The option that is not a trade-off for students who spend a semester abroad is experiencing the culture of another country.
Trade-offs typically refer to the sacrifices one must make in exchange for something else. In this case, missing family activities at home, eating all of their favorite foods, and seeing friends from home daily are all sacrifices that students might experience while studying abroad. However, experiencing the culture of another country is one of the primary benefits of studying abroad, rather than a trade-off.
