Problem: Windows 8:

An upgrade to Windows 8 known as Windows 8.1 was officially announced by Microsoft on May 14, 2013. Following a presentation devoted to the upgrade at Build 2013, a public beta version of the upgrade was released on June 26, 2013. Windows 8.1 was released to OEM hardware partners on August 27, 2013, and released publicly as a free download through Windows Store on October 17, 2013. Volume license customers and subscribers to MSDN Plus and TechNet Plus were initially unable to obtain the RTM version upon its release; a spokesperson said the policy was changed to allow Microsoft to work with OEMs "to ensure a quality experience at general availability." However, after criticism, Microsoft reversed its decision and released the RTM build on MSDN and TechNet on September 9, 2013.

Problem: The 1960s were less successful for the club, with Real Madrid monopolising La Liga. The completion of the Camp Nou, finished in 1957, meant the club had little money to spend on new players. The 1960s saw the emergence of Josep Maria Fusté and Carles Rexach, and the club won the Copa del Generalísimo in 1963 and the Fairs Cup in 1966. Barcelona restored some pride by beating Real Madrid 1–0 in the 1968 Copa del Generalísimo final at the Bernabéu in front of Franco, with coach Salvador Artigas, a former republican pilot in the civil war. With the end of Franco's dictatorship in 1974, the club changed its official name back to Futbol Club Barcelona and reverted the crest to its original design, including the original letters once again.
With Franco's dictatorship over, to what did Barcelona change their name ?

Answer: Futbol Club Barcelona

The port was the point of departure for the Pilgrim Fathers aboard Mayflower in 1620. In 1912, the RMS Titanic sailed from Southampton. Four in five of the crew on board the vessel were Sotonians, with about a third of those who perished in the tragedy hailing from the city. Southampton was subsequently the home port for the transatlantic passenger services operated by Cunard with their Blue Riband liner RMS Queen Mary and her running mate RMS Queen Elizabeth. In 1938, Southampton docks also became home to the flying boats of Imperial Airways. Southampton Container Terminals first opened in 1968 and has continued to expand.
What famous ship left Southampton's port carrying the Pilgrim Fathers?
A: Mayflower

Question: The Philippine–American War (1899–1902) was an armed conflict between a group of Filipino revolutionaries and the American forces following the ceding of the Philippines to the United States after the defeat of Spanish forces in the Battle of Manila. The Army sent in 100,000 soldiers (mostly from the National Guard) under General Elwell Otis. Defeated in the field and losing its capital in March 1899, the poorly armed and poorly led rebels broke into armed bands. The insurgency collapsed in March 1901 when the leader Emilio Aguinaldo was captured by General Frederick Funston and his Macabebe allies. Casualties included 1,037 Americans killed in action and 3,340 who died from disease; 20,000 rebels were killed.

By the time of the Uruk period (c. 4100–2900 BC calibrated), the volume of trade goods transported along the canals and rivers of southern Mesopotamia facilitated the rise of many large, stratified, temple-centered cities (with populations of over 10,000 people) where centralized administrations employed specialized workers. It is fairly certain that it was during the Uruk period that Sumerian cities began to make use of slave labor captured from the hill country, and there is ample evidence for captured slaves as workers in the earliest texts. Artifacts, and even colonies of this Uruk civilization have been found over a wide area—from the Taurus Mountains in Turkey, to the Mediterranean Sea in the west, and as far east as central Iran.
How many people lived in the cities?
A:
over 10,000
