Answer and Explanation:
1. Cultural prejudice was greatly strengthened during European colonialism, where European nations began to invade other nations and view them with inferiority, treating them as belonging to savage people, without culture and with brutality. This happened, mainly among Asian, African and indigenous peoples. This prejudice was intensified when the strengthening of the culture of the USA, who saw themselves as superiors as peoples such as Latinos, Blacks, Asians, Indians and anyone else who did not present customs admired by Americans. This type of prejudice persists today, but it needs to be combated, since all cultures are important, rich and beautiful.
2. Although tests and IQ are not completely impartial, they are important for measuring a generalized intelligence factor, which can present levels of people's mental and cognitive quality.
