Answer:
Passage 1 and 2 - Flashback.
Passage 3- Flash forward.
Explanation:
Flashback is the going back to the time in the past which was set before the present scene. Flashbacks provide the extra crucial information from the past to the current situation. They are a character's thinking or reminiscing of the times gone by. Passages 12 and 2 deal with the characters thinking back tro the times they had experienced or done. So, flashback will be matched with passage 1 and 2.
Flash-forward is the exact opposite of flashback. It represents the occurrence or presentation of scenes yet to come or expected to happen in the coming future scenes. Passage 3 reveals/ deals with what is to happen or to be expected in the future ("<em>Let me behold what I shall be in the days to come</em>") . This will be paired with passage 3.
It would be answer "a"- because if you are not putting the commas in, it would be just a run-on sentence. So, it would be, "World War II, which lasted from 1939 to 1945, was a global conflict involving nearly every nation in the world." Having the commas in will help the reader digest and sink the information in on what the topic is, without the sentence just running through without any commas. Hope this helps. =)
B with the sentence: <span> Either Mom or Dad cook dinner for the family each night.</span>
