In the USA, each branch of government has powers that have been defined as theirs by the Constitution. However, there is a notion of other powers that are not explicitly mentioned in it. In the case of Congress, such implied powers are deemed to be “necessary and proper”, that is to say, that it is understood that although they are not granted explicitly by the Constitution, they are logically and reasonably required to exercise those powers which are explicitly granted by the Constitution. Since the powers of coining money, acquiring territory and declaring war are explicitly granted by the Constitution to the federal government, the correct answer for this question would be building highway systems, which is an implied power (that also happens to be a concurrent power (a power that is exercised both by the federal and the state governments).

The Tet Offensive was considered a turning point in the war because in the Tet Offensive, the VietCong launched a massive counterattack all over allied posts, starting from the North down. It was all planned out and launched within minutes of each other. The U.S. Embassy was infiltrated for about 1-2 days, and when the media reported it and captured images of American soldiers dying, many American people knew that the war was far from over and demanded U.S. troops to withdraw from the war. The media leakage made the U.S. Government look bad because they were lying to the people about the war. After that, the U.S. makes a temporary deal with the VietCong, leader was Ho Chi Minh, and the U.S. slowly withdraws. After the U.S. fully withdrew, the North resumed their attacks, and the South couldn't defend themselves without a strong leader, because Ngo Dinh Diem (leader of South Vietnam) was assassinated and the U.S. were no longer in the war. South Vietnam fell to Communism on April 30, 1975.
