Question

why do developing countries usually have less variety in their economic activities?
limited access to education means that people are not trained to work in industry or technology.
focusing on one or two economic activities leads to more rapid economic development.
developing countries are usually small and have limited populations and resources.
people prefer the lifestyle that accompanies traditional activities such as farming.

Explanation:

Limited access to education restricts the skill - set of the workforce in developing countries. This lack of trained personnel in industry and technology limits the variety of economic activities. Focusing on a few activities may not be the main reason for less variety. Size and population are not the primary factors for limited economic variety. Preferences for traditional lifestyles are not the main cause of less economic variety.

Answer:

Limited access to education means that people are not trained to work in industry or technology.
