Question

which two groups cooperated with the government to switch from peacetime to wartime production?
state governments and armed forces
labor and business
the allies and the axis powers
the president and congress

Explanation:

During the transition from peacetime to wartime production, labor (workers) and business (companies) cooperate with the government. Labor provides the workforce needed for increased production, and businesses adjust their operations to produce war - related goods. State governments and armed forces have different primary functions. The Allies and Axis powers are opposing coalitions in war, not entities that cooperate with a single government for this transition. The president and Congress are parts of the government itself, not external groups in this context.

Answer:

B. labor and business
