<p>My father worked his way through <em>law school attending classes in the day</em> and waiting tables at a restaurant at night.
A) law school attending classes in the day
B) law school; attending classes all day
C) law school, he attended classes in the day
D) law school, attending classes in the day
E) law school, having attended classes in the day</p>
<p>I chose A, the answer's D. Can anyone explain why there needs to be a comma?</p>
<p>So it’s not a run-on trainwreck…=P</p>
<p>I don’t believe the law school attends any classes.</p>
<p>If one or more participial phrases come at the end of a sentence and do not immediately follow the word they modify, they are set off by a comma. The phrases “attending classes…” and 'waiting tables…" are participial phrases modifying ‘father’.</p>
<p>I agree with Wood5440.</p>
<p>That said, I don’t recall a “comma” or “not a comma” writing question on the SAT, or for that matter on many of the second sources of SAT questions.</p>
<p>Thank you Wood5440. That clears things up.</p>
