Question

1. choose the sentence that does not contain correct apostrophe mechanics. the students’ lockers were organized neatly. the managers office was locked after the meeting. the scientist’s discovery changed the course of history. the musicians’ instruments were tuned before the concert.

Explanation:

The possessive form of "managers" should be "managers'" to show that the office belongs to the managers. In the sentence "The managers office was locked after the meeting", there is no apostrophe to indicate possession, which is incorrect. The other sentences use apostrophes correctly for plural possessives ("students'", "musicians'") and singular possessives ("scientist's").

Answer:

The managers office was locked after the meeting.
