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: Due to a conflict involving the Orioles' schedule, the Ravens opened the regular season on the road against the Broncos in what would be the first time a defending Super Bowl champion team has done so since the Buccaneers in 2003 when they opened their regular season against the Eagles.  This would be a rematch of last year's AFC Divisional game. The Ravens drew first blood when Joe Flacco found Vonta Leach on a 2-yard touchdown pass to take the lead 7-0 in the first quarter for the only score of the period.  The Broncos would tie the game in the 2nd quarter with Peyton Manning finding Julius Thomas on a 24-yard pass to take the game to 7-7.  The Ravens moved back into the lead when Ray Rice ran for a 1-yard touchdown to make the score 14-7.  Peyton would find Julius again on a 23-yard pass to make the score 14-14 for another tie before the Ravens kicker Justin Tucker nailed a 25-yard field goal to make the score 17-14 at halftime.  In the 3rd quarter, the Broncos went right back to work as Peyton found Andre Caldwell on a 28-yard touchdown pass to take a 21-17 lead followed up with finding Wes Welker on 2 consecutive passes from 5 yards and 2 yards out for an increase in the lead first to 28-17 and then to 35-17.  Later on in the quarter, Peyton would find Demaryius Thomas on a 26-yard pass to increase the lead to 42-17.  The Ravens tried to rally a comeback in the last quarter, with Flacco finding Marlon Brown on a 13-yard pass to shorten the Broncos' lead 42-24 followed up by Tucker's 30-yard field goal to make the score 42-27.  However, the Broncos wrapped things up in the game when Peyton found D. Thomas again on a 78-yard pass to make the final score 49-27.  The Ravens began their season 0-1 for the first time under John Harbaugh as head coach and Joe Flacco as their starter.  They also lost their first regular season opening game since 2007 as well as becoming the 2nd straight defending Super Bowl champion team to lose their season opener.
answer:
How many field goals did the Ravens have?


question:
Passage: The Jurchens were a Tungusic-speaking group of semi-agrarian tribes inhabiting areas of northeast Asia that are now part of Northeast China. Many of the Jurchen tribes were vassals of the Liao dynasty , an empire ruled by the nomadic Khitans that included most of modern Mongolia, a portion of North China, Northeast China, northern Korea, and parts of the Russian Far East. To the south of the Liao lay the Han Chinese Song Empire . The Song and Liao were at peace, but since a military defeat to the Liao in 1005, the Song paid its northern neighbor an annual indemnity of 200,000 bolts of silk and 100,000 ounces of silver. In 1114, the chieftain Wanyan Aguda  united the disparate Jurchen tribes and led a revolt against the Liao. In 1115 he named himself emperor of the Jin "golden" dynasty . Informed by a Liao defector of the success of the Jurchen uprising, the Song emperor Huizong  and his highest military commander the eunuch Tong Guan saw the Liao weakness as an opportunity to recover the Sixteen Prefectures, a line of fortified cities and passes that the Liao had annexed from the Shatuo Turk Later Jin in 938, and that the Song had repeatedly but unsuccessfully tried to reconquer. The Song thus sought an alliance with the Jin against their common enemy the Liao.
answer:
How many areas did the Khitans rule over?


question:
Passage: William A. Thorpe was killed in an accident in 1918, his business continuing to operate on the island to the present day. In 1920 the Norwegian ship Spangereid caught fire and sank at her mooring at James Bay, depositing quantities of coal on the beach below the wharf. A census in 1921 showed the islands population was 3,747. The first islanders left to work at Ascension Island in 1921, which was made a dependency of St Helena in 1922. Thomas R. Bruce (postmaster 1898–1928) was the first islander to design a postage stamp, the 1922–1937 George V ship-design—this significantly contributed to island revenues for several years. South African coinage became legal tender in 1923, reflecting the high level of trade with that country. There were nine deaths from whooping cough between 1920 and 1929 and 2,200 cases of measles in 1932. The first car, an Austin 7, was imported into the island in 1929. A census in 1931 showed a population of 3,995 (and a goat population of nearly 1,500). Cable & Wireless plc absorbed the Eastern Telegraph Company in 1934. Tristan da Cunha was made a dependency of St Helena in 1938.
answer:

How many years after Ascension Island was made a dependency of St Helena was Tristan da Cunha made a dependency?
