What postal service includes parcel post, bonded printed matter, and library mail?

The correct answer is Package Services because this category encompasses a variety of mailing options specifically designed for different types of packages. Package Services includes parcel post (which allows for the mailing of packages at a lower cost), bonded printed matter (for certain educational materials), and library mail (which is specifically for mailing library materials at reduced rates). These services are tailored to offer flexibility for shipping specific types of items, making them more affordable and appropriate for the needs of senders who are shipping bulk or specialized materials.

Understanding the distinction between Package Services and other mailing options is essential. For example, Standard Mail typically covers bulk advertising and promotional mail rather than the specialized services found within Package Services. Priority Mail is focused on fast shipping and includes benefits like tracking and insurance, which are not the primary features of Package Services. Media Mail, although related to specially discounted rates for educational materials and media, does not encompass all the elements included under Package Services, particularly parcel post and bonded printed matter. Thus, Package Services is the best choice as it includes all listed options within its scope.
