Input: Read this: Herds of red and fallow deer also roam freely within much of Richmond and Bushy Park. A cull takes place each November and February to ensure numbers can be sustained. Epping Forest is also known for its fallow deer, which can frequently be seen in herds to the north of the Forest. A rare population of melanistic, black fallow deer is also maintained at the Deer Sanctuary near Theydon Bois. Muntjac deer, which escaped from deer parks at the turn of the twentieth century, are also found in the forest. While Londoners are accustomed to wildlife such as birds and foxes sharing the city, more recently urban deer have started becoming a regular feature, and whole herds of fallow and white-tailed deer come into residential areas at night to take advantage of the London's green spaces.
Question: When do culls to ensure sustainability of London's deer population occur?

Output: each November and February

Input: Read this: In 1901, 10-inch disc records were introduced, followed in 1903 by 12-inch records. These could play for more than three and four minutes respectively, while contemporary cylinders could only play for about two minutes. In an attempt to head off the disc advantage, Edison introduced the Amberol cylinder in 1909, with a maximum playing time of 4 minutes (at 160 rpm), which in turn were superseded by Blue Amberol Records, which had a playing surface made of celluloid, a plastic, which was far less fragile. Despite these improvements, during the 1910s discs decisively won this early format war, although Edison continued to produce new Blue Amberol cylinders for an ever-dwindling customer base until late in 1929. By 1919 the basic patents for the manufacture of lateral-cut disc records had expired, opening the field for countless companies to produce them. Analog disc records would dominate the home entertainment market until they were outsold by the digital compact disc in the late 1980s (which was in turn supplanted by digital audio recordings distributed via online music stores and Internet file sharing).
Question: What disc format was the least fragile prior to 1919?

Output: Amberol cylinder

Input: Read this: By the Middle Ages, large numbers of Jews lived in the Holy Roman Empire and had assimilated into German culture, including many Jews who had previously assimilated into French culture and had spoken a mixed Judeo-French language. Upon assimilating into German culture, the Jewish German peoples incorporated major parts of the German language and elements of other European languages into a mixed language known as Yiddish. However tolerance and assimilation of Jews in German society suddenly ended during the Crusades with many Jews being forcefully expelled from Germany and Western Yiddish disappeared as a language in Germany over the centuries, with German Jewish people fully adopting the German language.
Question: What group assimilated into German culture following the Middle Ages?

Output: unanswerable

Input: Read this: During the 1990s after NAFTA was signed, industrial development grew rapidly with foreign investment. Large factories known as maquiladoras were built to export manufactured goods to the United States and Canada. Today, most of the maquiladoras produce electronics, automobile, and aerospace components. There are more than 406 companies operating under the federal IMMEX or Prosec program in Chihuahua. The large portion of the manufacturing sector of the state is 425 factories divided into 25 industrial parks accounting for 12.47% of the maquiladoras in Mexico, which employ 294,026 people in the state. While export-driven manufacturing is one of the most important components of the state's economy, the industrial sector is quite diverse and can be broken down into several sectors, which are: electronics, agro-industrial, wood base manufacturing, mineral, and biotech. Similar to the rest of the country, small businesses continue to be the foundation of the state's economy. Small business employs the largest portion of the population.[citation needed]
Question: Most maquiladoras today produce what?

Output:
electronics, automobile, and aerospace components
