Input: Article: Burke's last publications were the Letters on a Regicide Peace (October 1796), called forth by negotiations for peace with France by the Pitt government. Burke regarded this as appeasement, injurious to national dignity and honour. In his Second Letter, Burke wrote of the French Revolutionary Government: "Individuality is left out of their scheme of government. The State is all in all. Everything is referred to the production of force; afterwards, everything is trusted to the use of it. It is military in its principle, in its maxims, in its spirit, and in all its movements. The State has dominion and conquest for its sole objects—dominion over minds by proselytism, over bodies by arms".

Now answer this question: What was Burke's final publication?

Output: Letters on a Regicide Peace

Input: Article: The instruments currently used in most classical music were largely invented before the mid-19th century (often much earlier) and codified in the 18th and 19th centuries. They consist of the instruments found in an orchestra or in a concert band, together with several other solo instruments (such as the piano, harpsichord, and organ). The symphony orchestra is the most widely known medium for classical music and includes members of the string, woodwind, brass, and percussion families of instruments. The concert band consists of members of the woodwind, brass, and percussion families. It generally has a larger variety and amount of woodwind and brass instruments than the orchestra but does not have a string section. However, many concert bands use a double bass. The vocal practices changed a great deal over the classical period, from the single line monophonic Gregorian chant done by monks in the Medieval period to the complex, polyphonic choral works of the Renaissance and subsequent periods, which used multiple independent vocal melodies at the same time.

Now answer this question: A symphony orchestra includes members of the string, woodwind, percussion and what other family of instruments?

Output: brass

Input: Article: The U.S. Census Bureau reports a 2010 population of 129,779, with 47,094 households and 25,854 families within the city of New Haven. The population density is 6,859.8 people per square mile (2,648.6/km²). There are 52,941 housing units at an average density of 2,808.5 per square mile (1,084.4/km²). The racial makeup of the city is 42.6% White, 35.4% African American, 0.5% Native American, 4.6% Asian, 0.1% Pacific Islander, 12.9% from other races, and 3.9% from two or more races. Hispanic or Latino residents of any race were 27.4% of the population. Non-Hispanic Whites were 31.8% of the population in 2010, down from 69.6% in 1970. The city's demography is shifting rapidly: New Haven has always been a city of immigrants and currently the Latino population is growing rapidly. Previous influxes among ethnic groups have been African-Americans in the postwar era, and Irish, Italian and (to a lesser degree) Slavic peoples in the prewar period.

Now answer this question: New Haven has a large immigrant population, what seems to be one of the main cause of it throughout the last century?

Output:
postwar
