defending a countrys borders against those who wish to take over its valuable resources is a necessity.
people are likely to dispute borders when they believe their political concerns are not being heard.
borders built around people with similar ideologies are most likely to be stable and successful.

Explanation:

Excerpt #1 shows that when people with shared political beliefs (similar ideologies) are grouped within a district (a kind of border - like entity), the representative needs to be aware of their interests. Excerpt #2 shows that Sudan and Southern Sudan, which are ethnically and religiously (ideologically) distinct, have a non - disputed border. This implies that when borders are around people with similar ideologies (as in the U.S. congressional districts where shared political beliefs matter and in the Sudan - Southern Sudan case where distinct ideologies lead to a non - disputed border), there is a certain stability.

Answer:

D. Borders built around people with similar ideologies are most likely to be stable and successful.
