Why we do dese tests?!?!?

Today I had a 30 question long test on imperialism in Africa and China. I mean, I understand how it was big back then and started a lot of things like the Sepoy revolt and the Opium War and the Boxer rebellion but how will this stuff affect my daily life? Or, how will annotating a book affect my daily life? I mean, we call it talking to the text but, it doesn't even talk back like, dude, where are your manners? At least I got in a demo class and got some rolls and falls today with other requirements.
