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: 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.

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

Question: Passage: Centered on Post Oak Boulevard and Westheimer Road, the Uptown Houston boomed during the 1970s and early 1980s when a collection of midrise office buildings, hotels, and retail developments appeared along Interstate 610 West. Uptown became one of the most prominent instances of an edge city. The tallest building in Uptown is the 64-floor, -tall, Philip Johnson and John Burgee designed landmark Williams Tower (known as the Transco Tower until 1999). At the time of construction, it was believed to be the worlds tallest skyscraper outside a central business district. The new 20-story Skanska building and BBVA Compass Plaza are the newest office buildings built in Uptown after 30 years. The Uptown District is also home to buildings designed by noted architects I. M. Pei, César Pelli, and Philip Johnson. In the late 1990s and early 2000s, a mini-boom of midrise and highrise Tower block construction occurred, with several over 30 stories tall. Since 2000 more than 30 high-rise buildings have gone up in Houston; all told, 72 high-rises tower over the city, which adds up to about 8,300 units. In 2002, Uptown had more than 23 million square feet (2,100,000 m²) of office space with 16 million square feet (1,500,000 m²) of class A office space.

Answer:
How many more millions of square feet of office space total is there than class A office space?
