So every government can have a set of rules in their area without having conflict.
The answer is: Role Strain
Example of this would be when a supervisor of a company is dating her co- workers.
In such situation, she has two different roles. One is as a boss that has to be strict and have a set of expectation that must be fulfilled by employees. On the other hand, she is also a girlfriend that has to give a full support to his loved one.
When her boyfriend make a mistake in the office, it could create a confusion for her since she's unsure which role she need to assume to deal with it.
Plants and animals have to be able to cope with the environment. (An animal that is good at keeping in heat would not do well in a desert.)
This is kinda hard sense they do produce a lot of major industries in the U.S like natural gas, tourism, etc.But as for the BEST answer I'd say D)
