Answer and Explanation:
The author of the passage uses rhetorical resources to make the text more fluid and more effective, reaching the reader intensely about certain elements of the construction of the racicion, highlighting important points in the text. In the text above, the author does just that and uses resources to make the text more accessible, clear and very punctual, allowing several readers to be moved in relation to what is being narrated.
In the text shown above, we can see that the author used the resources called "Logos" and "Pathos", to promote logical reasoning and stimulate the readers' emotional about the subject commented. The logos were used in the lines "The city was nearly leveled, but only about 2,000 people were killed. Without the warning, easily 150,000 would have died," showing a logical argument that shows how the detection and warning of possible earthquakes is efficient. Later on, the author uses the pathos on the lines "I decided that if I could do anything — anything — to save lives lost to earthquakes, it would be worth the effort" where it touches readers and shows an emotional feeling towards the text.
