Detailed Instructions: 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.
Q: Passage: Bristol was founded by 1000; by about 1020, it was a trading centre with a mint producing silver pennies bearing its name. By 1067 Brycgstow was a well-fortified burh, and that year the townsmen beat off a raiding party from Ireland led by three of Harold Godwinson's sons. Under Norman rule, the town had one of the strongest castles in southern England. Bristol was the place of exile for Diarmait Mac Murchada, the Irish king of Leinster, after being overthrown. The Bristol merchants subsequently played a prominent role in funding Richard Strongbow de Clare and the Norman invasion of Ireland.
The port developed in the 11th century around the confluence of the Rivers Frome and Avon, adjacent to Bristol Bridge just outside the town walls. By the 12th century Bristol was an important port, handling much of England's trade with Ireland, including slaves. There was also an important Jewish community in Bristol from the late 12th century through to the late 13th century when all Jews were expelled from England. The stone bridge built in 1247 was replaced by the current bridge during the 1760s. The town incorporated neighbouring suburbs and became a county in 1373, the first town in England to be given this status. During this period, Bristol became a shipbuilding and manufacturing centre. By the 14th century Bristol, York and Norwich were England's largest medieval towns after London. One-third to one-half of the population died in the Black Death of 1348–49, which checked population growth, and its population remained between 10,000 and 12,000 for most of the 15th and 16th centuries.
