Commentator: In last week’s wreck involving one of Acme Engines

Commentator: In last week’s wreck involving one of Acme Engines’ older locomotives, the engineer lost control of the train when his knee accidentally struck a fuel shut-down switch. Acme claims it is not liable because it never realized that the knee-level switches were a safety hazard. When asked why it relocated knee-level switches in its newer locomotives, Acme said engineers had complained that they were simply inconvenient. However, it is unlikely that Acme would have spent the $500,000 it took to relocate switches in the newer locomotives merely because of inconvenience. Thus, Acme Engines should be held liable for last week’s wreck.

The point that Acme Engines spent $500,000 relocating knee-level switches in its newer locomotives is offered in the commentator’s argument as

(A) proof that the engineer is not at all responsible for the train wreck

(B) a reason for believing that the wreck would have occurred even if Acme Engines had remodeled their older locomotives

(C) an explanation of why the train wreck occurred

(D) evidence that knee-level switches are not in fact hazardous

(E) an indication that Acme Engines had been aware of the potential dangers of knee-level switches before the wreck occurred
