Question 33

The event that triggered the chain of events leading to WWI on June 28, 1914, was the assassination of Archduke Franz Ferdinand in Sarajevo. Austria's ultimatum, Serbia's rejection, and Russia's mobilization were subsequent events.

Charles Darwin's major work where he developed the theory of evolution by natural selection is "The Origin of Species". "The Descent of Man" focused on human evolution, and the other options are not his primary work for natural selection theory.

Answer:

d) Archduke Franz Ferdinand was assassinated in Sarajevo.
