The most prominent evidence would be regions and their cultures. Personally, I don’t know much about Canada, but the U.S. is a land built off of other countries immigrating. Even though the majority is now Americanized Caucasian people, there are still prominent cultural regions within the borders. For example, Louisiana is known for its Cajun culture, which stems from the French. Also, the South is more populated with African Americans due to the history of slavery (sad but true). Also in California, although diverse, there is a huge population of Filipinos and other Asians due to the immigration during the 1920s and discrimination back then.
As for the arts, these regions affected cultural life and created artifacts and art for modern society to analyze and enjoy. With these new eras, art comes in movements. One that stands out to me is the Harlem Renaissance in NY during the 1920s. Many former and runaway slaves seeked refuge in this crevice of Manhattan and expressed themselves through art, music/jazz, dancing, etc. Other regions have their own culture within that hand shaped the arts, as well.
An ethical concern is a problem that requires someone to choose between alternatives to label something as "right" or "wrong", hence the ethical part.
So, I assume that ethical concern, regarding research, is when you must label different sources as obtaining proper information, or if it's incorrect(?).
I'm only guessing here, sorry, but that's the best I have.
Ima be honest, I’m just here for the points
