Step 1: Understand the question
We are asked why the primary function of a scholar is different from the search for a cure for cancer. The key lies in distinguishing between curiosity-driven scholarship and consequence-driven research.
Step 2: Recall the relevant passage lines
The passage explains: "It is true that scholars can be put to work answering questions for the sake of the consequences as thousands are working now, for example, in search of a cure for cancer. But this is not the primary function of the scholar, for the consequences are usually subordinate to the satisfaction of curiosity."
Step 3: Interpret the meaning
- The main function of a scholar is to satisfy curiosity, to ask and answer questions because they want to know.
- In contrast, research like the search for a cure for cancer is pursued not only for curiosity but mainly because of its practical consequences. It is systematic, planned, and involves the efforts of many scholars working towards a tangible result.
- Thus, the distinction is that curiosity-driven work is inwardly motivated (knowledge for its own sake), whereas cancer research is outwardly motivated (knowledge for a direct and critical purpose).
Step 4: Conclusion
Therefore, the primary function of a scholar differs from cancer research because the former seeks satisfaction of mental curiosity, while the latter is a deliberate, planned, and collective pursuit motivated by the consequences of finding a cure.
Final Answer: The correct option is (C): the primary function of a scholar is satisfaction of his mental curiosity, while research involving a cure for cancer demands a constant, systematic and planned pursuit by several scholars.
