Article: Aside from the 20th century addition of the Bois de Boulogne, Bois de Vincennes and Paris heliport, Paris' administrative limits have remained unchanged since 1860. The Seine departement had been governing Paris and its suburbs since its creation in 1790, but the rising suburban population had made it difficult to govern as a unique entity. This problem was 'resolved' when its parent "District de la region parisienne" (Paris region) was reorganised into several new departments from 1968: Paris became a department in itself, and the administration of its suburbs was divided between the three departments surrounding it. The Paris region was renamed "Ile-de-France" in 1977, but the "Paris region" name is still commonly used today. Paris was reunited with its suburbs on January 1, 2016 when the Metropole du Grand Paris came into existence.

Question: What are they only two additions to Paris' administrative limits since 1860?
Ans: Bois de Boulogne, Bois de Vincennes

Article: On 10 October 2009, Armenia and Turkey signed protocols on normalisation of relationships, which set a timetable for restoring diplomatic ties and reopening their joint border. The ratification of those had to be made in the national parliaments. In Armenia it passed through the required by legislation approval of the Constitutional Court and was sent to the parliament for the final ratification. The President had made multiple public announcements, both in Armenia and abroad, that as the leader of the political majority of Armenia he assured the ratification of the protocols if Turkey also ratified them. Despite this, the process stopped, as Turkey continuously added more preconditions to its ratification and also "delayed it beyond any reasonable time-period".

Question: When did Armenia and Turkey initiate an attempt to reopen their border?
Ans:
10 October 2009
