The correct answer is B) people who used simple tools to carve from large stones.
Olmecs would have influenced people who used simple tools to carve from large stones.
The Olmecs were great engineers in Mesoamerica. They were a civilization that lived on the coast of the Gulf of Mexico, in what today is the territory of the Mexican's states of Tabasco and Veracruz. They built great cities like La Venta and San Lorenzo. It was in the city of San Lorenzo that they carved out massive stones and put them side by side to construct an aqueduct. That is why Olmecs would have influenced people who used simple tools to carve from large stones.
The other options of the question were a) people who made flat terraces, c) people who navigated the oceans, and d) people who worshiped a single God by sacrificing prisoners of war.
