The quote that best explains the differences between each congressional chamber's approach to the legislative process is:
"Each House may determine the Rules of its Proceedings."
This quote indicates that each chamber of Congress (the House of Representatives and the Senate) has the authority to establish its own rules and procedures for how it conducts its business, which leads to differences in their legislative approaches. The House typically operates under more structured and hierarchical rules, while the Senate often allows for more open debate and individual member influence.
