<p>28) Between the Sales manager and I existed an easy, cooperative working relationship; neither of us hesitated to discuss problems.</p>
<p>Where is the error?
A) And I
B) existed
C) an easy
D) neither of us
E) No error</p>
<p>Could please clearly describe to me why the Answer is A aside from: "The error in this sentence occurs at (A), where an incorrect pronoun case is used. The nominative case of the first-person pronoun I is used where the objective case me is needed."</p>
<p>*Between *is a preposition. Prepositions take objects. Something must exist *between *two other things: between the couch and the wall, or between the dining hall and the library, or between noon and 2:00 p.m.</p>
<p>In this case the thing (the working relationship) exists between the manager and the speaker. And the speaker is referring to himself using a personal pronoun: I.</p>
<p>Except, that’s the wrong form of the pronoun for this sentence. When pronouns are used as subjects (or predicate nominatives), they’re used in the “nominative” case: he, she, we, they, I. When pronouns are used as some kind of object (direct object, indirect object or object of a preposition), they’re used in the objective case: him, her, us, them, me.</p>
<p>So “between the manager and I” is incorrect; “between the manager and me” is correct.</p>
