What main issue did the Convention address regarding representation?

The Convention, formally known as the Constitutional Convention of 1787, centered around several critical issues, with a significant focus on representation and how it should be balanced between states of varying sizes. The main concern was to create a fair system that would give both populous and smaller states adequate influence in the new national government.

This led to the creation of a bicameral legislature, composed of the House of Representatives where representation would be based on a state's population, and the Senate where each state would have equal representation regardless of size. This compromise aimed to ensure that large states did not dominate the legislative process while still allowing smaller states to have a voice.

The other options, while relevant to different aspects of governance, did not address the primary issue of representation in the product of the Convention. Voter ID laws and tax revenue allocation are more contemporary issues not directly discussed during the formation of the Constitution, and selecting the President, although significant, was part of a broader discussion that included the mechanics of representation as reflected in the Electoral College.
