Answer:
The River Jordan, <u>which empties into the Dead Sea</u>, flows through the Rift Valley.
Explanation:
An adjective clause is a clause that contains a subject and a verb while also acting as an adjective for the noun in the sentence. It usually begins with the words like "who, which, whom, that, when, where" etc. giving information about the noun or pronouns in the sentence.
In the given sentence, the River Jordan is the noun. And the clause <em>"which empties into the Dead Sea"</em> is the adjective clause that combines the two sentences into a single sentence and also modify or describe the noun. So, the second sentence is the correct structure of the original sentence.
Thus, the correct answer is-
<em>The River Jordan, </em><u><em>which empties into the Dead Sea</em></u><em>, flows through the Rift Valley.</em>
