Answers to A Presidential Puzzler above:
1) Édith Cresson served as France's prime minister from 1991 to 1992. Her tenure "plumbed new depths of unpopularity" and was marred by "attacks on her gender." Eventually President François Mitterand accepted her resignation. Her subsequent service as a member of the European Commission in charge of science and research was marred by a corruption scandal: it ended last year with the European Court of Justice finding that she had breached her obligations as a European Commissioner by having her private dentist appointed to a staff position.
2) a) Switzerland. Micheline Calmy-Rey (right) became President of the Swiss Federation in January 2007. Calmy-Rey, who will hold the position through this calendar year, also serves as head of the Federal Department of Foreign Affairs.
