HELPRead the passage from “Comprehending the Calamity,” in which the author presents the idea that the automobile was a huge help after the earthquake. One pertinent feature of this awful experience of earthquake and fire is the entire change of opinion in regard to the automobile. Its most virulent critics now sound its praise. The railroad and street-car service was destroyed at one blow, and we suddenly appreciated that San Francisco was truly a city of magnificent distances. The autos alone remained to conquer space.

Which answer best describes the organizational structure the author uses to communicate this idea?

1. cause and effect
2. chronological order (Wrong)
3. comparison and contrast
4. classification schemes
