Question

A part of the sentence is underlined. Below are the alternatives which may improve the sentence. Choose the correct alternative. The machines stopped to work an hour ago.

• A. stop working
• B. stopped working
• C. stops work
• D. stopped the work

Hint:

When referring to past events, use the past tense form of the verb, in this case, "stopped working." The verb "stop" is followed by the gerund ("working") to indicate cessation of an activity.

Answer 1

The Correct Option is B

The correct choice is "stopped working" because we are referring to an action that has already occurred in the past. The phrase "stopped working" correctly indicates that the machines ceased their function at a specific time in the past. "Stop working" is in the present tense, and the other options either change the meaning or are grammatically incorrect.
