Ancient Civilizations

Chinampas were artificial or raised farming plots made in the shallow lake environment around the Aztec capital, Tenochtitlan. People used reeds, soil, and organic material to create productive strips of land surrounded by water. This method adapted farming to a place where ordinary dry fields were limited. Water helped keep the plots moist, and the system could produce food close to the city. Therefore, option A correctly describes chinampas as cultivable plots created in lake areas.

The environmental adaptation is the important idea. Instead of trying to remove the lake completely or copy a farming system from a dry region, the Aztecs used the local water landscape to support agriculture. Chinampas were not pyramids, Roman political institutions, or places for storing mummies. The reference to Tenochtitlan is useful because that city was built in a lake region where this agricultural technique became especially notable. The supplied answer A is accurate and the explanation correctly connects the system with local lake conditions.

Quipu was a system of knotted cords used for calculations and administrative records such as taxes and labour. The road network enabled messengers, armies, and goods to move across distant parts of the empire. Studying them together therefore shows how the Incas governed and communicated across a vast territory. The religious-objects option is a close distractor because some Inca objects had ritual significance, but the main shared role of quipu and roads was administrative. Exam tip: link quipu with record-keeping and Inca roads with communication and imperial control.

The Twelve Tables clarified Roman law in written form. Connect them with legal tradition.

Pax Romana means the long period of relative peace and political stability in the Roman Empire. Stable government reduced wars, disorder, and danger on important roads and sea routes. Because merchants and travellers could move with greater confidence, trade expanded between provinces and distant regions. This made it easier for goods, money, and ideas to circulate.

The correct choice is A because it directly connects stability with safer travel and trade. The other choices describe the opposite of what happened: routes did not all close, coins did not disappear, and farming did not stop. Peace did not remove economic activity; it supported it by creating safer conditions for markets, transport, and business. Thus, Pax Romana strengthened economic exchange across the empire.
