Read this excerpt from George Washington's Farewell Address. Then answer the questions that follow. To the efficacy and permanency of your Union, a government for the whole is indispensable. No alliance, however
strict, between the parts can be an adequate substitute; they must inevitably experience the infractions and
interruptions which all alliances in all times have experienced. Sensible of this momentous truth, you have improved
upon your first essay, by the adoption of a constitution of government better calculated than your former for an
intimate union, and for the efficacious management of your common concerns. This government, the offspring of our
own choice, uninfluenced and unawed, adopted upon full investigation and mature deliberation, completely free in its
principles, in the distribution of its powers, uniting security with energy, and containing within itself a provision for its
own amendment, has a just claim to your confidence and your support.
