Read this excerpt from a website Emmanuel has found: On March 25, 1911, a preventable fire killed 146 helpless workers in New York City’s Triangle Shirtwaist Factory.

The worst offense, however, was that the greedy owners had locked the door to the stairs to prevent employees from taking breaks and from stealing supplies. Emmanuel realizes the source is not neutral. What is the tone of the excerpt? A. angry B. cautionary C. neutral D. supportive
