Problem: Please answer a question about the following article about Hard rock:
While these few hard rock bands managed to maintain success and popularity in the early part of the decade, alternative forms of hard rock achieved mainstream success in the form of grunge in the US and Britpop in the UK. This was particularly evident after the success of Nirvana's Nevermind (1991), which combined elements of hardcore punk and heavy metal into a "dirty" sound that made use of heavy guitar distortion, fuzz and feedback, along with darker lyrical themes than their "hair band" predecessors. Although most grunge bands had a sound that sharply contrasted mainstream hard rock, several, including Pearl Jam, Alice in Chains, Mother Love Bone and Soundgarden, were more strongly influenced by 1970s and 1980s rock and metal, while Stone Temple Pilots managed to turn alternative rock into a form of stadium rock. However, all grunge bands shunned the macho, anthemic and fashion-focused aesthetics particularly associated with glam metal. In the UK, Oasis were unusual among the Britpop bands of the mid-1990s in incorporating a hard rock sound.
What was the title of Nirvana's 1991 album?
A: Nevermind

Problem: Please answer a question about the following article about Pharmaceutical industry:
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.
Who developed the first encephalitis vaccine?
A: Maurice Hilleman
