Q: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Passage: In the 19th century the Russian Empire, then including Latvia, was home to about five million Jews, the largest Jewish community in the world at the time. Subjected to religious persecution and violent pogroms, many emigrated, and between 1875 and 1914 around 120,000 arrived in the United Kingdom, mostly in England. The influx reached its peak in the late 1890s when large numbers of Jewish immigrants—mostly poor and semi-skilled or unskilled—settled in the East End of London; the concentration of Jews in some areas of London was almost 100 per cent of the population. Because of the influx of Jews and Russians into one part of Tottenham in North London, the area gained the nickname Little Russia.Some of the expatriates were revolutionaries, and many were unable to adapt to life in London. The social historian William J. Fishman writes that "the meschuggena (crazy) Anarchists were almost accepted as part of the East End landscape"; the terms "socialist" and "anarchist" had been conflated by the British press to refer generally to those with revolutionary beliefs.Several revolutionary factions were active in East and North London. One tactic often employed by revolutionaries in Russia was the expropriation of private property to fund radical activities. The influx of émigrés, and the associated rising rates of violent crime, led to widespread concerns and press coverage. As a result, the British government passed the Aliens Act 1905 in an attempt to reduce immigration. The popular press reflected the opinions of many; a leading article in the Manchester Evening Chronicle supported the bill to bar "the dirty, destitute, diseased, verminous and criminal foreigner who dumps himself on our soil". The journalist Robert Winder, in his examination of immigration into Britain, opines that the Act "gave official sanction to xenophobic reflexes which might ... have remained dormant".
