A major objective of both annapolis convention and the philadelphia convention was to?

(A) determine how the states should be represented in congress. I am doing that HW sheet now XD

To write the Constitution in secret.

For delegates from the 13 states to gather up and help revise the articles of confederation which led to the writing of the constititution.

See: http://college.hmco.com/history/readerscomp/rcah/html/ah_068400_philadelphia.htm Short answer, writing the United States Constitution is the major event. Mark Coomes Denton TX

The Annapolis Convention was held in the city Annapolis, MD therefore they called it the Annapolis Convention.
