Correct Answer: incas.
the correct answer is the incas. the incas were a group of indigenous people who lived in south america and occupied a vast territory that extended from northern ecuador all the way down to chile. this area is known for its challenging geography, featuring everything from arid coastal deserts to high mountain ranges in the andes.
one of the most remarkable achievements of the incas was their construction of an extensive and sophisticated network of roads. this network, often referred to as the inca road system, spanned approximately 40,000 kilometers. it was engineered to facilitate the efficient movement of armies, traders, and messengers across the empire. these roads also played a crucial role in consolidating the inca's control over their vast territory, allowing for effective communication, transportation, and administrative control.
in addition to their engineering prowess, the incas were also adept farmers and herders. they developed agricultural techniques suitable for their environment, such as terrace farming, which maximized arable land area in mountainous regions and improved soil fertility and water retention. they cultivated a variety of crops, including potatoes, maize, and quinoa, which remain staples in south american diets today.
the incas also raised llamas and alpacas for meat, wool, and as beasts of burden. the ability to transport goods and people efficiently, combined with their agricultural and herding skills, were key to the inca empire's economic stability and growth.
overall, the incas' advanced road systems, sophisticated agricultural practices, and effective administrative strategies were instrumental in creating one of the most powerful empires in the pre-columbian americas. their legacy continues to be a subject of admiration and study in both historical and archaeological fields.
