Answer:
Formation of a bicameral legislature was the most significant contribution made by John Adams to the U.S. Constitution
Step-by-step explanation:
John Adams proposed Bicameral legislature. It is desirable in a system of democracy. It avoids harsh and hasty legislation. Bicameral legislature means a parliament or a congress which has two houses and upper house and a lower house.
He proclaimed that a bicameral legislature would act as a system of supervisory and regulatory authority and does not favor any single segment or branch of the government becoming authoritative.
He believed a single assembly or council would become too ambitious and after a time it starts to feel that it’s an element that runs perpetually.
