Final answer:
Many people who immigrate to the United States bring with them different traditions from their common cultural background, contributing to the cultural diversity in the U.S.
Step-by-step explanation:
The question you asked pertains to what immigrants often bring with them when they come to the United States. Many people who immigrate to the United States come from a background with a common cultural background, bringing with them different traditions. This can include a variety of cultural attributes such as language, food, religious practices, and social norms. While immigrants do enter different time zones when they move, and they must deal with currency exchange upon arrival, neither of these is inherent to their cultural backgrounds. Likewise, while they may speak different languages, language is a facet of culture rather than a separate import. Therefore, C) Traditions is the correct answer. Immigrants contribute to the rich cultural mosaic of the United States through the various traditions they bring and sustain.
