Which is not an achievement of Mayan civilization?

A.

towering stone monuments called stelae

B.

a system of interconnected mountain roads and bridges

C.

advanced knowledge of mathematics

D.

a system of hieroglyph writing

I would say the correct answer is B. a system of interconnected mountain roads and bridges.

A should be true as they did make these monuments called stelae. C is correct because their knowledge of math was far superior than any other nation. D is also correct because the Maya did use hieroglyphs to write. I would say that B doesn't belong here because roads were Roman inventions.
