1- The answer is B.

Japan invaded and took over Manchuria (northern China) in 1931. They justified their actions by claiming they were freeing the local Manchus from Chinese rule. This occupation lasted until the Soviet Union and Mongolia's Manchurian Strategic Offensive Operation in 1945.

In 1937, the Second Sino-Japanese War began following the Marco Polo Bridge Incident, during which Japan advanced into the southern territories of China.

2- The answer is B.

Tensions between the U.S. and Japan grew due to the Second Sino-Japanese War and Japan's occupation of French Indochina from 1940 to 1941. This culminated in an embargo from America on strategic materials, such as oil and scrap metal, which Japan relied on heavily for their naval operations.

3- The answer is A.

In a surprise move in 1941, Japan attacked Pearl Harbor, intending to devastate the U.S. Pacific Fleet and diminish American resolve. The Japanese believed the attack's brutality would deter the United States from interfering with their efforts to dominate Southeast Asia.

1.) In 1931, Japan's aggression in East Asia began with the invasion of Manchuria and subsequently escalated with a severe assault on China (particularly the southern region).

2.) In 1940, Japan's attack on French Indochina aimed to suffocate all imports into China, including American military supplies. This action led to the United States imposing an embargo on all oil exports to Japan. (This is likely tied to natural resources.)

3.) A surprise strike on Pearl Harbor was launched by Japan to completely eliminate any possibility of U.S. forces countering their seizure of the Philippine Islands.
