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.

Passage: Baillie was born at Glasgow, the son of Baillie of Jerviston. Having graduated there in 1620, he gave himself to the study of divinity. In 1631, after Baillie was ordained into the Church of Scotland, acting for some years as regent in the university, he was appointed to the living of Kilwinning in Ayrshire. His abilities soon made him a leading man. In 1638 he was a member of the Glasgow Assembly, when Presbyterianism was re-established in Scotland, and soon after he accompanied Leslie and the Scottish army as chaplain or preacher. In 1642, Baillie was made Professor of Divinity, Glasgow, and in the following year was selected as one of the five Scottish clergymen who were sent to the Westminster Assembly. In 1649, he was one of the commissioners sent to Holland for the purpose of inviting Charles II to Scotland, and of settling the terms of his admission to the government. He continued to take an active part in all the minor disputes of the church. In 1651, he was made professor of divinity in Glasgow University, and in 1661 was made principal. He died in August of the following year, his death likely hastened by his mortification at the apparently firm establishment of episcopacy in Scotland.
How many years after becoming professor of divinity in Glasgow University was he promoted to principal?
