This is illustrated in communication accommodation theory.
The theory was first proposed by Howard Giles in the 20th century. According to the theory, we try to accommodate into our partner's communication as much as they are trying to accommodate into ours. So in this case, both Brenda and her American friends have been trying to adapt to each other's behavior when it comes to communication.
A. 14.4 miles per gallon
B.15 miles per gallon
C. Mr. Walters's car is getting the better mileage per gallon
This can be interpreted two ways:
"Rule of all" can be interpreted as "all have rule", or a direct-democracy, in which every citizen has a voice of the government.
"Rule of all" can also be interpreted as "having rule over all", or monarchy (or totalitarian), in which one or a few have rule over all the subjects in their territories.

Modern law.
Like an example is that the Ten Commandments lists that "You shalt not steal". Now in law, they have made laws, that you cannot steal and what punishment you will get if you do.
Hope this helps :)
