The two most notable achievements of the Maya (although an argument could be made that a few were accomplished) are B and C.
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. You may remember the fuss about the Mayan calendar predicting the end of the world in December of 2012, because this is the time up to which that they had calculated dates and astronomical events for. Luckily, this didn't happen until 2016 (just kidding).

1. The biography and the autobiography have lot of things in common, but they also have few differences. The biggest and most important difference between the two is that the biography is written for someone by someone else, while the autobiography is written by person himself/herself it is about. This leads us to say that the biography is taking away the personal opinion and person expressions of the person whose life is described, as it only offers the perspective from the other people, or a single person.
2. The biography and the autobiography are of great help for the historians. The biography offers the view of a particular person for the person in question, be it the action that person has done, the physical appearance, the character etc. The autobiography, on the other hand, gives clues about how the person in question has viewed himself/herself, and how that person was seeing the world and their own actions and behavior. Both combined, give a nice perspective from two sides, which gives clues about the real historical events.
