Step-by-step explanation:
Using a block structure when there are few items to compare in an essay is a good idea because it can help to make the comparison clearer and more organized for the reader. In a block structure, the writer discusses all the points related to one item before moving on to the next item. This allows the reader to see the similarities and differences between the items more clearly, as they are presented side by side.
When there are only a few items to compare, using a block structure can also help to avoid confusion and make the essay easier to follow. It provides a clear and consistent structure for the writer to follow, and helps to ensure that each point is fully developed and clearly explained.
Furthermore, a block structure can help to emphasize the differences and similarities between the items being compared. By presenting all the points related to one item together, the writer can provide a more detailed and comprehensive analysis of that item, and highlight its unique characteristics. This can help the reader to better understand the differences and similarities between the items being compared.
Overall, using a block structure when there are few items to compare in an essay can help to make the comparison clearer, more organized, and easier to follow for the reader, while also allowing the writer to provide a more detailed and comprehensive analysis of each item.
