Read passage on multiculturalism from Dinesh DSouza. The essay should be personal, reflecting your thoughts, not a mere restating of DSouza. It may touch on experiences that you have had in encountering other cultures. Or it may involve assumptions that other people have made about you because of your ethnic or racial background. You might want to comment about how you were taught about multiple cultures as part of your schooling. Or how aspects of your culture were omitted from your education. You may even want to ask a parent or a grandparent what they were taught and compare that to what you were taught.
