Answer 1

The raw materials that the United States produced more of during World War II than any other country were "steel" and "iron"--due largely to the US's relatively large size and the fact that it was protected by two major oceans.

Answer 2

The raw materials that the United States produced more of during World War II than any other country were oil and steel.

During the World War II, oil and steel constituted bare necessities for the nation.

The major suppliers of oil along with the United States were Russia, Mexico, Irak, Persia, Rumania, and Austria.

Countries in conflict needed oil and steel to wage war.
