TASK DEFINITION: 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.
PROBLEM: Passage: During the Democratic Kampuchea days, the 68,000-member Khmer Rouge-dominated CPNLAF  force, which completed its conquest of Phnom Penh, Cambodia in April 1975, was renamed the RAK . This name dated back to the peasant uprising that broke out in the Samlot district of Battambang Province in 1967. Under its long-time commander and then Minister of Defense Son Sen, the RAK had 230 battalions in 35 to 40 regiments and in 12 to 14 brigades. The command structure in units was based on three-person committees in which the political commissar ranked higher than the military commander and his deputy. Cambodia was divided into zones and special sectors by the RAK, the boundaries of which changed slightly over the years. Within these areas, the RAK's first task was the peremptory execution of former Khmer National Armed Forces  officers and of their families, without trial or fanfare to eliminate KR enemies. The RAK's next priority was to consolidate into a national army the separate forces that were operating more or less autonomously in the various zones. The Khmer Rouge units were commanded by zonal secretaries who were simultaneously party and military officers, some of whom were said to have manifested "warlord characteristics". Troops from one zone frequently were sent to another zone to enforce discipline. These efforts to discipline zonal secretaries and their dissident or ideologically impure cadres gave rise to the purges that were to decimate RAK ranks, to undermine the morale of the victorious army, and to generate the seeds of rebellion. In this way, the KR used the RAK to sustain and fuel its violent campaign.

SOLUTION: From what year did the name RAK originate?

PROBLEM: Passage: The 8,878 housing units averaged 685.5 per square mile (264.7/km²), of which 6,287 (73.6%) were owner-occupied, and 2,256 (26.4%) were occupied by renters. The homeowner vacancy rate was 1.2%; the rental vacancy rate was 5.2%.  Around 17,769 people (77.1% of the population) lived in owner-occupied housing units and 5,280 people (22.9%) lived in rental housing units.

SOLUTION: How many more housing units were owner-occupied than occupied by renters?

PROBLEM: Passage: In 1991, the KFC name was officially adopted, although it was already widely known by that initialism. Kyle Craig, president of KFC US, admitted the change was an attempt to distance the chain from the unhealthy connotations of "fried". The early 1990s saw a number of successful major products launched throughout the chain, including spicy "Hot Wings" (launched in 1990), popcorn chicken (1992), and internationally, the "Zinger", a spicy chicken fillet burger (1993). By 1994, KFC had 5,149 outlets in the US, and 9,407 overall, with over 100,000 employees. In August 1997, PepsiCo spun off its restaurants division as a public company valued at US$4.5 billion (around US$6.5 billion in 2013). The new company was named Tricon Global Restaurants, and at the time had 30,000 outlets and annual sales of US$10 billion (around US$14 billion in 2013), making it second in the world only to McDonalds. Tricon was renamed Yum! Brands in May 2002.

SOLUTION:
As of 1997, which company had higher annual sales, Tricon Global Restaurants or McDonalds?
