<p>On the error ID's, i got one sentence stated below:</p>
<p>(One of) the children on the playground (is eating) ice cream, (while) the others (are) enjoying the see-saw. (No Error)</p>
<p>The answer was E, no error.
However, isn't this sentence a run-on because you can't connect an independent and dependent clause with a comma....
Does collegeboard even test comma splicing and sentence fragments?</p>
<p>Also, heres just a werid thing i was wondering about..</p>
<p>when do you use thereby, whereby and others of the sort?</p>
<p>You definitely can connect an independent and dependent clause with a comma - how else would you connect them? "While" is used as a subordinating conjunction.</p>
<p>no you can't, when putting an independent and dependent clause together, you are not supposed to use a comma
you would just leave it as it is but without the comma</p>
<p>But even if the sentence was incorrect in that the comma should be removed, choosing (while) would not have fixed it, since it didn't include the comma...</p>
<p>Here's the rule according to the Purdue OWL:</p>
<p>"However, don't put a comma after the main clause when a dependent (subordinate) clause follows it (except for cases of extreme contrast).</p>
<pre><code>1. She was late for class, because her alarm clock was broken. (incorrect)
2. The cat scratched at the door, while I was eating. (incorrect)
3. She was still quite upset, although she had won the Oscar. (correct: extreme contrast)
</code></pre>
<p>"</p>
<p>...hmmm. Where is this particular question from?</p>
<p>I'm currently not sure which way is correct, but if I were to give an argument supporting the use of the comma, it would be this (though the internet seems to disagree with it):</p>
<p>The word "while" in gxing's sentence does not have the same meaning as the word "while" in the SAT sentence. In gxing's sentence, "while" means "during the time that...". In the SAT sentence, the "while" means "but"...therefore it acts as a coordinating conjunction, separating two independent clauses.</p>
