How did advancements in technology differentiate World War 2 from World War 1? A. The development of long-range weapons reduced the number of overall casualties. B. Powerful tanks and aerial bombings made trench warfare obsolete C. The introduction of chemical weapons changed the nature of combat. D. The use of large battleships to transport to deploy troops on land replaced aerial attacks

The correct answer is B. Powerful tanks and aerial bombings made trench warfare obsolete.

Advancements in technology during World War II significantly transformed the nature of warfare compared to World War I:

1. Powerful Tanks: The development of highly mobile and powerful tanks, along with mechanized infantry, led to the evolution of armored warfare. Tanks were used in large numbers and played a pivotal role in maneuver warfare, rendering the static trench warfare of World War I ineffective.
2. Aerial Bombings: Aerial bombings by both bombers and fighter aircraft became a major tactic in World War II. Bombing raids targeted cities, infrastructure and military installations, impacting both military and civilian populations.
3. Naval Warfare and Aircraft Carriers: While battleships were still in use, aircraft carriers became a primary component of naval warfare. They allowed for long-range aerial attacks and changed naval strategies significantly.
4. Improved Communication and Radar Technology: Technological advancements in communication and radar systems improved command and control of military forces, enabling better coordination and strategic planning.

Chemical weapons were used in World War I, but their use was limited and regulated by international agreements in World War II. The major technological differences in World War II, as stated in option B, lay in the effectiveness of tanks, aerial bombings, and the shift away from static trench warfare towards more mobile and mechanized forms of combat.
