By the nineteenth century education and industrialization became the focus of japan but the way of the warrior was strong and the class system was stricktly enforced with the samurai as the most important social class. true or false?

False.

Explanation:

Japan began its drive toward modernization and catch-up with the West in the Meiji Era (1868-1912).  The shogun lost his power, the emperor played a more significative role and a new elite administrated the state.  Western models and patterns were adopted, official missions were sent to the most advanced countries to study their modern educational, administrative, industrial, defense, commercial and scientific systems and solutions. There was no more place for the samurais and their lifestyle. Some members of the old samurai class simply became part of the new elites. The old samurai way of life simply died. However, Japan retained many unique elements of its culture and idiosyncracy.

the fact that could also be added to column b is that during world war ii, specifically between the years 1941 and 1945, japan expanded its territory towards the indonesian territory in what was known later as part of the "pacific war". in that time, japan could conquer the philipines, singapore,   borneo, central java, malang, cebu, sumatra and various other islands of the area, therefore expanding its territory for a brief period of time.
