Question

which economic activity is most associated with highly developed countries?
a subsistence agriculture
b secondary manufacturing
c tertiary and quaternary services
d primary resource extraction

Explanation:

Subsistence agriculture (A) is typical of less - developed regions where people grow food mainly for their own use. Secondary manufacturing (B) is more associated with industrializing or developing economies. Primary resource extraction (D) is common in economies that are rich in natural resources but not necessarily highly developed. Highly developed countries have economies that are service - oriented, with a large portion of their economic activity in tertiary (service - based like education, healthcare) and quaternary (knowledge - based like research, technology) services. So the economic activity most associated with highly developed countries is tertiary and quaternary services.

Answer:

C. Tertiary and quaternary services
