Final answer:
The boundaries that are not easily drawn are between political culture and cultural identity. The correct answer is option: D) The boundaries between political culture and cultural identity.
Step-by-step explanation:
In the statement, the boundaries that are not easily drawn are between political culture and cultural identity (D). Political culture refers to the shared attitudes, values, goals, and practices common to members of a political group, while cultural identity relates to the shared attitudes, beliefs, customs, and behaviors of a particular cultural group.
These boundaries are difficult to draw because culture is a comprehensive concept that can be difficult to quantify, and individuals can have multiple cultural identities that may intersect with their political culture. Furthermore, the overlap between political culture and cultural identity can aggravate existing differences, which are not accounted for in political science research.
