To answer these questions:

1. The Aztecs adapted to their environment mainly by A. using terracing and irrigation to farm. This answer is correct as the Aztecs utilized terracing, which is the technique of creating flat platforms on sloped land for agriculture, and irrigation, which involves supplying water to crops through artificial means, to adapt to their environment and maximize their agricultural productivity.

To arrive at this answer, you can eliminate the other options by understanding their characteristics. Option B, living a nomadic hunter-gatherer lifestyle, is not an accurate description of the Aztecs, as they were an agricultural society. Option C, trading peacefully with neighbors, may have occurred to some extent, but it was not a primary means of adaptation. Option D, settling along the coasts where they could fish, is not accurate either, as the Aztecs were located in the Valley of Mexico, which is surrounded by mountains and not coastal areas.

6. The feature of the Aztec capital of Tenochititlán still in use in Mexico City today is A. the Zócalo. This answer is correct. The Zócalo is the main public square in Tenochititlán, which later became the main plaza of Mexico City. It continues to be an important cultural and historical center to this day.

To arrive at this answer, you can eliminate the other options. Option B, the sewage system, is not correct as Tenochititlán's sewage system was advanced for its time but is not directly used in Mexico City today. Option C, the public baths, is also incorrect as the public baths of Tenochititlán were not carried over to Mexico City. Option D, the aqueducts, is not correct either as the aqueducts of Tenochititlán did not survive to be used in Mexico City.

9. A likely major weakness of empires, based on what you learned about the Aztecs, is C. They make enemies. This answer is correct. Empires often face challenges and resistance from those they conquer or come into contact with, which can lead to internal and external conflicts.

To arrive at this answer, you can eliminate the other options. Option A, they lack resources, doesn't apply to the Aztecs as they had a well-developed agricultural system and access to various resources. Option B, they conduct far-flung trade, is not a weakness but rather a strength of empires as it promotes economic growth and cultural exchange. Option D, they have superior weapons, is also not a weakness but rather a potential advantage for empires in terms of military power.
