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 2011, the Thessaloniki (regional unit) had a Gross Domestic Product of Euro18.293 billion (ranked 2nd amongst the countrys regional units), comparable to Bahrain or Cyprus, and a per capita of €15,900 (ranked 16th). In Purchasing Power Parity, the same indicators are €19,851 billion (2nd) and €17,200 (15th) respectively. In terms of comparison with the European Union average, Thessalonikis GDP per capita indicator stands at 63% the EU average and 69% in Purchasing Power Parity – this is comparable to the German state of Brandenburg. Overall, Thessaloniki accounts for 8.9% of the total economy of Greece. Between 1995 and 2008 Thessalonikis GDP saw an average growth rate of 4.1% per annum (ranging from +14.5% in 1996 to −11.1% in 2005) while in 2011 the economy contracted by −7.8%.
Between 1995 and 1996, what was the GDP growth rate of Thessalonikis?

Passage: New Caledonia is a major source for nickel and contains roughly 10% of the worlds known nickel supply. The islands contain about 7,100,000 tonnes of nickel. With the annual production of about 107,000 tonnes in 2009, New Caledonia was the Nickel mining in New Caledonia after Russia (266,000), Indonesia (189,000), Canada (181,000) and Australia (167,000). In recent years, the economy has suffered because of depressed international demand for nickel, due to the ongoing financial crisis of 2007–2008. Only a negligible amount of the land is suitable for cultivation, and food accounts for about 20% of imports. In addition to nickel, the substantial financial support from France and tourism are keys to the health of the economy. In the 2000s, large additions were made to nickel mining capacity. The Goro, New Caledonia is expected to be one of the largest nickel producing plants on Earth. When full-scale production begins in 2013 this plant will produce an estimated 20% of the global nickel supply. However, the need to respond to environmental concerns over the countrys globally recognized ecological heritage, may increasingly need to be factored into capitalization of mining operations.
How many countries rank above New Caledonia in nickel supply?

Passage: As of the Fall 2017 quarter, Louisiana Tech had an all-time record high enrollment of 12,873 students pursuing degrees in five academic colleges. The student body has members from every Louisiana parish, 47 U.S. states, and 64 foreign countries. Louisiana residents account for 85.0% of the student population, while out-of-state students and international students account for 11.1% and 4.0% of the student body, respectively. The student body at Louisiana Tech is 69.4% white, 13.3% black, 3.8% international students, and 13.5% other or "unknown" ethnicity. The student body consists of 50.2% women and 49.8% men.

Are more students at Louisiana Tech white or black?
