Reading comprehension—best supported inference (autonomy of art): The passage states that art admits no rule or interference external to itself; only art should touch the work to bring it into being, and nothing should attain the work except through art itself. What conclusion does this best support?

Given data

• Art rejects external interference or rule.
• Only art itself should shape and reach the work.

Concept / Approach
The doctrine described is the autonomy of art: artistic creation is self-justifying and self-governing, not subordinated to outside ends.

Step-by-step reasoning
Step 1: If nothing external should govern the work, art is not for politics, utility, or social ends.Step 2: Thus, the most precise summary is that art exists for art itself.Step 3: Option C captures this. Options A, B, D, and E insert external governance or mixed purposes not endorsed by the passage.

Verification / Alternative
Phrases like “nothing shall attain the work except through art itself” are classic formulations of art-for-art's-sake.

Common pitfalls

• Softening the autonomy claim by adding “and life,” which the passage does not allow.

Final Answer
art is for the sake of art alone.
