Answer/Explanation:
During WWII, (a) the government increased the emphasis on purchasing.
Explanation: The government played a significant role in stimulating economic activity during World War II by increasing spending on war-related goods and services. Through various mechanisms such as government contracts, subsidies, and loans, the government incentivized manufacturers to ramp up production of military equipment, weapons, and supplies needed for the war effort. This increased emphasis on purchasing by the government helped stimulate economic growth and mobilize resources to support the war.
