I think "I" should be replaced with me. Because if you're going to remove Mary in the sentence, it will be "He wanted ME to do the work" not "He wanted I to do the work" so changing I to me will make more sense.
The misused pronoun is "I" and it should be replaced by "me"
Explanation:
There are different typs of pronouns:
<u>Subject pronouns</u> are the ones that replace subjects and are the doers of an action.
<u>Object pronouns </u>are the ones that replace objects and are the receivers of an action.
In the example provided, the subject pronoun "I" is not replacing a subject so it is incorrect. The correct one is the object pronoun "me" as it is receiver of the action.
Respect for diversity means to have understanding of others differences, and active listening means to hear and comprehend whats being spoken to you. <span />
