Final answer:
The best structure to use would be time order, which follows the sequence of events in the order they occur. Comparing and contrasting can also be a useful approach to highlight the key differences between the pre-Renaissance period and the Renaissance itself.
Step-by-step explanation:
The best structure to use to describe the events leading up to the Italian Renaissance would be time order, which follows the sequence of events in the order they occur. This structure will provide a clear and chronological account of the events that led to the Renaissance in Italy. For example, you can start by discussing the political and economic changes in Italy during the late Middle Ages, then move on to the cultural and intellectual developments that set the stage for the Renaissance.
Comparing and contrasting can also be a useful approach to highlight the key differences between the pre-Renaissance period and the Renaissance itself. You can examine how the political systems, artistic styles, and societal norms differed before and during the Renaissance. This will help you understand the significant changes that took place during this period.
