According to the diagram, which country is closest to a pure market economy?

there are many answers to this question, such as a diplomat, ambassador, soldier, united nations employee, cia, etc.

i am only doing this for the points.

the answer is a. the harappan civilisation is also called the indus valley civilisation, this is because they built their cities along the indus river. the reason behind this location can be found in the rest of the "old world" civilisations like mesopotamia or egypt, the first built their cities along the rivers tigris and euphrates, the second along the nil; : their respective civilisations thrived because the overflowing of their respective rivers produced favorable conditions for agriculture, their main support.
