Final answer:
A briefcase may cannot be used as an outer wrapper because it cannot be addressed in the same way that a package can. This claim is true.
Step-by-step explanation:
The claim that a briefcase may not be used as an outer wrapper because it cannot be addressed in the same way that a package can is true. A briefcase is typically used to carry and transport items, but it is not designed or labeled in a way that allows for proper addressing like packages or envelopes. Packages typically have addresses written or printed on them, making them suitable for mailing or shipping purposes.
