The FALSE statement when comparing the political systems of the United States and Great Britain is:
Both countries contain three branches of government with equal amounts of power.
In the United States, the government is based on a system of checks and balances among the three branches (executive, legislative, and judicial), each having distinct powers. In contrast, Great Britain has a parliamentary system where the executive branch (the Prime Minister and the Cabinet) is derived from the legislative branch, leading to a different distribution of power and not equal amounts among the branches.
