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.

Ex Input:
Passage: In 1929, the Columbia Broadcasting System began making regular radio news broadcasts—five-minute summaries taken from reports from the United Press, one of the three wire services that supplied newspapers with national and international news. In December 1930 CBS chief William S. Paley hired journalist Paul W. White away from United Press as CBS's news editor. Paley put the radio network's news operation at the same level as entertainment, and authorized White to interrupt programming if events warranted. Along with other networks, CBS chafed at the breaking news embargo imposed upon radio by the wire services, which prevented them from using bulletins until they first appeared in print. CBS disregarded an embargo when it broke the story of the Lindbergh kidnapping in 1932, using live on-the-air reporting. Radio networks scooped print outlets with news of the 1932 presidential election.:485-486 In March 1933, White was named vice president and general manager in charge of news at CBS. As the first head of CBS News, he began to build an organization that soon established a legendary reputation.:486 In 1935, White hired Edward R. Murrow, and sent him to London in 1937 to run CBS Radio's European operation.:486 White led a staff that would come to include Charles Collingwood, William L. Shirer, Eric Sevareid, Bill Downs, John Charles Daly, Joseph C. Harsch:501 Cecil Brown, Elmer Davis, Quincy Howe, H. V. Kaltenborn, Robert Trout, and Lewis Shollenberger. "CBS was getting its ducks in a row for the biggest news story in history, World War II", wrote radio historian John Dunning.:487.

Ex Output:
After CBS started making regular radio news broadcasts, how many years passed before their first live on the air reporting?

Passage: In 2007, Kuwait supplied China with  of oil per day, accounting for 2.6% of Chinas total crude oil imports.  Saudi Arabia was Chinas top supplier with its shipments jumping 69.8 percent to 3.84 million tons (939,000 bbl/d), followed by Angola with 2.06 million tons (503,000 bbl/d), down 27.1 percent. Iran became third, with imports from the country shrinking 35.3 percent to 1.18 million tons (289,000 bbl/d). China is the worlds second-biggest oil consumer after the US. Abdullatif Al-Houti, Managing Director of International Marketing at state-run Kuwait Petroleum Corporation (KPC), told KUNA in October that Kuwait is on course for its China-bound crude oil export target of  by 2015, but success will heavily depend on the Sino-Kuwaiti refinery project. The two countries have been in talks for the planned  refinery in Chinas southern Guangdong Province. The complex is expected to be on-stream by 2020.

Ex Output:
How many less tons of crude oil than Angola does Iran supply China?

Passage: After Kraków had been devastated during the 1241 Mongol invasion of Poland, it was re-established according to Magdeburg Law by Prince Bolesław V the Chaste. In 1291 the Duchy of Kraków fell to the Přemyslid king Wenceslaus II of Bohemia who in 1300 also became King of Poland. Upon the extinction of the Přemyslids in 1306, the Piast duke Władysław I the Elbow-high assumed the rule at Kraków, while in 1310 the Bohemian Kingdom passed to the House of Luxembourg. The new king, John of Bohemia, continued to claim the Polish royal title and moreover sought to vassalize the Piast dukes of the adjacent Silesian region.

Ex Output:

How many years after Duchy of Kraków fell to the Přemyslid king Wenceslaus II of Bohemia did Wenceslaus II become King of Poland?
