input question: Question: "Eight years after ranking Notre Dame as fifth highest dream school, where did the Princeton Review place Notre Dame?" Context: "In 2014 the Notre Dame student body consisted of 12,179 students, with 8,448 undergraduates, 2,138 graduate and professional and 1,593 professional (Law, M.Div., Business, M.Ed.) students. Around 2124% of students are children of alumni, and although 37% of students come from the Midwestern United States, the student body represents all 50 states and 100 countries. As of March 2007[update] The Princeton Review ranked the school as the fifth highest 'dream school' for parents to send their children. As of March 2015[update] The Princeton Review ranked Notre Dame as the ninth highest. The school has been previously criticized for its lack of diversity, and The Princeton Review ranks the university highly among schools at which "Alternative Lifestyles [are] Not an Alternative." It has also been commended by some diversity oriented publications; Hispanic Magazine in 2004 ranked the university ninth on its list of the top25 colleges for Latinos, and The Journal of Blacks in Higher Education recognized the university in 2006 for raising enrollment of African-American students. With 6,000 participants, the university's intramural sports program was named in 2004 by Sports Illustrated as the best program in the country, while in 2007 The Princeton Review named it as the top school where "Everyone Plays Intramural Sports." The annual Bookstore Basketball tournament is the largest outdoor five-on-five tournament in the world with over 700 teams participating each year, while the Notre Dame Men's Boxing Club hosts the annual Bengal Bouts tournament that raises money for the Holy Cross Missions in Bangladesh." Answer:???
output answer: ninth

Question: "Why were the new guns being used?" Context: "After the Dambusters raid in 1943 an entirely new system was developed that was required to knock down any low-flying aircraft with a single hit. The first attempt to produce such a system used a 50 mm gun, but this proved inaccurate and a new 55 mm gun replaced it. The system used a centralised control system including both search and targeting radar, which calculated the aim point for the guns after considering windage and ballistics, and then sent electrical commands to the guns, which used hydraulics to point themselves at high speeds. Operators simply fed the guns and selected the targets. This system, modern even by today's standards, was in late development when the war ended." Answer:
----
Answer: knock down any low-flying aircraft with a single hit

Q: Question: "What was a key part of the defenses?" Context: "From early 1944 until the days leading up to the invasion, Kuribayashi transformed the island into a massive network of bunkers, hidden guns, and 11 mi (18 km) of underground tunnels. The heavy American naval and air bombardment did little but drive the Japanese further underground, making their positions impervious to enemy fire. Their pillboxes and bunkers were all connected so that if one was knocked out, it could be reoccupied again. The network of bunkers and pillboxes greatly favored the defender." Answer:
A: a massive network of bunkers

Question: Question: "What pathway does the motor cortex transfer projections to the spinal chord?" Context: "The brain contains several motor areas that project directly to the spinal cord. At the lowest level are motor areas in the medulla and pons, which control stereotyped movements such as walking, breathing, or swallowing. At a higher level are areas in the midbrain, such as the red nucleus, which is responsible for coordinating movements of the arms and legs. At a higher level yet is the primary motor cortex, a strip of tissue located at the posterior edge of the frontal lobe. The primary motor cortex sends projections to the subcortical motor areas, but also sends a massive projection directly to the spinal cord, through the pyramidal tract. This direct corticospinal projection allows for precise voluntary control of the fine details of movements. Other motor-related brain areas exert secondary effects by projecting to the primary motor areas. Among the most important secondary areas are the premotor cortex, basal ganglia, and cerebellum." Answer:
Answer: pyramidal tract

[Q]: Question: "Who started the war?" Context: "With the extension of Turkish dominion into the Balkans, the strategic conquest of Constantinople became a crucial objective. The empire had managed to control nearly all former Byzantine lands surrounding the city, but in 1402 the Byzantines were temporarily relieved when the Turco-Mongol leader Timur, founder of the Timurid Empire, invaded Anatolia from the east. In the Battle of Ankara in 1402, Timur defeated the Ottoman forces and took Sultan Bayezid I as a prisoner, throwing the empire into disorder. The ensuing civil war lasted from 1402 to 1413 as Bayezid's sons fought over succession. It ended when Mehmed I emerged as the sultan and restored Ottoman power, bringing an end to the Interregnum, also known as the Fetret Devri." Answer:
****
[A]: Timur, founder of the Timurid Empire

Problem: Given the question: Question: "Over what length of time did Motorola become high in demand with increased sales following the development of their new processors?" Context: "Intel had tried unsuccessfully to push Apple to migrate the Macintosh platform to Intel chips. Apple concluded that Intel's CISC (Complex Instruction Set Computer) architecture ultimately would not be able to compete against RISC (Reduced Instruction Set Computer) processors. While the Motorola 68040 offered the same features as the Intel 80486 and could on a clock-for-clock basis significantly outperform the Intel chip, the 486 had the ability to be clocked significantly faster without suffering from overheating problems, especially the clock-doubled i486DX2 which ran the CPU logic at twice the external bus speed, giving such equipped IBM compatible systems a significant performance lead over their Macintosh equivalents. Apple's product design and engineering didn't help matters as they restricted the use of the '040 to their expensive Quadras for a time while the 486 was readily available to OEMs as well as enthusiasts who put together their own machines. In late 1991, as the higher-end Macintosh desktop lineup transitioned to the '040, Apple was unable to offer the '040 in their top-of-the-line PowerBooks until early 1994 with the PowerBook 500 series, several years after the first 486-powered IBM compatible laptops hit the market which cost Apple considerable sales. In 1993 Intel rolled out the Pentium processors as the successor to the 486, while the Motorola 68050 was never released, leaving the Macintosh platform a generation behind IBM compatibles in the latest CPU technology. In 1994, Apple abandoned Motorola CPUs for the RISC PowerPC architecture developed by the AIM alliance of Apple Computer, IBM, and Motorola. The Power Macintosh line, the first to use the new chips, proved to be highly successful, with over a million PowerPC units sold in nine months. However, in the long run, spurning Intel for the PowerPC was a mistake as the commoditization of Intel-architecture chips meant Apple couldn't compete on price against "the Dells of the world"."
