Although there are no options attached, we can say the following.

The subject of the resolution that James Madison proposed to the United States Congress of confederation was the creation of a bicameral Congress in order to have a legislative branch divided into two chambers: one chamber would be the House of Representatives or the lower chamber, and the other would be the Senate or the upper chamber.
