Best answer

Answer: A. (1) c and d

Answer: (1) c and d

An index number is a statistical device that measures relative (percentage) changes in an economic variable or a group of variables, such as prices or production, over time or place. It is called a specialised average because it averages changes in items expressed in different units. It is a statistical/economic tool, not a geographical one, and it has nothing to do with air pressure.
