The two excerpts that best identify the main ideas of the article are the excerpts presented in options C and D, as they show how the American industry had a great relevance during the Second World War.

We can get the answer because:

The article shows how the American industry, besides being crucial for the victory of the allies, was essential for the American economy.
The US entry into the war created the need to establish an assembly system that would optimize industrial production, allowing the US Army to have sufficient equipment and ammunition for the battles.
This also allowed the US government to lend and sell equipment to other allies, which generated a large profit for the US.

With that, we can affirm that the article highlights the importance of the American industry not only for the war, but also for the economy.
