Were you impressed by the Doolittle Raid and why?

 Absolutely. The U.S Moral was extremely low after Pearl Harbor. We did not have any Heavy bombers that could make it to Japan. Only small single engine planes could take off from Aircraft carriers (So we thought). The North American B-25 Mitchell was a 2 engine Medium Bomber that theoretically could take off from an aircraft carrier and could make it to Tokyo. So they did it. The only problem was that it could not land back on one because of various reasons. (Tail Wheel, Weight). So they had to send the bombers to Allied China after the raid. The raid was lead by Jimmy Doolittle. And they had to begin the raid early because the convoy carrying the carriers had been spotted and they had to leave before the precious aircraft carriers were attacked. Because the raid began early the planes did not have enough fuel to make it to china and most of them had to ditch into Japanese occupied territory after hitting Tokyo. Every Person who flew in that raid has the Mentality  that they would most likely be captured and executed or be shot down and die. But they wanted to revenge for Pearl Harbor.

option d is correct. corroborated sources of historical evidence   is necessary to validate a claim about an event in history.

historians tend to use written sources, but audio and visual materials as well as artifacts are important objects that supply information to modern historians.

historical sources are usually divided into two categories: primary and secondary sources. depending on the historian's intent, some sources shift their designation. determining what type of sources toimplement, and the level of credibility and reliability of those sources, is a significant step in critical thinking for the historian.
