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.

Input: Consider Input: Passage: Over the years the city has been home to people of various ethnicities, resulting in a range of different traditions and cultural practices. In one decade, the population increased from 427,045 in 1991 to 671,805 in 2001. The population was projected to reach 915,071 in 2011 and 1,319,597 by 2021. To keep up this population growth, the KMC-controlled area of  has expanded to  in 2001. With this new area, the population density which was 85 in 1991 is still 85 in 2001; it is likely to jump to 111 in 2011 and 161 in 2021.

Output: How many more people populated the city in 2001 than in 1991?


Input: Consider Input: Passage: Looking to muster their first winning streak of the season, the Washington Redskins took on the rival New York Giants on Monday Night Football. To add to the fanfare, Redskins owner Daniel Snyder hired Bruce Allen to be the new General Manager. However, the Redskins came out flat, and trailed 24-0 by halftime. With a chance to kick a field goal as the half ended to cut it to a 24-3 deficit, the Redskins tried one of the most ill-advised and ill-fated fake field goal attempts of all-time. Redskins P Hunter Smith sent the entire offensive line in motion, along with K Graham Gano. The first attempt was foiled by a Giants time-out. The second attempt was intercepted and almost taken back for a 31-0 lead. In the 2nd half, the Redskins finally got on the board, scoring on a touchdown pass to Fred Davis. However, it was too little, too late, as K Graham Gano missed the extra point. The Redskins would not score again until it was 38-6 Giants. RB Quinton Ganther scored on a 2-yard scamper, but the Redskins came up a foot short on the 2-point conversion, which sealed any slim chance there was of a comeback. When all was said and done, the Giants won 45-12. With the crushing loss, Washington fell to 4-10, losing 10 games or more for the third time in six seasons.

Output: How many points did the Giants win by?


Input: Consider Input: Passage: When Sigurd died in 1130, Harald broke his oath. Sigurd's son Magnus was proclaimed king, but Harald also claimed the royal title, and received much support. A settlement was reached whereby Magnus and Harald would both be kings and co-rulers. Peace between them lasted until 1134, when open war broke out. In 1135 Harald succeeded in defeating and capturing Magnus in Bergen. Magnus was blinded, castrated, mutilated and imprisoned in a monastery. He was thereafter known as Magnus the Blind. At about the same time Sigurd Slembe, another man from Iceland, arrived claiming to be a son of Magnus Barefoot. He claimed to have gone through an ordeal by fire in Denmark to prove his claim. Harald did not recognize him as his half-brother. In 1136 Sigurd murdered Harald in his sleep in Bergen, and had himself proclaimed king. Harald's supporters would not accept him and had Harald's two infant sons, Sigurd Munn and Inge Crouchback, named king. Sigurd Slembe liberated Magnus the Blind from his enforced monastic life and allied himself with him. The war between Sigurd Slembe and Magnus the Blind on the one side, and Harald Gille's old supporters with his young sons on the other, dragged on until 1139, when Magnus and Sigurd were defeated in Battle of Holmengrå fought near Hvaler. Magnus was killed in the battle, Sigurd was captured and tortured to death.


Output: How did Harald die?
