(1) Take a moment and imagine you are traveling in a country you have never been to before. Everything about the sights, the smells, the sounds seem strange. People are speaking a language you do not understand and wearing clothes unlike yours. But they greet you with a smile and you sense that, despite the differences you observe, deep down inside these people have the same feelings as you. But is this true? Do people from opposite ends of the world really feel the same emotions? While most scholars agree that members of different cultures may vary in the foods they eat, the languages they speak, and the holidays they celebrate, there is disagreement about how much culture shapes people's emotions and feelings including what people feel, what they express, and what they do during an emotional event.
What idea does the expression "opposite ends of the world" in Paragraph (1) repeat?
