Step by step, the third volume of "Step by Step" provides comprehensive answers and original texts for Unit 1, focusing on World News and International Relations. This volume emphasizes the importance of self-determination in determining one's direction, contrasting the way a tree's direction is determined by the wind with how individuals must take responsibility for their own paths. The materials highlight the significance of belief in shaping life and the weight of carrying out a mission. In this unit, the Tapescripts reveal that the former American Defense Secretary William Perry has suggested a significant shift in policy towards North Korea. Additionally, hundreds of thousands of mothers in the United States have united in Washington to advocate for stricter gun control laws. These news stories serve as examples of the global issues addressed in the unit, highlighting the interconnected nature of international relations. Through these materials, readers are encouraged to examine the complexities of world news and their impact on diplomatic relations. The emphasis on individual responsibility and belief systems underscores the role that personal values play in shaping one's interaction with global events. By providing detailed answers and original texts, this volume equips readers with the tools to analyze and understand the intricate web of international relations.

uncertainty in the marketplace is setting us up for some very good values in the market."
