Why might it sometimes be difficult for a president to rely on the advice of cabinet members? a) cabinet members may not have the right background for the cabinet position. b) most cabinet members tend to only give the president advice that the president wants to hear. c) meetings only take place once a week and presidents need to receive important information in a more timely manner. d) a president may appoint someone to a cabinet position for political reasons instead, not based on expertise in the field.
