The children of the man who works with me ____ broken the window this morning.werehavehadhaswas

To fill in the blank in the sentence "The children of the man who works with me ____ broken the window this morning," we need to choose the correct form of the verb that fits grammatically.

1. Understanding the Sentence Structure: The sentence hints that an action has already occurred before the current moment (the breaking of the window).

2. Analyzing the Options:

   • were: This is a past tense form but doesn't fit since it doesn't indicate a completed action.
   • have: This can fit in the present perfect tense, making sense in the context of an action completed in the past that affects the present.
   • had: This is used in past perfect tense but implies an action completed before another past action, which does not fit well in this context.
   • has: This form is singular and does not agree with "children," which is plural.

3. Choosing the Correct Option:

   • The present perfect tense is indicated here, and since "children" is plural, “have” is the correct choice.

Final Answer

The correct word to fill in the blank is "have." The complete sentence is: "The children of the man who works with me have broken the window this morning."
