Final answer:
The phrase 'pas de deux' in the context of 'How the Cold War Changed Education' refers to an intertwined relationship, reflecting the complex dynamic between the United States and the Soviet Union during the Cold War.
Step-by-step explanation:
The phrase pas de deux is a ballet term commonly used to describe a dance duet in which two dancers, typically a male and female, perform ballet steps together. It literally translates to "step of two" in French. When used metaphorically in other contexts, such as in the article "How the Cold War Changed Education," it signifies an intertwined relationship rather than a literal dance. This metaphor is fitting for the Cold War context, as it indicates the complex and interconnected relationship between the two superpowers, the United States and the Soviet Union, during the Cold War period. Their relationship was marked by competition and strategic movements resembling a dance, where both parties were closely paying attention to each other's actions while maintaining a delicate balance. Therefore, the correct answer to the student's question is (D) an intertwined relationship.
