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.

Q: Passage: The U.S. Institute of Medicine (IOM) updated Estimated Average Requirements (EARs) and Recommended Dietary Allowances (RDAs) for iron in 2001. The current EAR for iron for women ages 14–18 is 7.9 mg/day, 8.1 for ages 19–50 and 5.0 thereafter (post menopause). For men the EAR is 6.0 mg/day for ages 19 and up. The RDA is 15.0 mg/day for women ages 15–18, 18.0 for 19–50 and 8.0 thereafter. For men, 8.0 mg/day for ages 19 and up. RDAs are higher than EARs so as to identify amounts that will cover people with higher than average requirements. RDA for pregnancy is 27 mg/day and, for lactation, 9 mg/day. For children ages 1–3 years 7 mg/day, 10 for ages 4–8 and 8 for ages 9–13. As for safety, the IOM also sets Tolerable upper intake levels (ULs) for vitamins and minerals when evidence is sufficient. In the case of iron the UL is set at 45 mg/day. Collectively the EARs, RDAs and ULs are referred to as Dietary Reference Intakes.

A: How many mg higher is the RDA for women aged 19-50 than for men 19 and older?

Q: Passage: In the meantime Flanders was again at war with the Count of Holland. John II, Count of Holland since 1299, also ruled over the County of Hainaut and the County of Zeeland, and was part of the House of Avesnes, the hereditary enemy of the Flemish House of Dampierre. Zealand had been contested between the Count of Flanders and the Count of Holland since the early 11th century and had become part of Holland by 1076. The Flemish invaded Hainaut in 1302 and conquered Lessines. Guy of Namur, son of the Count of Flanders, formed a fleet at Sluis and sailed on 23 April 1303 to claim Zeeland for the Flemish. After some initial successes, Guy was defeated on 10 and 11 August 1304 in the Battle of Zierikzee by a combined Franco-Hollandic fleet under Rainier Grimaldi, who had been sent by Philip IV of France to aid the Count of Holland. Guy of Namur was captured and Zeeland remained firmly in the hands of the Count of Holland. One week after this naval battle, on 18 August Philip IV himself fought the Flemish main army at the Battle of Mons-en-Pévèle. This hard fought battle was inconclusive, but the death of William of Jülich and the serious material losses of the Flemish, made them sue for peace. After further minor battles, eventually the Treaty of Athis-sur-Orge was signed on 23 June 1305 which recognized Flemish independence, but at the cost of the cities of Lille, Douai and Orchies, which were transferred to France, and the paying of exorbitant fines to King Philip IV.

A: How many cities did the Flemish lose as a result of signing the Treaty of Athis-sur-Ogre?

Q: Passage: At the same time the Baku Commune was involved in heavy fighting with the advancing Caucasian Ottoman Army in and around Ganja. The Ottoman Empire's Enver Pasha began to move forward with the newly established Army of Islam. Major battles occurred in Yevlakh and Agdash. Dunsterville ordered the evacuation of the city on September 14, after six weeks of occupation, and withdrew to Iran; most of the Armenian population escaped with British forces. The Ottoman Army of Islam and its Azeri allies, led by Nuri Pasha, entered Baku on September 15 and slaughtered between 10,000-20,000 Armenians in retaliation for the March massacre of Muslims. The capital of the Azerbaijan was finally moved from Ganja to Baku. However, after the Armistice of Mudros between the United Kingdom and the Ottoman Empire on October 30, Turkish troops were substituted by the Triple Entente. Headed by British Gen. W. Thomson, who had declared himself the military governor of Baku, 1,000 Commonwealth soldiers arrived in Baku on November 17, 1918. By Gen. Thomson's order, martial law was implemented in Baku.

A:
How many days after Dunsterville ordered the evacuation of the city did the Ottoman Army of Islam and its Azeri allies enter Baku?
