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: The Toi invasion  was the invasion of northern Kyūshū by Jurchen pirates in 1019. At the time, Toi  meant "barbarian" in the Korean language. The Toi pirates sailed with about 50 ships from direction of Goryeo, then assaulted Tsushima and Iki, starting 27 March 1019. After the Iki Island garrison comprising 147 soldiers was wiped out, the pirates has proceed to Hakata Bay. For a week, using Noko Island  in the Hakata Bay as a base, they sacked villages and kidnapped over 1,000 Japanese, mostly women and young girls, for use as slaves. The Dazaifu, the administrative center of Kyūshū, then raised an army and successfully drove the pirates away. During the second failed raid to Matsuura 13 April 1019, three enemies were captured by the Japanese army. They were identified as Koreans. They said that they had guarded the borderland but had been captured by the Toi. However, this was unlikely, and the Japanese officers suspected them because there had been Korean pirates attacking Japan coasts during the Silla period. A few months later, the Goryeo delegate Jeong Jaryang  reported that Goryeo forces attacked the pirates off Wŏnsan and rescued about 260 Japanese. The Korean government then repatriated them to Japan where they were thanked by the Dazaifu and given rewards. There remain detailed reports by two captive women, Kura no Iwame and Tajihi no Akomi. These Jurchen pirates lived in what is today Hamgyŏngdo, North Korea.

Answer: Did the second raid to Matsuura succeed?


Question: Passage: Italy had seized military control over Libya from the Ottoman Empire during the Italo-Turkish War in 1912, but the new colony swiftly revolted and transferred large areas of land to Libyan local rule. Conflict between Italy and the Senussis - a Muslim political-religious tariqa based in Libya - erupted into major violence during World War I when the Senussis in Libya collaborated with the Ottomans against Italian troops. The Libyan Senussis also escalated the conflict with attacks on British forces in Egypt. Warfare between the British and the Senussis continued until 1917. In 1917 an exhausted Italy signed the Treaty of Acroma that acknowledged the effective independence of Libya from Italian control. In 1918, Tripolitanian rebels founded the Tripolitanian Republic, though the rest of the country remained under nominal Italian rule. Local agitation against Italy continued, such that by 1920 the Italian government was forced to recognise Senussi leader Sayid Idris as Emir of Cyrenaica and grant him autonomy. In 1922 Tripolitanian leaders offered Idris the position of Emir of Tripolitania. However before Idris was able to accept the position, the new Italian government of Benito Mussolini initiated a campaign of reconquest. From 1923 to 1924, Italian military forces regained all territory north of the Ghadames-Mizda-Beni Ulid region, with four fifths of the estimated population of Tripolitania and Fezzan within the Italian area; and Italian forces had regained the northern lowlands of Cyrenaica in during these two years. However attempts by Italian forces to occupy the forest hills of Jebel Akhtar were met with popular guerrilla resistance. This resistance was led by Senussi sheikh Omar Mukhtar.

Answer: How many years after Italy seized military control over Libya from the Ottoman Empire did Italy sign the Treaty of Acroma?


Question: Passage: The coastal areas of the Andaman Sea are characterized by mangrove forests and seagrass meadows. Mangroves cover between more than 600 km2  of the Thai shores of Malay Peninsula whereas seagrass meadows occupy an area of 79 km2 .:25-26 Mangroves are largely responsible for the high productivity of the coastal waters - their roots trap soil and sediment and provide shelter from predators and nursery for fish and small aquatic organisms. Their body protects the shore from the wind and waves, and their detritus are a part of the aquatic food chain. A significant part of the Thai mangrove forests in the Andaman Sea was removed during the extensive brackish water shrimp. Mangroves were also significantly damaged by the 2004 tsunami. They were partly replanted after that, but their area is still gradually decreasing due to human activities.:6-7 Other important sources of nutrients in the Andaman Sea are seagrass and the mud bottoms of lagoons and coastal areas. They also create a habitat or temporal shelter for many burrowing and benthic organisms. Many aquatic species migrate from and to seagrass either daily or at certain stages of their life cycle. The human activities which damage seagrass beds include waste water discharge from coastal industry, shrimp farms and other forms of coastal development, as well as trawling and the use of push nets and dragnets. The 2004 tsunami affected 3.5% of seagrass areas along the Andaman Sea via siltation and sand sedimentation and 1.5% suffered total habitat loss.:7.

Answer:
How many more acres, in km2, of mangrove forests than seagrass meadows occupy the Thai shores of the Malay Peninsula?
