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

Passage: The road building programme was also expanded, with capital expenditure increased to 8% of GDP, "the highest level achieved by any post-war government". Central government expenditure on roads went up from £125 million in 1963/64 to £225 million in 1967/68, while a number of road safety regulations were introduced, covering seat belts, lorry driver's hours, car and lorry standards, and an experimental 70 mile per hour speed limit. In Scotland, spending on trunk roads went up from £6.8 million in 1963/64 to £15.5 million in 1966/67, while in Wales, spending on Welsh roads went up from £21.2 million in 1963/64 to £31.4 million in 1966/67.
By how many millions of pounds did the central government expenditure on roads go up between 1963 and 1968?

Passage: The second half of the war was initiated by Pegu. To take advantage of Ava's dynastic succession crisis, Razadarit invaded Upper Burma in full force with a large flotilla in 1401. Ava's defenses held, and Razadarit and Minkhaung I of Ava agreed to another truce in 1403. The second truce lasted less than 5 years as Ava quickly went on an expansion spree, swallowing up Shan states of Kale and Mohnyin in the north, and Arakan in the west, between 1404 and 1406. Pegu could not allow Ava to get too strong, and renewed the war. In 1408, Peguan forces dislodged Avan troops from Arakan. Pegu also found an ally in the Shan state of Theinni , which too wanted to check Ava's ambitions. Between 1408 and 1413, Ava was forced to fight on multiple fronts: Theinni in the north, and Pegu in the south and in the west . Nonetheless, by 1412, Avan forces, led by Crown Prince Minye Kyawswa, had begun to gain an upper hand. Minye Kyawswa defeated Theinni and its Chinese allies in 1412. He invaded the Hanthawaddy country in full force in 1414, and conquered the Irrawaddy delta in 1415, forcing Razadarit to flee Pegu for Martaban. But Minye Kyawswa was killed in battle in March 1415.

After Razadarit invaded Upper Burma in full force with a large flotilla in 1401, how many years until another truce was agreed upon?
