In China, urbanization increased as the population grew and as the division of labor grew more complex. Large urban centers, such as Nanjing and Beijing, also contributed to the growth of private industry. In particular, small-scale industries grew up, often specializing in paper, silk, cotton, and porcelain goods. For the most part, however, relatively small urban centers with markets proliferated around the country. Town markets mainly traded food, with some necessary manufactures such as pins or oil. Despite the xenophobia and intellectual introspection characteristic of the increasingly popular new school of neo-Confucianism, China under the early Ming dynasty was not isolated. Foreign trade and other contacts with the outside world, particularly Japan, increased considerably. Chinese merchants explored all of the Indian Ocean, reaching East Africa with the treasure voyages of Zheng He.
Where did Chinese merchants explore? 
****
The answer: all of the Indian Ocean

Development Testing is a software development process that involves synchronized application of a broad spectrum of defect prevention and detection strategies in order to reduce software development risks, time, and costs. It is performed by the software developer or engineer during the construction phase of the software development lifecycle. Rather than replace traditional QA focuses, it augments it. Development Testing aims to eliminate construction errors before code is promoted to QA; this strategy is intended to increase the quality of the resulting software as well as the efficiency of the overall development and QA process.
What method is used that involves synchronization of a application?
****
The answer: Development Testing

Secretary of War Elihu Root (1899–1904) led the modernization of the Army. His goal of a uniformed chief of staff as general manager and a European-type general staff for planning was stymied by General Nelson A. Miles but did succeed in enlarging West Point and establishing the U.S. Army War College as well as the General Staff. Root changed the procedures for promotions and organized schools for the special branches of the service. He also devised the principle of rotating officers from staff to line. Root was concerned about the Army's role in governing the new territories acquired in 1898 and worked out the procedures for turning Cuba over to the Cubans, and wrote the charter of government for the Philippines.
Who was the Secretary of War who modernized the US military at the beginning of the 20th century?
****
The answer: Elihu Root


The problem: Answer a question about this article:
The brain contains several motor areas that project directly to the spinal cord. At the lowest level are motor areas in the medulla and pons, which control stereotyped movements such as walking, breathing, or swallowing. At a higher level are areas in the midbrain, such as the red nucleus, which is responsible for coordinating movements of the arms and legs. At a higher level yet is the primary motor cortex, a strip of tissue located at the posterior edge of the frontal lobe. The primary motor cortex sends projections to the subcortical motor areas, but also sends a massive projection directly to the spinal cord, through the pyramidal tract. This direct corticospinal projection allows for precise voluntary control of the fine details of movements. Other motor-related brain areas exert secondary effects by projecting to the primary motor areas. Among the most important secondary areas are the premotor cortex, basal ganglia, and cerebellum.
The red nucleus controls what part(s) of the body?
****
The answer:
coordinating movements of the arms and legs
