Verified step by step guidance

1. Step 1: Understand the concept of economic globalization, which refers to the increasing interdependence and integration of national economies through cross-border trade, investment, technology, and labor movement.
2. Step 2: Analyze each option by considering the typical effects of economic globalization during the twentieth century. For example, globalization generally leads to increased communication and technology exchange, not a decline.
3. Step 3: Recognize that economic globalization tends to increase the movement of labor across borders rather than reduce it, as people seek opportunities in different countries.
4. Step 4: Note that while trade barriers have been reduced in many cases, complete elimination of all trade barriers worldwide has not occurred, so this option is not accurate.
5. Step 5: Conclude that the most accurate effect of economic globalization in the twentieth century is the increased integration of national economies through trade and investment, reflecting the growing interconnectedness of markets.
