Answer:
B. It answers the question when and modifies the verb put.
Explanation:
<u>The given sentence - When you get home from the game, put your dirty clothes in the hamper - a complex sentence.</u>
A complex sentence contains an independent clause and at least one dependent clause. An independent clause can stand alone as a sentence as it has a complete thought, we can understand what is going on and we get the full information on a subject. A dependent clause cannot stand alone as it doesn't have a complete thought, even though it can have a subject and a verb.
In our case:
<em>The independent clause - </em><u><em>put your dirty clothes in the hamper.</em></u>
<em>The dependent clause - </em><u><em>When you get home from the game.</em></u>
Our dependent clause is adverbial. These are some of the common purposes of adverbial causes and common subordinating conjunctions:
<em>Condition:</em><em> if, unless</em>
<em>Reason:</em><em> because, since, as</em>
<em>Time:</em><em> before, after, while, as soon as, </em><em>when,</em><em> since, until</em>
<em>Purpose:</em><em> in order to, so that</em>
<em>Concession: </em><em>although, though, even though, while, whereas</em>
So we see our dependent clause is an adverbial clause of time as it has a conjunction of time, and is attached to the main clause with the subordinating conjunction<u> 'when'.</u> It explains the verb put, it shows exactly in what time the doer should put the clothes in the hamper.
