writing question

<p>hi i got a question.
Because his experience in the naval academy had been rewarding, Bob applied to medical school after he was discharged. No error.
the correct answer is e but i chose d. i thought that a correct sentence would be ...after he had been... since he was discharged and then applied to med school. could someone shed some light on this problem? thx in advance</p>

<p>I believe both would work. However, the sentence above is grammatically correct, so the answer is E.</p>

<p>E. /<em>dkfjdalfjdsklfdajfl;sjfa;</em>/</p>
