<p>The first Asian American (to be elected) governor in the United States, George Ariyoshi of Hawaii (has served) longer (than any) of his predecessors when he retired (from) office in 1986. (no error)</p>
<p>I was pretty caught up between B and C. B should be had served, because George is already retired and finished serving his term. </p>
<p>However isn’t C also wrong, since it should be “than did any”, since it’s a faulty comparison between George’s serving and his predecessors?</p>
