Problem: Strasbourg:

The German Renaissance has bequeathed the city some noteworthy buildings (especially the current Chambre de commerce et d'industrie, former town hall, on Place Gutenberg), as did the French Baroque and Classicism with several hôtels particuliers (i.e. palaces), among which the Palais Rohan (1742, now housing three museums) is the most spectacular. Other buildings of its kind are the "Hôtel de Hanau" (1736, now the city hall), the Hôtel de Klinglin (1736, now residence of the préfet), the Hôtel des Deux-Ponts (1755, now residence of the military governor), the Hôtel d'Andlau-Klinglin (1725, now seat of the administration of the Port autonome de Strasbourg) etc. The largest baroque building of Strasbourg though is the 150 m (490 ft) long 1720s main building of the Hôpital civil. As for French Neo-classicism, it is the Opera House on Place Broglie that most prestigiously represents this style.

Problem: John Kerry:

Kerry said on September 9 in response to a reporter's question about whether Syrian President Bashar al-Assad could avert a military strike: "He could turn over every single bit of his chemical weapons to the international community in the next week. Turn it over, all of it, without delay, and allow a full and total accounting for that. But he isn't about to do it, and it can't be done, obviously." This unscripted remark initiated a process that would lead to Syria agreeing to relinquish and destroy its chemical weapons arsenal, as Russia treated Kerry's statement as a serious proposal. Russian Foreign Minister Sergey Lavrov said Russia would work "immediately" to convince Syria relinquish and destroy its large chemical weapons arsenal. Syria quickly welcomed this proposal and on September 14, the UN formally accepted Syria's application to join the convention banning chemical weapons, and separately, the U.S. and Russia agreed on a plan to eliminate Syria's chemical weapons by the middle of 2014. On September 28, the UN Security Council passed a resolution ordering the destruction of Syria's chemical weapons and condemning the August 21 Ghouta attack.

When did the UN Security Council order Syria's chemical weapons be destroyed?

A: September 28
