Step-by-step explanation:
The Civilian Part of a Country at War and a Video Game
The civilian part of a country at war refers to the segments of society not actively engaged in military combat but still affected by the war, such as their involvement in production, morale, and governance. For European countries during World War II, the line between the home front and the battlefield was oftentimes blurred, as civilians found themselves in close proximity to combat and even resistance activities. The term 'home front' was critical during wars as it symbolized the efforts of those not in uniform, including the altering of daily life, increased production, and strong societal impacts. Indeed, the home front in the U.S. during World War II involved 10% of the population serving in the armed forces, with civilians rallying behind the war effort in numerous capacities.
As for the 2011 video game where the U.S. is occupied by North Korea, the answer is a) Homefront. This game depicts a fictional scenario where the civilian population experiences the dire consequences of an occupying force, drawing parallels to the historical concept of the home front.
