This task involves annotating the answer type to a given question that involve some kind of complex reasoning (including numerical reasoning). Note that the questions require looking at more than one part of the passage to answer. There are 3 possible answer types (i) spans, (ii) numbers and (iii) dates. If the answer can be found in the passage, label it as "span". If the answer is a number, label as "number". Similarly, label "date" if you think the answer to the given question is a date.

Example Input: Passage: The violence and terror of Pontiac's War convinced many western Pennsylvanians that their government was not doing enough to protect them. This discontent was manifested most seriously in an uprising led by a vigilante group that came to be known as the Paxton Boys, so-called because they were primarily from the area around the Pennsylvania village of Paxton . The Paxtonians turned their anger towards Native Americans—many of them Christians—who lived peacefully in small enclaves in the midst of white Pennsylvania settlements. Prompted by rumors that a Native war party had been seen at the Native village of Conestoga, on December 14, 1763, a group of more than 50 Paxton Boys marched on the village and murdered the six Susquehannocks they found there. Pennsylvania officials placed the remaining 16 Susquehannocks in protective custody in Lancaster, but on December 27 the Paxton Boys broke into the jail and slaughtered most of them. Governor John Penn issued bounties for the arrest of the murderers, but no one came forward to identify them. The Paxton Boys then set their sights on other Native Americans living within eastern Pennsylvania, many of whom fled to Philadelphia for protection. Several hundred Paxtonians marched on Philadelphia in January 1764, where the presence of British troops and Philadelphia militia prevented them from committing more violence. Benjamin Franklin, who had helped organize the local militia, negotiated with the Paxton leaders and brought an end to the immediate crisis. Franklin published a scathing indictment of the Paxton Boys. "If an Indian injures me," he asked, "does it follow that I may revenge that Injury on all Indians?" One leader of the Paxton Boys was Lazarus Stewart who would be killed in the Wyoming Massacre of 1778.
Question: When did the march of the Paxtonians take place?
Example Output: date

Example Input: 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.
Question: How many years after becoming professor of divinity in Glasgow University was he promoted to principal?
