<p>The first one is the correct one. I got it right, but only by process of elimination. so I want to know:
are modifiers always dependent clauses? They can't be independent clauses?</p>
<p>The correct answer choice doesn’t have a dependent clause. </p>
<p>- Dependent clauses function adverbially; that is, they modify the verb of the independent clause to which they are attached. For example:</p>
<p>“Because I was hungry, I ate my leg.” </p>
<p>The depedent clause modifies “ate” in its offering of a reason for the eating.</p>
<p>- Participial phrases function adjectively; that is, they modify a noun (usually, the subject of the independent clause to which they are attached). For example:</p>
<p>“Starving, I grabbed a ‘lite’ yogurt.”</p>
<p>The participle “starving” modifies “I.”</p>
<p>“Its fossil record virtually unchanged over 100 million years” is a participial phrase.</p>
