Question 8

The primary purpose of the passage is to discuss precursors to an important breakthrough in understanding chimpanzees.

The passage highlights the historical context and significance of the discovery of chimpanzees using tools in the wild, illustrating how earlier studies on tool use by psychologists laid the groundwork for this breakthrough.

A) show how approaches to studying ape cognition and tool use have changed over time

While the passage touches on different approaches to studying ape cognition, it does not primarily focus on changes in methodologies over time. Instead, it emphasizes the historical context and significance of previous work leading to the discovery of tool use in chimpanzees.

B) summarize recent research on the significance of tool use in chimpanzees

The passage does not summarize recent research; rather, it reflects on historical discoveries and their implications. It specifically discusses how the finding about tool use in chimpanzees has influenced the field, rather than providing a summary of recent studies.

C) question the extent to which a discovery about chimpanzees was groundbreaking

The passage does not question the groundbreaking nature of the discovery itself but instead presents it as a significant milestone in the study of primatology. It discusses past research and its implications without undermining the importance of the discovery.

D) discuss precursors to an important breakthrough in understanding chimpanzees

This option accurately reflects the passage's focus on the historical significance of earlier studies in tool use and cognition, which set the stage for the groundbreaking discovery of chimpanzees using tools in the wild. The passage connects these precursors to the broader implications for understanding animal behavior.

E) show how work on ape cognition has influenced the study of animal behavior

Although the passage implies a connection between ape cognition and animal behavior, its primary focus is not on the influence of ape cognition research on the broader field. Instead, it centers on the historical context leading to a significant breakthrough in understanding chimpanzee behavior.

Conclusion

The correct answer, D, effectively captures the essence of the passage, which discusses the historical precursors that led to a major breakthrough in understanding chimpanzee tool use. Other options either misinterpret the passage's focus or address aspects that are not central to its main argument, such as recent research or questioning the significance of the discovery.
