The correct answer to this open question is the following.
One way in which policies or monarchs and leaders withstood challenges in the period 1450 to 1750 was because they were absolute rulers of their kingdoms. Absolutism was the factor that favored them because it gave them total and absolute power to exert their will over their territories and people. AS they demanded absolute obedience to their subjects, no act of rebellion was tolerated was heavily punished, even with death. This absolute power helped kings to withstand challenges in the period 1450 to 1750 and to have the allegiance of their kingdoms.

Southern Chinese culture, agriculture and domesticated animals (pigs, chickens and dogs) is believed to have spread from the Philippines through the islands of Indonesia to the islands north of New Guinea. By 1000 B.C., obsidian was being traded between present-day Sabah in Malaysian Borneo and present-day New Britain in Papua New Guinea, 2,400 miles away. Later southern Chinese culture spread eastward across the uninhabited islands of the Pacific, reaching Easter Island (10,000 miles from China) around 500 A.D.
