In a feudal system, a vassal, akin to a serf in most contexts, in general worked land on a lord's fiefdom in exchange for some of the produce from the land and some military protection.
The media coverage during the Vietnam War gained popularity since more than half of the Americans have television. It became more engaging to see news in front of the audience's eyes than to read the newspapers. The evening news was more of the war than any other tv shows.
The negative effect of it was more people were ready to accept the news presented to them and loose understanding of the facts on their own.
I also struggled with this question and I'm not 100% sure about my answer, but it's better than no answer. I used the little scale thing on the bottom right corner of the map. And I found out that by sea it was around 700 miles. And by land, I got around 350, but I rounded up to 400. Hopefully I was able to help... this stuff can be hard. I hate DBQ packets, but you gotta do your best.
Have a wonderful day and good luck in history :-)
