Answer:
D). He appeals to the audience's emotions.
Step-by-step explanation:
In this given excerpt from President Roosevelt's labor legislation speech delivered in 1908, he employs 'pathos' i.e. 'emotional appeal' in paragraph 4 to convince the readers' that the employees must 'receive compensations in case of death or injury during the service. The descriptions like 'reproach to us as a nation' by not being able to 'afford protection to the public and private employees' unlike other countries help the author to arouse the emotions of the reader and gain their sympathy and eventually their acceptance to his claim. Thus, option D is the correct answer.
