Problem: Extract the answer to the question from the following context. Question: What was an issue with the discs? Context: Similar to the CD versus LP sound quality debates common in the audiophile community, some videophiles argue that LaserDisc maintains a "smoother", more "film-like", natural image while DVD still looks slightly more artificial. Early DVD demo discs often had compression or encoding problems, lending additional support to such claims at the time. However, the video signal-to-noise ratio and bandwidth of LaserDisc are substantially less than that of DVDs, making DVDs appear sharper and clearer to most viewers.

A: DVD still looks slightly more artificial


Problem: Extract the answer to the question from the following context. Question: Which is the only philosophy that influence the samurai culture, but this influence is not explained by the text? Context: The philosophies of Buddhism and Zen, and to a lesser extent Confucianism and Shinto, influenced the samurai culture. Zen meditation became an important teaching due to it offering a process to calm one's mind. The Buddhist concept of reincarnation and rebirth led samurai to abandon torture and needless killing, while some samurai even gave up violence altogether and became Buddhist monks after realizing how fruitless their killings were. Some were killed as they came to terms with these realizations in the battlefield. The most defining role that Confucianism played in samurai philosophy was to stress the importance of the lord-retainer relationship—the loyalty that a samurai was required to show his lord.

A: Shinto


Problem: Extract the answer to the question from the following context. Question: Have a larger percentage of the population completed non-mandatory upper secondary education or additional higher education? Context: In Bern, about 50,418 or (39.2%) of the population have completed non-mandatory upper secondary education, and 24,311 or (18.9%) have completed additional higher education (either university or a Fachhochschule). Of the 24,311 who completed tertiary schooling, 51.6% were Swiss men, 33.0% were Swiss women, 8.9% were non-Swiss men and 6.5% were non-Swiss women.

A: non-mandatory upper secondary education


Problem: Extract the answer to the question from the following context. Question: What's the disease mentioned that a vaccine was created for Context: Early progress toward the development of vaccines occurred throughout this period, primarily in the form of academic and government-funded basic research directed toward the identification of the pathogens responsible for common communicable diseases. In 1885 Louis Pasteur and Pierre Paul Émile Roux created the first rabies vaccine. The first diphtheria vaccines were produced in 1914 from a mixture of diphtheria toxin and antitoxin (produced from the serum of an inoculated animal), but the safety of the inoculation was marginal and it was not widely used. The United States recorded 206,000 cases of diphtheria in 1921 resulting in 15,520 deaths. In 1923 parallel efforts by Gaston Ramon at the Pasteur Institute and Alexander Glenny at the Wellcome Research Laboratories (later part of GlaxoSmithKline) led to the discovery that a safer vaccine could be produced by treating diphtheria toxin with formaldehyde. In 1944, Maurice Hilleman of Squibb Pharmaceuticals developed the first vaccine against Japanese encephelitis. Hilleman would later move to Merck where he would play a key role in the development of vaccines against measles, mumps, chickenpox, rubella, hepatitis A, hepatitis B, and meningitis.
