The best description of the downfall of Greek city-states would be prolonged war.

The best answer to the question, "Which of the following best describes the downfall of Greek city-states?" is prolonged war.

To arrive at this answer, we need to understand the key factors that led to the downfall of Greek city-states. One of the main factors was indeed prolonged war. The ancient Greek city-states were constantly engaged in wars with each other, such as the Peloponnesian War between Athens and Sparta. These wars were often long-lasting and highly destructive, leading to the weakening and eventual collapse of many city-states.

To find the answer to this question, you could have eliminated the other options - food desert, urban penalty, and urban blight - as they do not accurately describe the downfall of Greek city-states.

A food desert refers to an area where access to fresh, healthy food is limited. This concept does not relate directly to the downfall of Greek city-states.

Urban penalty and urban blight are terms used in urban studies to describe negative aspects of urban areas, such as high crime rates, poverty, or dilapidated infrastructure. Although urban issues could have contributed to the decline of Greek city-states to some extent, they are not the primary factors that led to their downfall.

By analyzing and eliminating the options that do not fit the historical context, we can conclude that the most appropriate choice for the downfall of Greek city-states is prolonged war.
