Article: 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 language did many of the Jews speak after the crusades?
Ans: German

Article: On July 11, 1877, a few days after the Bell Telephone Company was established, Bell married Mabel Hubbard (18571923) at the Hubbard estate in Cambridge, Massachusetts. His wedding present to his bride was to turn over 1,487 of his 1,497 shares in the newly formed Bell Telephone Company. Shortly thereafter, the newlyweds embarked on a year-long honeymoon in Europe. During that excursion, Bell took a handmade model of his telephone with him, making it a "working holiday". The courtship had begun years earlier; however, Bell waited until he was more financially secure before marrying. Although the telephone appeared to be an "instant" success, it was not initially a profitable venture and Bell's main sources of income were from lectures until after 1897. One unusual request exacted by his fiancee was that he use "Alec" rather than the family's earlier familiar name of "Aleck". From 1876, he would sign his name "Alec Bell". They had four children:

Question: How many children did Bell and Mabel have?
Ans: 4

Article: Throughout the second half of the 19th century, child labour began to decline in industrialised societies due to regulation and economic factors. The regulation of child labour began from the earliest days of the Industrial revolution. The first act to regulate child labour in Britain was passed in 1803. As early as 1802 and 1819 Factory Acts were passed to regulate the working hours of workhouse children in factories and cotton mills to 12 hours per day. These acts were largely ineffective and after radical agitation, by for example the "Short Time Committees" in 1831, a Royal Commission recommended in 1833 that children aged 1118 should work a maximum of 12 hours per day, children aged 911 a maximum of eight hours, and children under the age of nine were no longer permitted to work. This act however only applied to the textile industry, and further agitation led to another act in 1847 limiting both adults and children to 10-hour working days. Lord Shaftesbury was an outspoken advocate of regulating child labour.

Question: In 1833 at what age was the limit to working in a textile industry factory?
Ans: children under the age of nine

Article: Speculation that the Ashkenazi arose from Khazar stock surfaced in the later 19th century and has met with mixed fortunes in the scholarly literature. In late 2012 Eran Elhaik, a research associate studying genetics at the Johns Hopkins University School of Public Health, argued for Khazar descent in his paper The Missing Link of Jewish European Ancestry: Contrasting the Rhineland and the Khazarian Hypotheses. A 2013 study of Ashkenazi mitochondrial DNA found no significant evidence of Khazar contribution to the Ashkenazi Jewish DNA, as would be predicted by the Khazar hypothesis.

Question: Did Eran Elhaik, from Johns Hopkins University School of Public Health argue for or against Khazar descent?
Ans:
argued for Khazar descent
