Hello. You did not enter the text to which this question refers, however, after searching for it on the internet, I was able to find another question exactly the same as yours that presented the text "NOAA’s Big Miracle Worker" as the text in question. If this is your case I hope the answer below can help you.
Answer and Explanation:
The text is an interview with Dave Withrow about the operation that allowed the rescue of three gray whales that were trapped in Barrow, Alaska in 1988. Withrow shows that he was the qualified professional to work in this operation because he had experience working with marine manifers, such as whales, because when he worked at NOAA at the Alaska Fisheries Science Center, his department was responsible for taking care of any matter related to whales. This can be seen in the first paragraph of the text, in the lines: “... anything whale-related, especially on the West Coast, comes through our office.”
For the first question, item D is correct because you'll need to place a comma before and after parenthetical elements: "<span>The beach, which closes after Labor Day, has white sand."
For the second question, item D is correct because commas are only needed for a series of three or more elements; thus, no commas are needed: "</span><span>I bought a beautiful pitcher and eight glasses."
For the third question, there are no commas needed; thus, item A is the correct sentence: "</span><span>The music made me sleepy."
</span><span>
For the fourth question, item C is the correct response because commas are needed after subordinate clauses that begin a sentence: "</span><span>As the band marched across the field, the crowd cheered."
</span>
For the fifth question, item D is the correct response because in order to keep from having a run-on sentence a comma is always needed before a conjunction that is connecting two complete sentences: "<span>He works long hours, yet he keeps up with his studies."</span>
