The age of exploration" and the 18th century the "age of reason

Just as historians/commentators in the past called the 16th century "the age of exploration" and the 18th century the "age of reason", you are tasked with deciding what we will call the 20th century from a global history perspective. Use specific examples from the 20th century that come from at least four continents to illustrate and explain your top three considerations for the name of the century and then explain which of the three you think is the best and why.

Please use MLA citations with in text citations and list of works cited.
