The correct answer to this open question is the following.
Although there are no options provided, we can say that the statement best describes the connection the author draws between the efforts of the "Greatest Generation" and the American contribution to the war effort is the following: the "Greatest Generation" helped the US supply the Allied Forces with 2.5 million tanks, trucks, and jeeps, which were most instrumental in their success against Germany.
This data refers to the four years the United States participated in World War II. The Greatest Generation that worked in the industries helped to produce 324,000 airplanes that were used at the war front, built more than 6,000 ships that were present in the Atlantic Ocean and other seas during the armed conflict, as well as almost 2,7 million pieces of weaponry and thousands of pieces of artillery.
This great production of weapons, tanks, ships, and planes played a key role in the supply of war materials to the European Allies like the United Kingdom, France, the US, and the Soviet Union. Without this impressive number of war supplies, the Allies would have found it very difficult to win the war.
