5. In context, the metaphor in the third sentence ('it was only a subplot in a historical drama of time, place, and people that had been playing for thousands of years') chiefly serves to:
Answer: D
The metaphor chiefly serves to place the Lewis and Clark expedition into a broad context.
The metaphor highlights that the Lewis and Clark expedition is just one part of a much larger historical narrative that encompasses thousands of years of history prior to their journey. This perspective emphasizes the importance of understanding the expedition within the broader continuum of the region's past.
A) call attention to the age of the United States as a nation
This option is incorrect because the metaphor does not focus on the age of the United States itself, but rather on the extensive history of the West before the expedition. The emphasis is on the depth of history in the region rather than on the relatively young age of the nation.
B) question the literary value of the writings by Lewis and Clark
This option is also incorrect as the metaphor does not critique or diminish the literary value of their writings. Instead, it places their accounts within a larger historical context, suggesting that while their writings are significant, they are not the entirety of the region's history.
C) trivialize the accomplishments of the Lewis and Clark expedition
This choice misinterprets the metaphor's intent. While it suggests that the expedition is a subplot, it does not trivialize their accomplishments; rather, it recognizes that their journey is part of a much larger historical framework. The expedition is acknowledged as important, but not the sole defining event.
D) place the Lewis and Clark expedition into a broad context
This option is correct as the metaphor effectively situates the expedition within a larger historical narrative. It suggests that the events surrounding the expedition are interconnected with a longer history of the West, thus providing a richer understanding of its significance.
Conclusion
The metaphor serves to effectively place the Lewis and Clark expedition within a broader historical context, illustrating that their journey is just one part of an extensive narrative that predates it. This interpretation underscores the importance of recognizing the historical depth of the American West, while the other options either misinterpret or fail to capture the main idea conveyed by the metaphor.
