How did american make money fron the war in europe

Explanation:

Although the United States was actively involved in World War I for only nineteen months, from April 1917 to November 1918, the mobilization of the economy was extraordinary. (See the chronology at the end for key dates). Over four million Americans served in the armed forces, and the U.S. economy turned out a vast supply of raw materials and munitions. The war in Europe, of course, began long before the United States entered. On June 28, 1914 in Sarajevo Gavrilo Princip, a young Serbian revolutionary, shot and killed Austrian Archduke Franz Ferdinand and his wife Sophie. A few months later the great powers of Europe were at war.

Many Europeans entered the war thinking that victory would come easily. Few had the understanding shown by a 26 year-old conservative Member of Parliament, Winston Churchill, in 1901. “I have frequently been astonished to hear with what composure and how glibly Members, and even Ministers, talk of a European War.” He went on to point out that in the past European wars had been fought by small professional armies, but in the future huge populations would be involved, and he predicted that a European war would end “in the ruin of the vanquished and the scarcely less fatal commercial dislocation and exhaustion of the conquerors.”[1]

answer; i believe the above statement is (true);

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.
