Which two of the following are notable achievements of the maya? pick two
-developing an extensive road system
-creating a hieroglyphic writing system
-inventing an accurate calendar system
-establishing a unified tribute empire
-creating advanced methods of irrigation

The two most notable achievements of the Maya (although an argument could be made that a few were accomplished) are creating a hieroglyphic writing system, and, inventing an accurate calendar system.

The Maya are considered the only precolonial American civilization to develop a complete writing system, which means they had a written language that could communicate any spoken idea. 

The Maya also developed an extremely accurate calendar, based on advanced knowledge of astronomy.
