Step 1: Understanding the Concept:
This question asks about the role of a specific paragraph (the last one) within the context of the entire passage. We need to understand what this paragraph contributes to the author's overall argument.
Step 2: Key Formula or Approach:
The passage first makes a general argument: the experimental course provides an "authentic experience" that teaches valuable lessons. A common rhetorical strategy is to follow a general claim with a specific example to make the claim more concrete and understandable. We should check if the last paragraph serves this function.
Step 3: Detailed Explanation:
- The main body of the passage explains the theory and design of the experimental course.
- The last paragraph shifts from theory to practice by telling the story of one student's specific discovery: finding an error in a major reference work.
- This story is not a summary of all benefits (A), nor is its primary purpose to discuss the canon (B, E) or contrast with the traditional course (D).
- Its function is to be an "illustration" or a concrete example of the "immediate" and "authentic" experiences the course provides. The student's shock and outrage is a powerful example of the engagement the author values.
- Therefore, option (C) is the most accurate description of the paragraph's function. It shows, rather than just tells, what students can get out of the course.
Step 4: Final Answer:
The final paragraph serves as a specific, illustrative anecdote that demonstrates the kind of powerful, hands-on learning experiences the experimental course offers.
