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: In 1642, Güshi Khan, founder of the Khoshut Khanate, overthrew the prince of Tsang and made the 5th Dalai Lama the highest spiritual and political authority in Tibet, establishing the regime known as Ganden Phodrang. Tsewang Rabtan invaded Tibet in 1717, deposed the pretender to the position of Dalai Lama of Lha-bzang Khan, the last ruler of the Khoshut Khanate, and killed Lha-bzang Khan and his entire family. They also viciously destroyed a small force in the Battle of the Salween River which the Kangxi Emperor of the Qing dynasty had sent to clear traditional trade routes in 1718. In response, an expedition sent by Kangxi Emperor, together with Tibetan forces under Polhané Sönam Topgyé of Tsang and Kangchennas , the governor of Western Tibet, expelled the Dzungars from Tibet in 1720. This began the Qing rule of Tibet, which lasted until the fall of the Qing dynasty in 1912.
How many years after Tsewang Rabtan invaded Tibet did the Battle of the Salween River take place?

Passage: Pope Julius II planned far more for St Peters than Nicholas Vs program of repair or modification. Julius was at that time planning his own tomb, which was to be designed and adorned with sculpture by Michelangelo and placed within St Peters.  In 1505 Julius made a decision to demolish the ancient basilica and replace it with a monumental structure to house his enormous tomb and "aggrandize himself in the popular imagination".  A competition was held, and a number of the designs have survived at the Uffizi Gallery. A succession of popes and architects followed in the next 120 years, their combined efforts resulting in the present building. The scheme begun by Julius II continued through the reigns of Pope Leo X (1513–1521), Pope Hadrian VI (1522–1523). Pope Clement VII (1523–1534), Pope Paul III (1534–1549), Pope Julius III (1550–1555), Pope Marcellus II (1555), Pope Paul IV (1555–1559), Pope Pius IV (1559–1565), Pope Pius V (saint) (1565–1572), Pope Gregory XIII (1572–1585), Pope Sixtus V (1585–1590), Pope Urban VII (1590), Pope Gregory XIV (1590–1591), Pope Innocent IX (1591), Pope Clement VIII (1592–1605), Pope Leo XI (1605), Pope Paul V (1605–1621), Pope Gregory XV (1621–1623), Pope Urban VIII (1623–1644) and Pope Innocent X (1644–1655).
How many more years did Pope Gregory XV reign than Pope Leo XI?

Passage: The first comprehensive theories of management appeared around 1920. The Harvard Business School offered the first Master of Business Administration degree (MBA) in 1921. People like Henri Fayol (1841-1925) and Alexander Hamilton Church (1866-1936) described the various branches of management and their inter-relationships. In the early-20th century, people like Ordway Tead (1891-1973), Walter Dill Scott (1869-1955) and J. Mooney applied the principles of psychology to management. Other writers, such as Elton Mayo (1880-1949), Mary Follett (1868-1933), Chester Barnard (1886-1961), Max Weber (1864-1920), who saw what he called the "administrator" as bureaucrat, Rensis Likert (1903-1981), and Chris Argyris (born 1923) approached the phenomenon of management from a sociology perspective.
