Analyze the Modern Era section

Using the Oceania History knowledge point
The timeline categorizes historical events into three distinct periods: "Early Times" (red), "The Colonial Period" (blue), and the "Modern Era" (orange). The orange section on the far right spans from approximately 1900 C.E. to 2000 C.E.

Evaluate the events in the Modern Era

Using the Oceania History and Impact of Colonization knowledge points
The events listed under the orange "Modern Era" are:

• 1907: New Zealand gains independence
• 1962: Samoa gains independence
• 1971: South Pacific Forum formed
• 1994: Palau gains independence

Using the Oceania History knowledge point

• Option A refers to the Colonial Period (blue section).
