A) Constitution of Massachusetts (1780), U.S. Constitution (1789) INCORRECT The Massachusetts Constitution is a state constitution that influenced the U.S. Constitution, but it does not address surveying or the admission of new states. The U.S. Constitution, while it includes provisions for admitting new states (Article IV, Section 3), does not itself establish surveying principles. These documents are foundational for governance and individual rights, but they do not directly relate to the process of surveying land or the specific mechanisms for creating new states from territories.
B) Mayflower Compact (1620), Articles of Confederation (1781) INCORRECT The Mayflower Compact was an early agreement for self-governance among Pilgrims, but it had no provisions for land surveying or state admission. The Articles of Confederation, while it did create a framework for the national government and did pass the Land and Northwest Ordinances, is not itself a document that establishes surveying principles. The Articles were more of a governing document, and the ordinances were separate pieces of legislation passed under its authority.
C) Common Sense (1776), Declaration of Independence (1776) INCORRECT Common Sense is a political pamphlet by Thomas Paine advocating for independence, and the Declaration of Independence announced the colonies' separation from Britain. Neither document deals with surveying land or the process of admitting new states. They are philosophical and political statements of rights and grievances, not practical guides for territorial expansion.
D) Land Ordinance (1785), Northwest Ordinance (1787) CORRECT The Land Ordinance of 1785 established a systematic method for surveying and dividing western lands into townships and sections, which was essential for selling and settling the territory. The Northwest Ordinance of 1787 created a government for the Northwest Territory and outlined a clear process for admitting new states to the Union, ensuring they would have equal status with the original states. Together, these ordinances provided the legal and practical framework for the orderly expansion of the United States, making them the correct answer.
