<p>A college that allows students to graduate [when not having] obtained an education has not fulfilled its obligation to those students.</p>
<p>Can somebody explain why "when not having" is wrong?</p>
<p>I would guess it is because the [when not having] does not clearly display who it is that must obtain the education: the college or the students? However, I would need to se the other answer choices to tell you which is right. Standardised testing for you. </p>

<p>According to the test answer key, (A) is the answer.</p>
<p>A is the answer, because you would say “without having,” not “when not having.” As I have said (and will probably say) in every post on CR, the key to success is reading a lot of English prose.</p>
