Answer:
T.J.'s relationships show the difference between true friendship and false friendship.
A) (Sentence 2) The freighter Florentine, 320 miles northeast of the Hawaiian Island of Hilo was lumbering along at about 15 knots when a garbled message came in over the radio.
This is the sentence that has a missing necessary comma. Another comma should have been placed after the word Hilo and before was.
The commas in this sentence enclosed nonessential information.
<span>The freighter Florentine, 320 miles northeast of the Hawaiian Island of Hilo, was lumbering along at about 15 knots when a garbled message came in over the radio.
</span>
Nonessential information means that if the said phrase is deleted from the sentence, then the sentence would still convey the same message.
<span>
The freighter Florentine was lumbering along at about 15 knots when a garbled message came in over the radio.</span>
