How were the invasions of China and Poland different?
a- The Nazi invasion of Poland was opposed by Western nations, while Japan’s invasion of China was not.
b- The invasion of China started World War II.
c- The invasion of Poland started World War II.
d- The Nazi invasion of Poland took longer than Japan’s invasion of China.
c- The invasion of Poland started World War II.
The correct answer is c. The invasion of Poland by Nazi Germany on September 1, 1939, is considered the event that triggered the outbreak of World War II. On the other hand, Japan's invasion of China began in 1937, a couple of years before World War II officially started in Europe. Additionally, option a is incorrect because Western nations did oppose Japan's invasion of China through economic sanctions and various diplomatic actions. Option b is incorrect as it was the invasion of Poland, not China, that started World War II. Lastly, option d is not a significant differentiating factor as the durations of the invasions were not particularly relevant in this comparison.
