Question

What does the information on this map suggest regarding ethnic groups in the southern Balkans?

The Balkan Peninsula’s ethnic variety will eventually cause a war.
The Balkan Peninsula’s largest ethnic group is the Macedonians.
The Balkan Peninsula is home to one ethnic group.
The Balkan Peninsula is the home of a wide variety of ethnic groups.

Answer 1

"The Balkan Peninsula is the home of a wide variety of ethnic groups."

Reason: the map shows many different ethnic groups (Greeks, Albanians, Bulgarians, Serbs, Macedonians, Turks, etc.), not a single group and not evidence about future wars or that Macedonians are the largest group.
