how did us general macarthurs landing in korea and successful push toward the chinese border affect the course of the korean war? (1 point)
as macarthurs troops neared chinas border, mao zedong asked the un to help settle the korean war.
observing macarthurs success, the soviet union and china sent guns and warplanes to aid north korea.
as u.s. forces advanced and winter set in, china supplied north korean troops with food and ammunition.
fearing an american invasion in china, mao zedong dispatched troops to support north koreas armies.

Explanation:

When MacArthur's troops neared the Chinese border, China was concerned about potential American invasion. Mao Zedong, fearing for China's security, dispatched troops to support North Korea. This was a significant turning - point in the Korean War.

• Option 1: Mao Zedong did not ask the UN to help settle the war in this context. The UN was seen as being on the side of the US - led forces in a sense.
• Option 2: The Soviet Union and China's aid was more about a strategic response to the US advance near China's border rather than just observing MacArthur's success. And the key action was China's troop dispatch, not just sending guns and warplanes.
• Option 3: While China did support North Korea, the most impactful action was the troop dispatch, not just supplying food and ammunition as the US advanced.

Answer:

Fearing an American invasion in China, Mao Zedong dispatched troops to support North Korea’s armies.
