D. They directly resulted in the development and use of atomic bombs during the Cold War.

Explanation: The study materials state that the two World Wars 'caused death and destruction on a scale never seen before, leading to the loss of tens of millions of lives.' It also notes that 'After two world wars, organizations like the United Nations were formed to help countries solve problems through talking rather than fighting.' The Great Depression is listed separately under economic crises, and while nuclear weapons were developed, the text doesn't attribute their direct development 'during the Cold War' as a sole impact of the World Wars but rather as a separate negative change.

A. Ano

B. Ne

Explanation: The study materials state that Germany developed long-range rockets like the V-2 during World War II, not World War I.

B. Ne

Explanation: Radar was a technology developed during World War II, using radio waves to detect enemy planes or ships before they arrived. Tanks were invented by the British in World War I to help break the stalemate of trench warfare.

It was used at the very end of the war and changed the world forever because of its massive power.' The other options describe airplanes (scouting), poison gas, and tanks, respectively, not the atomic bomb.
