C). The sentence contains a dependent clause followed by an independent clause.
Explanation:
A dependent or subordinate clause is demonstrated as the clause that usually begins with a subordinating conjunction and involves a subject along with a verb but doesn't convey a complete thought and function as an adjective, adverb, or noun phrase. While an independent clause is complete in itself and functions to accomplish the meaning of the subordinate clause.
In the given sentence, the answer choice that best describes the combination of two clauses in sentence(16) is that it contains a dependent clause 'When you come across a difficult passage' beginning with the subordinating conjunction 'when' and this subordinate clause is followed by the independent clause 'analyzing the sentence structure can often help you to figure out the meaning of difficult sentences' that completes the meaning of the sentence. Thus, <u>option C</u> is the correct answer.
