When using the compare and contrast structure, an author might:

Utilizing the compare and contrast structure involves examining the relationships between two or more subjects by emphasizing both their similarities and differences. The correct choice reflects this approach, as effective compare and contrast writing organizes information in a way that reveals how the subjects connect and diverge. By creating paragraphs that highlight both aspects, the author can provide a comprehensive view that helps readers understand the subjects more deeply.

In contrast, discussing a timeline of historical events does not inherently compare and contrast; it typically provides a sequence of occurrences without emphasizing their similarities or differences. Presenting only the differences would limit the analysis, missing the crucial aspect of finding common ground or shared characteristics, which is essential in a compare and contrast essay. Focusing exclusively on pros detracts from a balanced exploration of the subjects, as it neglects potential cons or opposing viewpoints, which are an important part of understanding the full picture in a compare and contrast format.
