Detailed Instructions: This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning).
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.
Q: Passage: The poll tax was resurrected during the 17th century, usually related to a military emergency. It was imposed by Charles I of England in 1641 to finance the raising of the army against the Scottish and Irish uprisings. With the Restoration (England) of Charles II of England in 1660, the Convention Parliament (1660) instituted a poll tax to finance the disbanding of the New Model Army (pay arrears, etc.) (12 Charles II c.9). The poll tax was assessed according to "rank", e.g. dukes paid 100, earls 60, knights 20, esquires 10. Eldest sons paid 2/3rds of their fathers rank, widows paid a third of their late husbands rank. The members of the livery companies paid according to companys rank (e.g. masters of first-tier guilds like the Mercers paid 10, whereas masters of fifth-tier guilds, like the Clerks, paid 5 shillings). Professionals also paid differing rates, e.g. physicians (10), judges (20), advocates (5), attorneys (3), and so on. Anyone with property (land, etc.) paid 40 shillings per 100 earned, anyone over the age of 16 and unmarried paid 12-pence and everyone else over 16 paid 6-pence.
A:
How many more pence did those who were over 16 and unmarried pay for poll tax than anyone else over 16?
