An essay that shows why a location has become polluted is an example of

a. organization by degree
b. chronological order
c. main idea and supporting details
d. comparison-and-contrast
e. None of the above
I think it is either c or e as I think cause-and-effect order can be used in this case.
Please help. Thank You.

Yes, C -- main idea (effect) and supporting details (causes)

You are correct in thinking that cause-and-effect order can be used to explain why a location has become polluted. This order would involve identifying the causes of pollution and explaining how they have resulted in the polluted state of the location.

However, among the given options, the essay example that best matches the description is "c. main idea and supporting details". In this type of organization, the essay would have a clear main idea or central topic (in this case, the location becoming polluted) and then provide supporting details such as the causes and specific examples of pollution in that location.

Therefore, the most accurate answer to the question is c. main idea and supporting details.
