Read LOTS and let us know what you decide.

To determine the correct answer to this question, let's analyze each option and see which one aligns with the statement provided.

a) Developing a calendar to know when to plant: This option suggests that the Maya civilization's power was due to their ability to accurately determine the timing for planting crops, such as corn, through the use of a calendar. While understanding the seasons and optimal planting times was indeed important for agricultural societies, it is not the primary reason why corn cultivation made the Maya civilization powerful.

b) Limiting irrigation systems: This option implies that the Maya civilization's power stemmed from their restricted use of irrigation systems. However, limiting irrigation systems would have a negative impact on agriculture, as it would reduce access to water for crop growth. Therefore, this option is unlikely to be the correct answer.

c) Providing plenty of food and a surplus to trade: This statement indicates that corn cultivation led to an abundance of food for the Maya civilization, which they could trade with others due to the surplus. This option aligns with the idea that corn cultivation contributed to the Maya civilization's power. Corn was a staple crop that provided sustenance and allowed the Maya to have enough food to sustain their growing population and engage in trade activities. Therefore, this option seems to be the most accurate.

d) Causing city-states to go to war: This choice implies that corn cultivation played a role in provoking conflict and wars between city-states within the Maya civilization. While agricultural resources can be a cause of conflicts throughout history, there is no direct correlation between corn cultivation and city-states going to war in the Maya civilization.

Considering the options provided, it appears that option c) "providing plenty of food and a surplus to trade" is the most plausible answer. So your intuition is correct, the Maya civilization became powerful because corn cultivation provided them with sufficient food and surplus to engage in trade.
