Teacher: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.
Teacher: Now, understand the problem? Solve this instance: Passage: The Genoese held the colony of Galata on the Golden Horn across from the city of Constantinople since 1261 as part of the Treaty of Nymphaeum, a trade agreement between the Byzantines and Genoese. However, the dilapidated state of the Byzantine Empire following the civil war of 1341-1347 was easily shown in the control of custom duties through the strategic straights of the Bosphorus. Even though Constantinople was the Imperial seat of power with its cultural and military center on the shores of the Bosphorus, only thirteen percent of custom dues passing through the strait were going to the Empire. The remaining 87 percent was collected by the Genoese from their colony of Galata. Genoa collected 200,000 hyperpyra from annual custom revenues from Galata, while Constantinople collected a mere 30,000. The Byzantine navy, a notable force in the Aegean during the reign of Andronikos III Palaiologos, was completely destroyed during the civil war. Thrace, the main imperial possession besides the Despotate of the Morea, was still recovering following the destruction of marauding Turkish mercenaries during the civil war. Byzantine trade was ruined and there were few other financial reserves for the Empire other than the duties and tariffs from the Bosphorus.
Student:
How many more collection of 200,000 hyperpyra did Genoa collect than 30,000 hyperpyra for Constantinople?
