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: The Turkish-Armenian war, known in Turkey as the Eastern Operation or Eastern Front  of the Turkish War of Independence, refers to a conflict in the autumn of 1920 between the First Republic of Armenia and the Turkish nationalists, following the signing of the Treaty of Sèvres. After an initial Armenian occupation of what is now eastern Turkey, the army of the Turkish National Movement under Kâzım Karabekir reversed the Armenian gains and further invaded and defeated Armenia, also recapturing territory which the Ottoman Empire had lost to the Russian Empire in 1855 and 1878. The Turkish military victory was followed by Soviet Russia's occupation and sovietization of Armenia. The Treaty of Moscow  between Soviet Russia and the Grand National Assembly of Turkey and the related Treaty of Kars  confirmed the territorial gains made by Karabekir and established the modern Turkish-Armenian border. Armenia had territorial disputes with the Ottoman Empire. The Ottomans had tried to move the Armenians during the Armenian Genocide and occupied the South Caucasus during Summer 1918. Armenia resisted until the Allied forces won WWI. The Ottomans maintained their troops along their territorial gains until Spring 1919.
For what time span was the Ottoman Empire able to maintain the territorial gains they won from Armenia?

Passage: After the week 12 win over the Cleveland Browns, the Bengals stayed home for a game against the Detroit Lions. The first and only score of the first quarter for both teams came when the Lions' Calvin Johnson caught a 54-yard pass from Matthew Stafford for a touchdown, which made the Lions lead 7-0 at the end of the first quarter. In the second quarter, with 11:50 left, Jonathan Fanene got a 45-yard interception pass for a touchdown, which tied the game 7-7. Later in the 2nd quarter, with 5:50 left, Chad Ochocinco caught a 36-yard pass from Carson Palmer for a touchdown, which made the Bengals lead by 7. In celebration, he donned a poncho and sombrero, for which the NFL handed him another $20,000 fine. A 44-yard field goal by Shayne Graham with 0:09 left in the half made the halftime score 17-7. A 39-yard field goal by Shayne Graham was the only score for both teams in the 3rd quarter. With 8:11 left in the 4th quarter, Shayne Graham kicked a 23-yard field goal, to make the score 23-7. The Lions later had a 2-yard touchdown run by Kevin Smith with 1:36 left in the game. The Lions then attempted a 2-point conversion, but failed, making the final score 23-13. With the win, the Bengals improved to 9-3 and secured only their third winning season in nineteen years .
How many more yards was the longest field goal compared with the shortest?

Passage: The Guatemalan authorities were unaware of ongoing contacts between the colonial authorities in Yucatán and the Itza. In the second half of 1695 President Barrios began planning another expedition against the Itza from Verapaz, following harsh criticism of Juan Díaz de Velasco's retreat from near Lake Petén Itzá in April of that year. Barrios died in November, and oidor José de Escals became acting head of the Guatemalan colonial administration. He appointed oidor Bartolomé de Amésqueta to lead the next expedition against the Itza. Amésqueta marched his men through torrential rain from Cahabón to Mopán, arriving on 25 February 1696; the Guatemalans were still unaware of the clashes between García's forces and the Itza. Amésqueta's expedition was suffering from shortages of native labour and supplies. Twenty-five of his 150 men were sick, and his advance stalled as the force rested up at Mopán. Captain Díaz de Velasco volunteered to lead a party of 25 men ahead to the lake; he was accompanied by Dominican friars Cristóbal de Prada and Jacinto de Vargas. He was also accompanied by AjK'ixaw, the Itza nobleman who had been taken prisoner on Díaz's previous expedition, who served as a trusted guide, scout and translator. They set out from Mopán on 7 March and left some sick soldiers with some supplies after five days, they then caught up with an advance party of roadbuilders and their military escort at Río Chakal. The two forces combined, giving Díaz a force of 49 soldiers and 34 porters and archers from Verapaz. Once they arrived at IxB'ol, near the shore of Lake Petén Itzá, AjK'ixaw was sent ahead as an emissary to Nojpetén.

How many contacts did the Guatemalan authorities not know about?
