U,S, Involvement to Win World War II.

Explanation:

Prior to the Japanese surprise attack to the U.S. aeronaval at Pearl Harbor, Hawaii, a large portion of the U.S. population had expressed their desire to keep the country out of the war that had broken out in Europe in September 1939 when Nazi Germany invaded Poland and France and Britain declared war on Germany. At the time, celebrities like Charles Lindbergh, a national hero after achieving the feat of  completing the first flight of a single-seat airplane across the Atlantic, were very vocal about the neutrality of the United States in a war that was perceived as yet another European country. even though Britain had barely survived a Nazi invasion, it was fighting a losing battle as it lacked the manpower and resources to beat the German military. Pearl Harbor, and the ensuing entrance of the U.S. in World War II, would begin to tip the scales on behalf of Britain and the Allies in 1942, as the Axis Powers' expansion was stopped when the Japanese Imperial Navy lost the Battle of Midway against the U.S. Navy in June, the German Afrika Korps lost the Battle of El Alamein to the British Eight Army in October, and the German 6th Army was completely routed by the Soviet Red Army in January 1943. The arrival or ever increasing amount of U.S. troops, supplies, equipment and weapons systems to the battlefronts would prove decisive for the ultimate Allied victory in May 1945 in Europe, and September 1945 in the Pacific.

explanation:

genetics is the study of how dna works, the methodologies defining the new recent technologies allow scientist to have a panoramic view of the entire dna landscape, especially how genomes interact with their environment, including off course, factors outside their organisms.

thus is very possible the existence of both scenarios, where populations of isolated individuals have different genetic traits, and share traits related to genetic mutation, due rats can easily travel overseas using human transport channels. so scientists could get a vast number of data, including human interaction, evolution of rodents, health development, spread of infections, development of new organisms, how genomes evolve in different environments and so on.
