Changed election procedures.

Explanation:

In order to prevent events from the 1796 election, when two differently oriented candidates were elected president and vise-president (Adams and Jefferson), the United States adopted the 12th amendment. It had become obvious that things needed to change.

The 12th amendment changed election procedures in a way that it entitled every elector to choose both a president and a vice-president.

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.
