instruction:
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: A total of United States dollar50.1 billion (equivalent to $}} presently) was involved, or 11% of the total war expenditures of the U.S. In all, $31.4 billion (equivalent to $}} today) went to Britain and its Empire, $11.3 billion (equivalent to $}} today) to the Soviet Union, $3.2 billion (equivalent to $}} today) to France, $1.6 billion (equivalent to $}} today) to China, and the remaining $2.6 billion to the other Allies. Reverse lend-lease policies comprised services such as rent on bases used by the U.S., and totaled $7.8 billion; of this, $6.8 billion came from the British and the Commonwealth of Nations, mostly Australia and India. The terms of the agreement provided that the materiel was to be used until returned or destroyed. In practice very little equipment was in usable shape for peacetime uses. Supplies that arrived after the termination date were sold to Britain at a large discount for £1.075 billion, using long-term loans from the United States. Canada was not part of Lend Lease. However it operated a similar program called Billion Dollar Gift and Mutual Aid that sent a loan of $1 billion and $3.4 billion in supplies and services to Britain and other Allies.
answer:
Did Canada send more in loans or supplies to Britain and other Allies?

Passage: Hoping to rebound from their road loss to the Seahawks, the Bears went home for a Week 12 interconference duel with the Denver Broncos. In the first quarter, Chicago got the early lead as kicker Robbie Gould made a 24-yard field goal. The Broncos tied the game as kicker Jason Elam made a 23-yard field goal. In the second quarter, Denver took the lead as RB Andre Hall got a 16-yard TD run. Afterwards, the Bears responded with Gould kicking a 44-yard field goal. The Broncos ended the half with Elam kicking a 22-yard field goal. In the third quarter, the Bears tied the game with WR/KR/PR Devin Hester returning a punt 75 yards for a touchdown. Denver responded with FB Cecil Sapp getting a 5-yard TD run, but afterwards, Hester went right back to work for Chicago as he returned the following kickoff 88 yards for a touchdown. Afterwards, the Broncos replied with QB Jay Cutler completing a 68-yard TD pass to WR Brandon Marshall. In the fourth quarter, Denver increased its lead with Cutler completing a 14-yard TD pass to TE Tony Scheffler. Afterwards, the Bears tied the game with RB Adrian Peterson getting a 4-yard TD run, along with QB Rex Grossman completing a 3-yard TD pass to WR Bernard Berrian. In overtime, Chicago came out on top as Gould made the game-winning 39-yard field goal. Devin Hester became the fifth player since 1970 to return a kickoff and a punt for a touchdown in the same game.
answer:
How many field goals did Jason Elam kick?

Passage: The clearance of the indigenous forest for the distillation of spirits, tanning and agricultural development began to lead to shortage of wood by the 1680s. The numbers of rats and goats had reached plague proportions by the 1690s, leading to the destruction of food crops and young tree shoots. Neither an increase on duty on the locally produced Arrack (drink) nor a duty on all firewood helped reduce the deforestation whilst attempts to reforest the island by governor John Roberts (1708–1711) were not followed up by his immediate successors. The Great Wood, which once extended from Deadwood Plain to Prosperous Bay Plain, was reported in 1710 as not having a single tree left standing. An early mention of the problems of soil erosion was made in 1718 when a waterspout broke over Sandy Bay, on the southern coast. Against the background of this erosion, several years of drought and the general dependency of St Helena, in 1715 governor Isaac Pyke (1714–1719) made the serious suggestion to the Company that appreciable savings could be made by moving the population to Mauritius, evacuated by the French in 1710. However, with the outbreak of war with other European countries, the Company continued to subsidise the island because of its strategic location. An ordinance was passed in 1731 to preserve the woodlands through the reduction in the goat population. Despite the clear connection between deforestation and the increasing number of floods (in 1732, 1734, 1736, 1747, 1756 and 1787) the East India Company’s Court of Directors gave little support to efforts by governors to eradicate the goat problem. Rats were observed in 1731 building nests in trees two feet across, a visitor in 1717 commenting that the vast number of wild cats preferred to live off young partridges than the rats. An outbreak of plague in 1743 was attributed to the release of infected rats from ships arriving from India. By 1757, soldiers were employed in killing the wild cats.
answer:

How many different years did they have floods?
