I NEED THE WHOLE DAMN TEST!

To determine which features formed natural barriers to expansion and invasion for China, we need to evaluate the options provided:

A. Bay of Bengal: The Bay of Bengal is located in South Asia and does not serve as a natural barrier for China. Therefore, it can be eliminated as a choice.

B. Gobi Desert: The Gobi Desert is a vast arid region covering parts of northern China and southern Mongolia. As a barren desert with extreme temperatures and challenging terrain, it acts as a significant natural barrier for expansion and invasion. Thus, this option can be considered as a potential answer.

C. Himalayas: The Himalayas are a mountain range situated between the Indian subcontinent and the Tibetan Plateau. They form a formidable natural barrier between India and China. Therefore, the Himalayas can be seen as an obstacle to expansion and invasion. This option can also be considered as a potential answer.

D. Tien Shan mountains: The Tien Shan mountains are a mountain range located in Central Asia, primarily in Kyrgyzstan and Kazakhstan. While they do not directly border China, they can still act as a partial barrier to expansion and invasion from the west. Thus, this option can also be considered as a potential answer.

E. Yellow River: The Yellow River, also known as the Huang He, is one of the major rivers in China. While it is a significant geographical feature, it does not form a natural barrier to expansion or invasion. Therefore, it can be eliminated as a choice.

Based on the analysis of the options, the correct answers are:

B. Gobi Desert
C. Himalayas
D. Tien Shan mountains
