Problem: Given the question: Question: "Which diphtheria vaccination formula was safer, the mixture of diphtheria toxin and antitoxin or treating diphtheria toxin with formaldehyde?" 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 Emile 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." Answer:

formaldehyde

Problem: Given the question: Question: "What did the crew do?" Context: "Nevertheless, it was radar that proved to be critical weapon in the night battles over Britain from this point onward. Dowding had introduced the concept of airborne radar and encouraged its usage. Eventually it would become a success. On the night of 22/23 July 1940, Flying Officer Cyril Ashfield (pilot), Pilot Officer Geoffrey Morris (Observer) and Flight Sergeant Reginald Leyland (Air Intercept radar operator) of the Fighter Interception Unit became the first pilot and crew to intercept and destroy an enemy aircraft using onboard radar to guide them to a visual interception, when their AI night fighter brought down a Do 17 off Sussex. On 19 November 1940 the famous RAF night fighter ace John Cunningham shot down a Ju 88 bomber using airborne radar, just as Dowding had predicted." Answer:

Problem: Given the question: Question: "Who lived by the teachings of Mahayana?" Context: "There is no evidence that Mahayana ever referred to a separate formal school or sect of Buddhism, but rather that it existed as a certain set of ideals, and later doctrines, for bodhisattvas. Initially it was known as Bodhisattvayana (the "Vehicle of the Bodhisattvas"). Paul Williams has also noted that the Mahayana never had nor ever attempted to have a separate Vinaya or ordination lineage from the early schools of Buddhism, and therefore each bhiksu or bhiksuni adhering to the Mahayana formally belonged to an early school. This continues today with the Dharmaguptaka ordination lineage in East Asia, and the Mulasarvastivada ordination lineage in Tibetan Buddhism. Therefore Mahayana was never a separate rival sect of the early schools. From Chinese monks visiting India, we now know that both Mahayana and non-Mahayana monks in India often lived in the same monasteries side by side." Answer:

The answer is:
bodhisattvas
