Question 23

The word "envelope's" is used incorrectly.

In the provided sentence, the word "envelope's" is incorrectly formed as it implies possession, suggesting something belonging to an envelope, rather than referring to multiple envelopes. The correct term should be "envelopes" to denote more than one envelope without indicating ownership.

A) block

The term "block" is used correctly in this context, referring to a section of a street or neighborhood. It appropriately identifies the area where the mail carrier performs their job of delivering mail.

B) mail carrier's

The phrase "mail carrier's" is also correct as it indicates possession, referring to the job of the mail carrier. The use of the apostrophe here is appropriate as it denotes that the job belongs to the mail carrier.

C) envelope's

The word "envelope's" is used incorrectly because it suggests possession, which is not suitable in this context. The sentence is intended to refer to multiple envelopes rather than something belonging to an envelope, thus it should be "envelopes."

D) every

The word "every" is correctly used in this sentence to indicate that the mail carrier is responsible for all mailboxes on the block. It emphasizes the inclusivity of the delivery process.

Conclusion

The use of "envelope's" is incorrect as it implies possession rather than plurality, which is required in this context. All other options are used correctly within the sentence, either describing locations or roles without misapplication of grammatical rules. The core concept being tested is the correct use of apostrophes, and "envelope's" fails to meet that standard.
