During the Industrial Revolution of the 19th century, machines took over most of the manufacturing work from men, and factories replaced craftsmen’s workshops. The event that laid the groundwork for this monumental change was the introduction of interchangeable parts, or pre-manufactured parts that were for all practical purposes identical, into the firearms industry. Interchangeable parts, popularized in America when Eli Whitney used them to assemble muskets in the first years of the 19th century, allowed relatively unskilled workers to produce large numbers of weapons quickly and at lower cost, and made repair and replacement of parts infinitely easier.

Explanation:
The Maya were native people of Mexico and Central America, while Aztec covered most of northern Mesoamerica between c.1345 and 1521 CE, whereas Inca flourished in ancient Peru between c.1400 and 1533 CE and extended across western South America.
The Maya were polytheistic but they did not have any particular God, while Aztec worship Huitzilopochtli as their main god and Inca worshiped Inti as their primary God.
The Maya created a writing system of hieroglyphics, the Aztec created the famous mask of Xuihetecuhtli that employed turquoise mosaic, and the Inca created a massive road network through mountains and rivers.
Maya builds towering temples and elaborate palaces, Aztec build their capital city Tenochtitlan on an island, while Inca constructed stone temples without using mortars yet the stone fit together so well that a knife would not fit between the stones.
The Maya used two calendars. One which was based on the solar year, while the other was a kind of sacred almanac. Maya also used a three-symbol numerical system that allowed them to record numbers into millions. While Aztec used a sacred calendar and a 365-day agricultural calendar, the Aztec writing system was based on glyphs, symbols that stand for sound or words. The Inca didn’t develop a writing system; their records were kept on bundles of knotted cords called quipus.
The Maya architects used local materials, like limestone, which they used at Palenque and Tikal, while metalwork was the most primary skill of the Aztec. Turquoise was mostly used with Aztec artists, the most common example is the decorated human skull which represents the God Tezcatlipoca. The Inca were affected by the art and techniques of Chimu civilization.
