Final answer:
Whispering as it went is not an independent clause, it is a dependent clause that needs to be combined with an independent clause to form a complete sentence.
Step-by-step explanation:
The phrase "whispering as it went" is not an independent clause. An independent clause contains a subject and a verb and can stand alone as a sentence. Without additional context, this phrase appears to lack a clear subject and does not express a complete thought. Therefore, it cannot stand on its own and is likely part of a larger sentence, possibly serving as a subordinate element describing how something happened or the manner of an action.
