I don't know how to phrase this one concisely, so I'll just take a stab at it: does each player get one opportunity to declare each type of attack, or do they alternate opportunities to declare until either they've taken both or both passed?
Example
Player A and Player B go to conflict phase. Player A is first player. Which of the following is true:
Player A passes first option to attack. Player B attacks political. Player A attacks military. Player B attacks military. Player A attacks political.
OR
Player A passes first option to attack. Player B attacks political. Player A cannot now declare an attack since they passed once. Player B attacks military.
