You need to clarify the inventions being referenced.

Rope bridges: Enabled the Inca to traverse vast distances and maintain communication with neighboring groups. The Inca excelled in utilizing fiber to address their challenges, and one of their prominent innovations is the rope bridge. They constructed remarkably lengthy structures from ichu grass, fashioned into substantial bundles to form bridges that played a critical role in the Inca road network. Chinampas: Allowed the Aztec to enhance agricultural efficiency. Chinampas refers to a type of farming that utilized small, rectangular plots of fertile land to grow crops on the shallow lake beds in Mexico. Often called "floating gardens," this agricultural method was not originally developed by the Aztecs but was first employed by this civilization for large-scale farming. Pyramid at Chichen Itza: Enabled the Maya to observe celestial events like eclipses without any assistance. Known as the Pyramid of Kukulcan, or The Castle in Spanish, this structure has various functions, including astronomical observations. It permitted the Mayans to witness celestial phenomena without additional equipment and also acted as a solar calendar (each of the pyramid's four sides consists of 91 steps, and with the top platform counted, they total to 365, which corresponds to the number of days in their calendar).
