Final answer:
The Necessary and Proper Clause has been used to expand federal power, making the statement that it limits power false. The Proclamation of 1763 indeed was enacted in response to Pontiac's War to help stabilize frontier relations, making that statement true.
Step-by-step explanation:
The statement that 'The necessary and proper clause has had the effect of limiting the power of the national government' is false. The Necessary and Proper Clause, found in Article I, Section 8 of the Constitution, grants Congress the power to pass all laws that are essential and appropriate to execute its constitutional powers. Over time, this clause has been used to expand federal power rather than limit it, as it gives Congress the flexibility to enact laws not expressly listed in the Constitution, as long as they are related to the powers the Constitution does grant.
Regarding the Proclamation of 1763, the statement that it was enacted in part as a response to Pontiac's War is true. The Proclamation was issued by the British crown following the Seven Years' War to organize North America and stabilize relations with Native American inhabitants through regulation of trade, settlement, and land purchases on the western frontier.
