The Truman Doctrine was the event that triggered off the Cold War.
Explanation: Both parties were mutually hostile and did not believe in a possible peaceful coexistence anymore. The Americans and Soviets’ hostility to each other as well as the belief that they could no longer cooperate after the start of the Cold War resulted in the Berlin Blockade.

The correct answer is Option D) Yellow River
The Yellow river is also known as the Huang He and is the second largest river in all of China.
It holds a special place in the history of the country as it is known as the birthplace of the ancient Chinese civilization.
Early civilizations all grew around large rivers which ensured plenty of water and great land.
The Egyptian Civilization grew around the Nile and the Indian civilization grew around the Indus River.
Similarly, the Yellow River gave birth to the early civilization in China, so much so that many historians say that the China we know today would not have existed if there was no Yellow River.
