Problem: Age of Enlightenment:

The desire to explore, record and systematize knowledge had a meaningful impact on music publications. Jean-Jacques Rousseau's Dictionnaire de musique (published 1767 in Geneva and 1768 in Paris) was a leading text in the late 18th century. This widely available dictionary gave short definitions of words like genius and taste, and was clearly influenced by the Enlightenment movement. Another text influenced by Enlightenment values was Charles Burney's A General History of Music: From the Earliest Ages to the Present Period (1776), which was a historical survey and an attempt to rationalize elements in music systematically over time. Recently, musicologists have shown renewed interest in the ideas and consequences of the Enlightenment. For example, Rose Rosengard Subotnik's Deconstructive Variations (subtitled Music and Reason in Western Society) compares Mozart's Die Zauberflöte (1791) using the Enlightenment and Romantic perspectives, and concludes that the work is "an ideal musical representation of the Enlightenment".

What Mozart piece did Rose Rosengard Subotnik conclude is "an ideal musical representation of the Enlightenment"?

A: Die Zauberflöte (1791)


Problem: Hoping to extend the Continental System, Napoleon invaded Iberia and declared his brother Joseph the King of Spain in 1808. The Spanish and the Portuguese revolted with British support. The Peninsular War lasted six years, noted for its brutal guerrilla warfare, and culminated in an Allied victory. Fighting also erupted in Central Europe, as the Austrians launched another attack against the French in 1809. Napoleon defeated them at the Battle of Wagram, dissolving the Fifth Coalition formed against France. By 1811, Napoleon ruled over 70 million people across an empire that had domination in Europe, which had not witnessed this level of political consolidation since the days of the Roman Empire. He maintained his strategic status through a series of alliances and family appointments. He created a new aristocracy in France while allowing the return of nobles who had been forced into exile by the Revolution.
By 1811, what was the population of Napoleon's Empire?

Answer: over 70 million people


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Victoria later described her childhood as "rather melancholy". Her mother was extremely protective, and Victoria was raised largely isolated from other children under the so-called "Kensington System", an elaborate set of rules and protocols devised by the Duchess and her ambitious and domineering comptroller, Sir John Conroy, who was rumoured to be the Duchess's lover. The system prevented the princess from meeting people whom her mother and Conroy deemed undesirable (including most of her father's family), and was designed to render her weak and dependent upon them. The Duchess avoided the court because she was scandalised by the presence of King William's bastard children, and perhaps prompted the emergence of Victorian morality by insisting that her daughter avoid any appearance of sexual impropriety. Victoria shared a bedroom with her mother every night, studied with private tutors to a regular timetable, and spent her play-hours with her dolls and her King Charles spaniel, Dash. Her lessons included French, German, Italian, and Latin, but she spoke only English at home.
Who was the Dutchess' rumored friend?
A: unanswerable


Context and question: Czech distinguishes three genders—masculine, feminine, and neuter—and the masculine gender is subdivided into animate and inanimate. With few exceptions, feminine nouns in the nominative case end in -a, -e, or -ost; neuter nouns in -o, -e, or -í, and masculine nouns in a consonant. Adjectives agree in gender and animacy (for masculine nouns in the accusative or genitive singular and the nominative plural) with the nouns they modify. The main effect of gender in Czech is the difference in noun and adjective declension, but other effects include past-tense verb endings: for example, dělal (he did, or made); dělala (she did, or made) and dělalo (it did, or made).
What do Czech adjectives agree with in the nouns they modify?
Answer: gender and animacy


Question: Isambard Kingdom Brunel, the British engineer and railway builder, introduced the idea of a circular bar into the Swindon station pub in order that customers were served quickly and did not delay his trains. These island bars became popular as they also allowed staff to serve customers in several different rooms surrounding the bar.
Is there an answer to this question: Who pioneered the circular bar?

Answer: Isambard Kingdom Brunel


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.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The rabies vaccine was created in what year?
Ah, so..
1885
