Passage: The building was sold in 1549 by Buonaccorso Pitti, a descendant of Luca Pitti, to Eleonora di Toledo.  Raised at the luxurious court of Naples, Eleonora was the wife of Cosimo I de' Medici of Tuscany, later the Grand Duke.  On moving into the palace, Cosimo had Vasari enlarge the structure to fit his tastes; the palace was more than doubled by the addition of a new block along the rear.  Vasari also built the Vasari Corridor, an above-ground walkway from Cosimo's old palace and the seat of government, the Palazzo Vecchio, through the Uffizi, above the Ponte Vecchio to the Palazzo Pitti. This enabled the Grand Duke and his family to move easily and safely from their official residence to the Palazzo Pitti. Initially the Palazzo Pitti was used mostly for lodging official guests and for occasional functions of the court, while the Medicis' principal residence remained the Palazzo Vecchio. It was not until the reign of Eleonora's son Francesco I and his wife Johanna of Austria that the palazzo was occupied on a permanent basis and became home to the Medicis' art collection.Land on the Boboli hill at the rear of the palazzo was acquired in order to create a large formal park and gardens, today known as the Boboli Gardens. The landscape architect employed for this was the Medici court artist Niccolò Tribolo, who died the following year; he was quickly succeeded by Bartolommeo Ammanati. The original design of the gardens centred on an amphitheatre, behind the corps de logis of the palazzo. The first play recorded as performed there was Andria by Terence in 1476. It was followed by many classically inspired plays of Florentine playwrights such as Giovan Battista Cini. Performed for the amusement of the cultivated Medici court, they featured elaborate sets designed by the court architect Baldassarre Lanci. 
Question: What is the first name of the Grand Duke whose family was enabled to move easily and safely from their official residence?
Cosimo.

Passage: From the colonizers' perspective, Carabane's position at the mouth of the river was an undeniable asset. In the 20th and 21st centuries, in terms of trade and tourism issues, this location is more of a disadvantage because it effectively separates the island from the rest of the country.
While a direct route by sea has not been available since the sinking of the Joola, the traveller from Dakar may use various other means of transportation in order to arrive in Basse Casamance. Some national roads connect to Ziguinchor, down the N1 to Kaolack. The N4 and N5 roads cross the Gambia (both the country and the river), the former running through Nioro du Rip to Farafenni, and the latter crossing the river to Banjul. The two roads merge in Bignona before descending to Ziguinchor. However, traffic is forbidden on both roads between 7 p.m. and 10 a.m., and the routes are subject to frequent accidents and constant demining operations. Alternatively, it is possible to travel by plane to the airport in Ziguinchor or Cap Skirring, or to travel by boat to one of these locations. Reaching Carabane from either town is relatively straightforward.By boat, the distance between Dakar and Carabane is 265 kilometres (143 nmi), although Ziguinchor is only 48 kilometres (30 mi) away. Before the launch of the Joola, other boats, mostly well-worn ones, made the connection: first Cap Skirring, then the Casamance Express, and then Island Karabane. In January 1991, a brand new ferry went into operation. Like its predecessors, it connected Dakar to Ziguinchor, stopping near Carabane where canoes could reach the island. On September 26, 2002, 180 extra passengers boarded the already overloaded ship at this stop, and a few hours later, the Joola sank. For security reasons, the Joola's successor, the Wilis, stopped calling at Carabane, to the great displeasure of the inhabitants. Tourists became rare after that, and from time to time, inhabitants of the island found it necessary to move to Dakar or Ziguinchor. Significant modifications to the MV Aline Sitoe Diatta, which replaced the Wilis in March 2008, were considered to allow it to stop safely at the island, and the construction of a berth was announced. Souleymane Ndéné Ndiaye, who later became Prime Minister of Senegal, laid the first stone of the berth in July 2008, and the entire construction project was financed by the Senegalese government at an estimated cost of 12 billion West African CFA francs. On April 26, 2014, the MV Aline Sitoe Diatta stopped at the Carabane berth for the first time, improving transportation for locals and tourists. As of 2015, the ferry stops at Carabane four times each week in the middle of its trips between Dakar and Ziguinchor. 
Question: What is the name of the ferry that, since 2015, stops at Carabane four times each week in the middle of its trips between Dakar and Ziguinchor?
MV Aline Sitoe Diatta.

Passage: Britain's declaration of war against Nazi Germany in September 1939 included the Crown colonies and India but did not automatically commit the Dominions of Australia, Canada, New Zealand, Newfoundland and South Africa. All soon declared war on Germany, but Ireland chose to remain legally neutral throughout the war.After the Fall of France in June 1940, Britain and the empire stood alone against Germany, until the German invasion of Greece on 7 April 1941. British Prime Minister Winston Churchill successfully lobbied President Franklin D. Roosevelt for military aid from the United States, but Roosevelt was not yet ready to ask Congress to commit the country to war. In August 1941, Churchill and Roosevelt met and signed the Atlantic Charter, which included the statement that "the rights of all peoples to choose the form of government under which they live" should be respected. This wording was ambiguous as to whether it referred to European countries invaded by Germany and Italy, or the peoples colonised by European nations, and would later be interpreted differently by the British, Americans, and nationalist movements.In December 1941, Japan launched, in quick succession, attacks on British Malaya, the United States naval base at Pearl Harbor, and Hong Kong. Churchill's reaction to the entry of the United States into the war was that Britain was now assured of victory and the future of the empire was safe, but the manner in which British forces were rapidly defeated in the Far East irreversibly harmed Britain's standing and prestige as an imperial power. Most damaging of all was the Fall of Singapore, which had previously been hailed as an impregnable fortress and the eastern equivalent of Gibraltar. The realisation that Britain could not defend its entire empire pushed Australia and New Zealand, which now appeared threatened by Japanese forces, into closer ties with the United States. This resulted in the 1951 ANZUS Pact between Australia, New Zealand and the United States of America. 
Question: What location was the city that was seen as impregnable fortress considered to be the eastern equivalent of?

Gibraltar.
