Final answer:
George Washington did not refuse to run again after serving two terms. He voluntarily chose not to seek a third term, setting a precedent for limiting presidential terms and avoiding potential abuses of power.
Step-by-step explanation:
The correct answer is a. He refused to run again after serving two terms.
One of the ways George Washington expanded the power of the presidency was by appointing the heads of various federal departments as his own advisors (option b). This created the concept of the president having a cabinet or group of advisors to aid in decision-making.
Additionally, Washington worked with the Senate to draft treaties with foreign countries (option c). This demonstrated the president's ability to negotiate and shape foreign policy on behalf of the nation.
Furthermore, Washington submitted his neutrality proclamation to the Senate for approval (option d). This proclamation set a precedent for the president to take a stance on international conflicts and assert the executive branch's authority in matters of foreign affairs.
However, George Washington did not refuse to run again after serving two terms (option a). He voluntarily chose not to seek a third term, setting a precedent for future presidents to follow. This action solidified the idea of limiting presidential terms and avoiding potential abuses of power.
