The correct answers are Universal themes - the bittersweet relationship between siblings, overcoming challenges to achieve one's goals; Culture-Specific Theme- the impact of the September 11 attacks on New Yorker, loss of American Indian culture in European colonies.
Step-by-step explanation:
Universal themes differ from culture-specific themes because universal themes are ideas that can be applied to all or most cultures, despite their location or values. Additionally, universal themes usually occur in all historical periods, and people in different cultures identify with these. This concept applies to "he bittersweet relationship between siblings" and "overcoming challenges to achieve one's goals" because in all cultures and historical periods there has been a relationship of love/hate between siblings, and people often encounter challenges when trying to achieve goals.
On the other hand, themes such as "the impact of the September 11 attacks" or " the loss of American Indian culture" are cultural-specific rather than universal because these do not apply to all cultures and people around the world would not feel identified with these situations. Indeed, these two themes apply to North America but not to other regions such as Africa.
