The correct answer is A) It had a complex system of canals, bridges, and dams, with the Great Temple at the center.
The statement that is true of the Aztec capital, Tenochtitlán is "It had a complex system of canals, bridges, and dams, with the Great Temple at the center."
Tenochtitlan was the capital city of the Great Aztec empire in Mesoamerican times. It was located in what today is downtown Mexico City. The city was built over a lake, the Texcoco Lake. That is why they built a complex system of canals, bridges, dams, and chinampas around the main ceremonial center with the two high pyramids to honor Aztec's gods Huitzilopochtli (War) and Tlaloc (Rain).
The Crusades were a series of religious wars between Christians and Muslims started primarily to secure control of holy sites considered sacred by both groups. In all, eight major Crusade expeditions occurred between 1096 and 1291. The bloody, violent and often ruthless conflicts propelled the status of European Christians, making them major players in the fight for land in the Middle East.

The correct answer to this open question is the following.
Although there are no options attached we can say the following.
The scientific data that encouraged nations to protect the environment is the level and air pollution produced in major cities of the world with their industries, as is the case of the United States of China. The same for air and water pollution.
Another reason is the evidence of climate change due to global warming.
Other important scientific data is the soil degradation in lands that used to be very fertile to grow crops. Most countries have overexploited raw material and non-renewable natural resources. Jungles and forests are faced with biodiversity loss and deforestation due to excessive industrial practices.
Regarding the sea, most oceans present acidification and plastic trash in different regions of the oceans.
The problem is that major industries around the world did not have any respect or consideration for taking care of nature. These industries were only interested in big profits no matter what. They produced their goods and polluted the air, polluted the water, and also contributed to noise pollution.
