Fischer and Ravizza (1998)
Validity: The premises are explicitly stated in the passage and together they rationally support (not attack) the conclusion that strong reasons-responsiveness cannot be required for guidance control, since many responsible agents fail to meet its demanding standard—though the argument type is mislabeled as "attack," the premises do logically support the stated conclusion and the argument is clearly present in the passage.
Confidence: Clearly stated argument in the text.
