24. Based on the excerpt, which change was a result of the National Security Act of 1947?
Answer: D
The Department of the Navy became part of the Department of Defense.
The National Security Act of 1947 resulted in the reorganization of military and intelligence functions, which included integrating the Department of the Navy into the newly created Department of Defense.
A) The Central Intelligence Agency replaced the War Department.
This statement is incorrect as the Central Intelligence Agency (CIA) was established by the National Security Act of 1947, but it did not replace the War Department. The War Department was reorganized and transformed into the Department of the Army, which continued to exist alongside the CIA.
B) The National Security Council gained control over the Department of Defense.
This option is also incorrect. While the National Security Council (NSC) was created to advise the President on security matters, it does not control the Department of Defense. The NSC functions independently to coordinate the national security policies of the executive branch.
C) The Department of Homeland Security replaced the War Department.
This statement is false. The Department of Homeland Security (DHS) was established much later, in 2003, and did not replace the War Department. The War Department was reorganized into the Department of the Army as part of the changes made in 1947.
D) The Department of the Navy became part of the Department of Defense.
This statement is correct. The National Security Act of 1947 led to the creation of the Department of Defense, which consolidated the military services, including the Department of the Navy, under a unified command structure.
Conclusion
The correct answer is D, as it accurately reflects the structural changes made by the National Security Act of 1947, which unified military services under the Department of Defense. Other options either misstate the outcomes of the Act or refer to entities and changes that occurred outside the scope of the 1947 reorganization.
