Please help me I have under a week left to finish school

For each of the five civilizations you studied in this
unit (Han, Gupta, Maya, Aztec, Inca), identify one
development that you think is the most significant
for each civilization. Then rank those five
developments in importance from 1 to 5 (1 most
important, 5 least important).
While your opinion may play a role in your choice,
your rankings should reflect sound reasoning. So,
you should base your rankings on specific
qualities such as the short- and long-term impact
that each development had on other civilizations
at the time or the degree of technological
advancement and creativity that it demonstrates
maximum character
Be prepared to defend your choices and rankings.
Again, your aim is to supportable
rankings. Discuss and question the rankings of
your peers as well.
