Question

Which research sources are examples of secondary sources? Select two options.

a copy of the Treaty of Versailles
a documentary about the American Civil War
an encyclopedia entry about the Spanish-American War
a government chart showing official census data from 1920
a televised interview with a survivor of the sinking of the Titanic

Answer 1

- a documentary about the American Civil War
- an encyclopedia entry about the Spanish-American War

These are secondary sources because they interpret, summarize, or analyze primary materials (whereas the treaty, the census chart, and the survivor interview are primary sources).
