How was marakanda protected, and how high is the wall?

Marakanda was protected because of its wall and it was surrounded by a moat.  The high walls were made up of mud bricks and clay.  The height of the wall was 11 meters and they were 8 to 9 meters thick.  It maintained its military importance until the 18th to 19th century.

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.

the supreme court can hear any case it wishes as long as four justices agree to hear it.
