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.

Example Input: Passage: With almost 80% of the total land area suitable for crop production and about 17% of the labor force engaged in farming, agriculture remains the primary occupation, accounting for 11% of GDP in 2001. Value of agricultural output grew at an average annual rate of 7.1% during 1968–73, but since 1975 the sector has been hampered by droughts (1975, 1977, and 1979), hurricanes (in 1979 and 1980), and slumping world prices and quota allocations for sugar (since 1985). In 1999, agricultural production was 0.4% higher than during 1989–91. The fertile Cibao Valley is the main agricultural center. In 1998, arable land totaled ; with land under permanent crops at .
Example Output: Agricultural production was 0.4% higher than how many years?

Example Input: Passage: Estimates for the total number of casualties in the war vary, because many deaths went unrecorded. Most suggest that some 60 million people died in the war, including about 20 million military personnel and 40 million civilians.Many of the civilians died because of deliberate genocide, massacres, mass-bombings, disease, and starvation. The Soviet Union lost around 27 million people during the war, including 8.7 million military and 19 million civilian deaths. A quarter of the people in the Soviet Union were wounded or killed. Germany sustained 5.3 million military losses, mostly on the Eastern Front and during the final battles in Germany. Of the total number of deaths in World War II, approximately 85 per cent—mostly Soviet and Chinese—were on the Allied side. Many of these deaths were caused by war crimes committed by German and Japanese forces in occupied territories. An estimated 11 to 17 million civilians died as a direct or as an indirect result of Nazi racist policies, including the Holocaust of around 6 million Jews, half of whom were Polish citizens, along with at least 1.9 million ethnic Poles. Millions of other Slavs , Roma, homosexuals, and other ethnic and minority groups were also killed. Between 1941 and 1945, over 200,000 ethnic Serbs, along with gypsies and Jews, were persecuted and murdered by the Axis-aligned Croatian Ustaše in Yugoslavia. Also, over 100,000 Poles were massacred by the Ukrainian Insurgent Army in the Volhynia massacres, between 1943 and 1945.
Example Output: Approximately how many Soviet civilians die in the war?

Example Input: Passage: TAccording to the U.S. Census Bureau, , Rhode Island had an estimated population of 1,056,298, which is an increase of 1,125, or 0.10%, from the prior year and an increase of 3,731, or 0.35%, since the year 2010. This includes a natural increase since the last census of 15,220 people (that is 66,973 births minus 51,753 deaths) and an increase due to net migration of 14,001 people into the state. Immigration to the United States from outside the United States resulted in a net increase of 18,965 people, and migration within the country produced a net decrease of 4,964 people.
Example Output:
How many more births and deaths combined were there than the natural increase of 15220 people?
