One main issue in studying global social inequality is: a. most countries keep their economic situations secret. b. social inequality is relative and therefore, difficult to compare across cultures. c. the presence of tourism can make a country look richer than it really is. d. most people live beyond their means which gives a false sense of wealth to a society.

b. social inequality is relative and therefore, difficult to compare across cultures.

Explanation:

The concept of social insecurity occurs when the society is distributed unequally or unevenly through the norms of allocation of resources and endangered species patterns across the norms that define the preference to access to social goods like the power, religion, kinship, the race, the ethnicity, gender, age, and class, etc.  Also linked to the economic and political insecurity. Hence the resource distribution is based o the merits that some societies show over the geographical locations. Being classified as a stratified society thee issues are also related to the treatment and inequality among members. A major example can be a gender gap and the health, income gaps that lead to the formation of global social inequality.
