The correct answer is A) He appeals to the audience's emotions.
Roosevelt supported his position that employees should receive compensations in case of an injury or death in paragraph 4 in that "He appeals to the audience's emotions."
We are referring to US President Theodore Roosevelt's speech about labor legislation, delivered in March 1908. President Roosevelt said: "In addition to a liability law protecting the employees of common carriers, the Government should show its good faith by enacting a further law giving compensation to its own employees for injury or death incurred1 in its service. It is a reproach to us as a Nation that in both Federal and State legislation we have afforded less protection to public and private employees than any other industrial country of the world."
President Roosevelt tried to use Pathos, or the emotional approach to convince his audience.
The word "striking" means something remarkable, memorable and that had a strong impact in a given situation. The narrator of the text uses this word to refer to remarkable, impacting, minutable and significant moments that happened in his life, to the point of "making my story" as he says. The sentence "make my story" is what reinforces the meaning of "striking" within this context.
