Ooooo, it looks as if you need to read up on the Incas and Mayas. Use your textbook and or these:

http://en.wikipedia.org/wiki/Maya_civilization

http://en.wikipedia.org/wiki/Andean_civilizations#Inca_Empire

I think both of your answers are correct. Double check on the Mayan crops, though.

For the others, I'm sure your text materials contain the information. If not, type the question (or keywords from the question) into your search engine (Google, Bing, whatever you use), and hit "enter". You'll get a list of related articles. If you don't find what you need, type in a different keyword(s) and try again. We won't do your work for you and give you the answers.

To answer this question, we need to consider the agricultural practices of the Incas. Again, we can reference historical sources or consult experts in the field. The correct answer is C. they built terraces on the mountainsides. The Incas constructed terraces on steep mountains slopes, which allowed them to create flat land for farming and maximize their agricultural productivity.

3. Which crop was the most important to the Mayas?

D. peppers

To determine the most important crop to the Mayas, we can again refer to historical research or consult reliable sources. The correct answer is A. corn. Corn, also known as maize, was a staple crop for the Mayas and played a significant role in their agriculture, economy, and diet.

The correct answer is C. building island gardens. The Aztecs created chinampas, which were artificial islands used for agriculture, particularly for growing crops like maize, beans, and squash. These floating gardens allowed them to increase their agricultural output in the challenging environment of the lake region in which they lived.
