I need help answering two through four I only have 25 minutes

There is a website called Britannica and there is an article about the Vietnam war and i think you can find the answers there. Sadly I cannot copy anything from there to here because won’t let me and give me a warning notification :/ [[https://www.britannica.com/topic/The-Vietnam-War-and-the-media-2051426]]

1, 4, and 5 are all conflicts

3 is blunder, i’m not sure about the last one but the first two look correct
