Final answer:
Russia's historic expansion and strategic location, as well as its substantial natural resources and maneuvering in global politics, make it a potential 'power dealer' in global exchange. Its alliances, particularly with China, and influence on energy markets underscore its importance on the world stage.
Step-by-step explanation:
In determining why Russia should be considered a "power dealer" in the global exchange, option B ('Russia has always strived to be a power dealer and negotiates the treaties') and option C ('Russia is in an ideal location for trade and travel, and the size covers two continents') both provide insight into Russia's historical and geopolitical significance. Russia's vast territory and strategic location make it a pivotal player in intercontinental trade and global politics. Throughout history, including during the times of Peter the Great and Catherine the Great, Russia expanded its influence and secured access to critical ports on the Baltic and Black Seas.
By the 21st century, despite economic challenges and political sanctions—like those due to the 2022 invasion of Ukraine—Russia maintained a significant role in international affairs, partly because of its strategic alliances with countries such as China. Also, considering its large size and resources, Russia has a considerable impact on global energy markets and the geopolitical landscape. Therefore, Russia's combination of geographic advantage, resource endowment, and active foreign policy makes it apt to be considered a "power dealer" in terms of global trade and influence.
