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.

Question: Passage: The first two Buick automobiles were made in 1899 and 1900 at the "Buick Auto-Vim and Power Company" by chief-engineer Walter Lorenzo Marr, but company owner David Dunbar Buick was reluctant to begin making automobiles, being satisfied with stationary and marine engine production, so Marr left Buick in 1901 to found Marr (automobile) under his own name. His replacement was Eugene Richard, who applied for a patent in 1902 for Marrs valve-in-head (Overhead valve engine) engine, which patent, number 771,095, was awarded to Richard in the name of Buick in 1904. In 1903, the third Buick automobile was made, this time by Richard, but in 1904 Buick, whose company was now called "Buick Motor Company," moved to Flint, Michigan, and Richard stayed behind. Marr was rehired in Flint as chief engineer, to begin making automobiles in production. That year, 37 Buick automobiles were made, production increasing to 750 in 1905, 1,400 in 1906, 4,641 in 1907, and 8,800 in 1908, taking the number one spot away from close competitors Oldsmobile, Ford Motor Company, and Maxwell automobile.

Answer: How many Buick automobiles were built between 1904 and 1905?

Question: Passage: Literacy rate in Nauru, defined as "people who are currently enrolled in school and/or have reached at least grade 5 of primary education", is 96.5%, as of 2011. There are 3,190 students and 104 teachers, as of 2013. The 2011 census stated 4 percent of the population aged 15 years or older have a primary education, 91 percent have a secondary education, and 5 percent have a tertiary education. Education is based on the British system, which requires attendance from 5 to 16 years old. Students spend three years at preschool, six years of primary education, and four years of secondary school. Tertiary school is not required. An estimated 10.7 percent of the GDP was spend on education in 1999. As of 2013, there are five preschools, four primary schools, three secondary schools, and one tertiary school. The lone college, University of South Pacific, opened in the 1970s via distance courses, and in 1987 a campus was built on the island. It offers accounting, management, primary education, and English studies as majors.

Answer:
How many colleges are there in Nauru, as of 2013?
