Example Input: The interface of Windows 8 has been the subject of mixed reaction. Bright wrote that its system of hot corners and edge swiping "wasn't very obvious" due to the lack of instructions provided by the operating system on the functions accessed through the user interface, even by the video tutorial added on the RTM release (which only instructed users to point at corners of the screen or swipe from its sides). Despite this "stumbling block", Bright said that Windows 8's interface worked well in some places, but began to feel incoherent when switching between the "Metro" and desktop environments, sometimes through inconsistent means. Tom Warren of The Verge wrote that the new interface was "as stunning as it is surprising", contributing to an "incredibly personal" experience once it is customized by the user, but had a steep learning curve, and was awkward to use with a keyboard and mouse. He noted that while forcing all users to use the new touch-oriented interface was a risky move for Microsoft as a whole, it was necessary in order to push development of apps for the Windows Store. Others, such as Adrian Kingsley-Hughes from ZDNet, considered the interface to be "clumsy and impractical" due to its inconsistent design (going as far as considering it "two operating systems unceremoniously bolted together"), and concluded that "Windows 8 wasn't born out of a need or demand; it was born out of a desire on Microsoft's part to exert its will on the PC industry and decide to shape it in a direction—touch and tablets -- that allows it to compete against, and remain relevant in the face of Apple's iPad."
Example Output: What makes the Windows 8 interface difficult to use?

Example Input: 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.
Example Output: When was the Philippine-American War fought?

Example Input: In January 1880, two of Tesla's uncles put together enough money to help him leave Gospić for Prague where he was to study. Unfortunately, he arrived too late to enroll at Charles-Ferdinand University; he never studied Greek, a required subject; and he was illiterate in Czech, another required subject. Tesla did, however, attend lectures at the university, although, as an auditor, he did not receive grades for the courses.
Example Output:
What city did Tesla move to in 1880?
