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: In 1860s, the relations between Qatar and Bahrain deteriorated with a series of small disputes. Hostilities emerged when, in 1867, Bahrain arrested a Qatari Bedouin in the Qatari mainland and deported him to Bahrain. In response, the Qataris, led by the Naim tribe, defeated the Bahraini army that was based on the peninsula, effectively expelling them. These tensions led Bahrain, allied with Abu Dhabi, to attack Qatar. The conflict failed to pacify and resulted in an escalation between the two parties in the following year. In October 1867, the Bahraini Hakim Mohammed al Khalifa, sent his brother, Ali Al Khalifa, with a force of 500 men in 24 boats to attack Qatar. He was joined by a force of 200 men under Ahmed al Khalifa. Additionally, Bahrain's ally Abu Dhabi sent 2,000 troops in 70 boats. The attack on Qatar led to the sacking of Bida  and Wakra. A British record later stated "that the towns of Doha and Wakrah were, at the end of 1867 temporarily blotted out of existence, the houses being dismantled and the inhabitants deported". A Qatari counterattack followed the next year, resulting in the destruction of most of the Bahraini naval vessels deployed. The 1868 attack resulted in some 1,000 individuals killed and 60 ships destroyed.
answer:
How many men did Ali Al Khalifa have under his command?


question:
Passage: Raj Singh Dungarpur is credited for the selection of Tendulkar for the Indian tour of Pakistan national cricket team in late 1989, after one first class season. The Indian selection committee had shown interest in selecting Tendulkar for the Indian cricket team in West Indies in 1988–89 held earlier that year, but eventually did not select him, as they did not want him to be exposed to the dominant fast bowlers of the West Indies so early in his career. Tendulkar made his Test cricket debut against Pakistan in Indian cricket team in Pakistan in 1989–90 aged 16 years and 205 days. He made 15 runs, being bowled by Waqar Younis, who also made his debut in that match, but was noted for how he handled numerous blows to his body at the hands of the Pakistani pace attack. In the fourth and final Test in Sialkot, he was hit on the nose by a bouncer bowled by Younis, but he declined medical assistance and continued to bat even as he gushed blood from it. In a 20-over exhibition game in Peshawar, held in parallel with the bilateral series, Tendulkar made 53 runs off 18 balls, including an over in which he scored 27 runs (6, 4, 0, 6, 6, 6) off leg-spinner Abdul Qadir (cricketer). This was later called "one of the best innings I have seen" by the then Indian captain Krishnamachari Srikkanth. In all, he scored 215 runs at an average of 35.83 in the Test series, and was dismissed without scoring a run in the only One Day International (ODI) he played. Thus Sachin Tendulkar became the youngest player to debut for India in Test cricket at the age of 16 years and 205 days and also the youngest player to debut for India in One Day International at the age of 16 years and 238 days.
answer:
How many days after the age of 16 was Tendulkar when he debuted for India in Test cricket?


question:
Passage: By 2012, the USMC reported fleetwide readiness rate had risen to 68 percent; however, the DODs Inspector General later found 167 of 200 reports had "improperly recorded" information. Captain Richard Ulsh blamed these errors on incompetence and said that they were "not malicious" or deliberate. The required mission capable rate was 82%, but the average was 53% from June 2007 to May 2010. In 2010, Naval Air Systems Command aimed for an 85% reliability rate by 2018. From 2009 to 2014, readiness rates rose 25 percent to the "high 80s", while operating cost had dropped 20 percent to $9,520 through a rigorous maintenance improvement program that focused on diagnosing problems before failures occur. , although the V-22 requires higher maintenance and has lower availability (62%) than traditional helicopters, it also has a lower incidence rate. The average cost per flight hour is , whereas the Sikorsky CH-53E Super Stallion cost about $20,000 per flight hour in 2007. V-22 Total cost of ownership was $83,000 per hour in 2013.
answer:

How many more dollars did the V-22 Total cost of ownership per hour in 2013 compared to Sikorsky CH-53E Super Stallion cost per flight hour in 2007?
