Problem: 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

Problem: The city hosts numerous theatres and production houses, including the Yale Repertory Theatre, the Long Wharf Theatre, and the Shubert Theatre. There is also theatre activity from the Yale School of Drama, which works through the Yale University Theatre and the student-run Yale Cabaret. Southern Connecticut State University hosts the Lyman Center for the Performing Arts. The shuttered Palace Theatre (opposite the Shubert Theatre) is being renovated and will reopen as the College Street Music Hall in May, 2015. Smaller theatres include the Little Theater on Lincoln Street. Cooperative Arts and Humanities High School also boasts a state-of-the-art theatre on College Street. The theatre is used for student productions as well as the home to weekly services to a local non-denominational church, the City Church New Haven.
Yale also has a theater managed by its' own student, then name?

Answer: Yale Cabaret.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Ethernet standards require electrical isolation between the networked device (computer, phone, etc.) and the network cable up to 1500 V AC or 2250 V DC for 60 seconds. USB has no such requirement as it was designed for peripherals closely associated with a host computer, and in fact it connects the peripheral and host grounds. This gives Ethernet a significant safety advantage over USB with peripherals such as cable and DSL modems connected to external wiring that can assume hazardous voltages under certain fault conditions.
Ethernet standards require what?
A: isolation between the networked device (computer, phone, etc.) and the network cable up to 1500 V AC or 2250 V DC for 60 seconds

Context and question: In the late 14th century, the Songhai gradually gained independence from the Mali Empire and expanded, ultimately subsuming the entire eastern portion of the Mali Empire. The Songhai Empire's eventual collapse was largely the result of a Moroccan invasion in 1591, under the command of Judar Pasha. The fall of the Songhai Empire marked the end of the region's role as a trading crossroads. Following the establishment of sea routes by the European powers, the trans-Saharan trade routes lost significance.
What cause sea routes to lose significance?
Answer: unanswerable

Question: Unicode has the explicit aim of transcending the limitations of traditional character encodings, such as those defined by the ISO 8859 standard, which find wide usage in various countries of the world but remain largely incompatible with each other. Many traditional character encodings share a common problem in that they allow bilingual computer processing (usually using Latin characters and the local script), but not multilingual computer processing (computer processing of arbitrary scripts mixed with each other).
Is there an answer to this question: What is multilingual computer processing?

Answer: (computer processing of arbitrary scripts mixed with each other

In the late 1980s, key breakthroughs in GaN epitaxial growth and p-type doping ushered in the modern era of GaN-based optoelectronic devices. Building upon this foundation, Dr. Moustakas at Boston University patented a method for producing high-brightness blue LEDs using a new two-step process. Two years later, in 1993, high-brightness blue LEDs were demonstrated again by Shuji Nakamura of Nichia Corporation using a gallium nitride growth process similar to Dr. Moustakas's. Both Dr. Moustakas and Mr. Nakamura were issued separate patents, which confused the issue of who was the original inventor (partly because although Dr. Moustakas invented his first, Dr. Nakamura filed first).[citation needed] This new development revolutionized LED lighting, making high-power blue light sources practical, leading to the development of technologies like BlueRay, as well as allowing the bright high resolution screens of modern tablets and phones.[citation needed]
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who first patented a method to produce high-brightness blue LEDs?
Ah, so..
Shuji Nakamura
