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: Worldwide sales of hybrid vehicles produced by Toyota reached 1 million vehicles by May 31, 2007, and the 2 million mark was reached by August 2009, with hybrids sold in 50 countries. The 5 million hybrid sales milestone was reached in March 2013. During 2012, Toyota and Lexus hybrid models sold more than 1 million units a year for the first time, with 1.219 million units sold. During 2013, TMC sold 1.279 million units, and the 6 million sales milestone was achieved in December 2013, just nine months after its latest million unit milestone. The 7 million sales mark was reached in September 2014, again, selling one million hybrids in nine months, and the 8 million sales milestone was achieved in July 2015, just 10 months after the previous million-unit milestone. The 9 million sales mark was reached in April 2016, again, selling one million hybrids in just nine months, and the 10 million milestone in January 2017, one more time nine months later. Toyota estimates that up to January 31, 2017, its hybrids have saved about 7.66 billion U.S. gallons of gasoline (29 billion liters) compared to the amount used by gasoline-powered vehicles of similar size, and have emitted approximately 77 million fewer tons of CO2 emissions than would have been emitted by gasoline-powered vehicles of similar size and driving performance.
Did it take longer to go from 6 - 7 million units sold, or from 7 - 8 million units sold?

Passage: With the road win, the Rams improved their record to 6-6-1. The win was attributed to a late fourth quarter comeback drive by Rams quarterback Sam Bradford. The drive resulted in a touchdown reception by Brandon Gibson, bringing the score to 13-12. The Rams then scored a 2-point conversion on a quick pass to Danny Amendola, making the score 15-12 Rams. With under 2 minutes left in the game, the Bills attempted a comeback of their own, but came up short in what resulted in the Rams win.
How many loses did the Rams have after this game?

Passage: Following Jenkins' testimony and petitions from other West Indies merchants, the opposition in Parliament voted on 28 March 1738 to send "an Address" to the King, asking his Majesty to seek redress from Spain. More than one year later, all diplomatic means having been exhausted, on 10 July 1739 King George II authorised the Admiralty Board to seek maritime reprisals against Spain. On 20 July, Vice Admiral Edward Vernon and a fleet of warships departed Britain, bound for the West Indies, to attack Spanish ships and "possessions". War was not declared against Spain until Saturday, 23 October 1739 , one day after the attack on La Guaira, the principal port of the Province of Venezuela, which was controlled by the Royal Guipuzcoan Company of Caracas. After arriving at the island of Antigua in early October 1739, Vice Admiral Edward Vernon sent three ships under the command of Captain Thomas Waterhouse to intercept Spanish merchant ships that made the route between La Guaira and Porto Bello. Waterhouse spotted several small vessels in the port of La Guaira and decided to attack, implementing a rudimentary plan. The governor of the Province of Venezuela, Brigadier Don Gabriel de Zuloaga had prepared the port defences, and Spanish troops were well-commanded by Captain Don Francisco Saucedo. On 22 October, Waterhouse entered the port of La Guaira flying the Spanish flag. Expecting attack, the port gunners were not deceived by his ruse; they waited until the British squadron was within range and then simultaneously opened fire. After three hours of heavy shelling, Waterhouse ordered a withdrawal. The battered British squadron sailed to Jamaica to undertake emergency repairs. Trying later to explain his actions, Waterhouse argued that the capture of a few small Spanish vessels would not have justified the loss of his men.

How many days after King George II authorised the Admiralty Board to seek maritime reprisals against Spain did Vice Admiral Edward Vernon and a fleet of warships departed Britain?
