Which group does the president most rely upon for day-to-day advice?

the cabinet

the executive office of the president

the congressional budget office

state governors

Correct  The Executive Office of the President

The Executive Office of the President of the United States (EOP) is what we call the various agencies that assist the President in carrying out his role as Chief Executive of the nation.  The White House Office (the staff that works at the White House) is part of the Executive Office of the President (EOP), but so also are agencies such as the National Security Council and the Office of Management and Budget.   The White House staff and National Security Council are very much people the president will rely on in the day to day operation of presidential business.

Britain and France had to abandon their plans to send military aid to the Confederates.

By using the Proclamation as an instrument to turn the war into a crusade against slavery (which it hadn't been), Lincoln made it politically impossible for free nations abroad to help the South.

Both Britain and France had abolished slavery many years earlier, and could not be seen to fight for the cause of the slave-owners.Hope this helps:)
