannot be sent via USPS Media Mail. Media Mail is a specialized mailing service offered by USPS, primarily intended for sending educational materials and media items, but it does have restrictions.

Video games are categorized differently compared to other media formats like books, educational materials, and manuscripts. While books, papers, and educational materials are explicitly permitted under Media Mail guidelines, video games typically do not fall under the definition of educational media. This exclusivity relates to the intended use of the content; Media Mail is for items that are meant for educational purposes or contain educational content rather than entertainment.

In contrast, books and educational materials are explicitly listed as acceptable for Media Mail shipments, as they serve a clear educational purpose. Papers and manuscripts also fit within the acceptable categories because they can be considered materials that support learning or education.

Therefore, the inability to send video games through USPS Media Mail aligns with the established guidelines focusing on the educational nature of materials that can be sent using this service.
