Given the task definition, example input & output, solve the new input case.
In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
Example: what is the first event mentioned?, Context: The Russian Revolution is the series of revolutions in Russia in 1917, which destroyed the Tsarist autocracy and led to the creation of the Soviet Union. Following the abdication of Nicholas II of Russia, the Russian Provisional Government was established. In October 1917, a red faction revolution occurred in which the Red Guard, armed groups of workers and deserting soldiers directed by the Bolshevik Party, seized control of Saint Petersburg (then known as Petrograd) and began an immediate armed takeover of cities and villages throughout the former Russian Empire.
Output: Russian Revolution
This is a good example, and the Russian Revolution is the first event mentioned.

New input case for you: When did Sylvester Primer publish both his works?, Context: The traditional Charleston accent has long been noted in the state and throughout the South. It is typically heard in wealthy white families who trace their families back generations in the city. It has ingliding or monophthongal long mid-vowels, raises ay and aw in certain environments, and is nonrhotic. Sylvester Primer of the College of Charleston wrote about aspects of the local dialect in his late 19th-century works: "Charleston Provincialisms" (1887)  and "The Huguenot Element in Charleston's Provincialisms", published in a German journal. He believed the accent was based on the English as it was spoken by the earliest settlers, therefore derived from Elizabethan England and preserved with modifications by Charleston speakers. The rapidly disappearing "Charleston accent" is still noted in the local pronunciation of the city's name. Some elderly (and usually upper-class) Charleston natives ignore the 'r' and elongate the first vowel, pronouncing the name as "Chah-l-ston". Some observers attribute these unique features of Charleston's speech to its early settlement by French Huguenots and Sephardic Jews (who were primarily English speakers from London), both of whom played influential roles in Charleston's early development and history.[citation needed]
Output:
late 19th-century
