Ethnic and linguistic obstacles to economic development may

Ethnic and linguistic obstacles to economic development may be overcome through
a) Political and economic reform
b) Use of colonial languages or dominant cultural group dialects/languages
c) Plentiful resources

Solution

Otion B is correct

Having plentiful resources does not seem to provide any help in economic development when communication with the people is not possible. The natives should be well aware of the development process and hence if the region was colonized, the use of colonial languages should be preferred. Otherwise their native or dominant cultural group dialects can be used to make the communication. Political reform in areas also require the understanding of the community which can not be possible without appropriate understanding of the language and culture.
