Final answer:
The correct answer is option 2. President Eisenhower brought the idea of quick evacuation and interstate highways from Germany to the U.S., aiming to serve both defense and economic growth objectives, leading to the development of the Interstate Highway System.
Step-by-step explanation:
The idea that President Eisenhower brought from Germany to the United States for military purposes was the idea of quick evacuation, which was later implemented through the creation of the interstate highway system. Inspired by the German autobahn network, which he observed during his military service in World War II, Eisenhower believed that a similar system in the U.S. could serve both defense purposes, such as moving troops and evacuating cities in case of a nuclear attack, and also promote economic growth.
This concept was realized with the passage of the Federal Aid Highway Act of 1956, which authorized the construction of the Interstate Highway System, transforming American infrastructure and society.
