A. Artificial islands used for farming

The answer is A. artificial islands used for farming.

Chinampas are artificial islands that were used for farming by the Aztec civilization in ancient Mesoamerica, which is now modern-day Mexico. They were created by digging canals and then using the excavated soil to build up small raised beds of fertile land. These beds were surrounded by water from the canals, which provided irrigation to the crops grown on the chinampas.

To find the answer to this question:

1. Start by understanding the term "chinampas." If you are not familiar with it, you can search for the term in an online search engine to gather basic information. This will give you a general idea of what chinampas are and their historical significance.

2. Proceed to check the given options. Read each option carefully and try to eliminate any obviously incorrect answers. In this case, options C and D are clearly unrelated, so they can be eliminated.

3. Analyze the remaining options. Option B, "crops grown by Aztec farmers," is a good contender, but it does not accurately describe what chinampas actually are. Chinampas are the artificial islands used for farming, not the crops themselves. Therefore, option B can also be eliminated.

4. The only option that accurately describes what chinampas are is option A, "artificial islands used for farming." This is the correct answer.

Remember, even if you are not familiar with the exact topic, you can use the process of elimination and logical reasoning to find the correct answer. It is always good to do some additional research to gather more information and enhance your understanding of the topic.
