Answer:

B. External validity

Explanation:

External validity- It refers to the extent through which a conclusion made from the research study can be generalized to the person outside the study.

Generalization is of three types: environmental, temporal, and population.

Threats to external validity:

1. History effects & maturation.

3. Constructs, confounding, and methods.

4. The 'experimental world' versus the 'real world'.

The kurds have a long history as ethnic group , being in middle east. Bein identified themsevles apart from Arabic majorities and having a more progressive , secular, and western orientation, they fail still to be recognized as a state nation.

This is why Conflict theorists would argue in the case of Kurds:

Why the society has failed or why kurds have not been assimilated and giving a function and meaning?

Then they would see society as divided into groups each with different power and resources that are in a dynamic of constant struggle and exploit with one another (Turkey vs Kurds)
