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 flagship red variety of Tabasco pepper sauce measures 2,500–5,000 SHU on the Scoville scale. The habanero sauce is considerably hotter, rating above 7,000+ Scoville units. The chipotle sauce adds chipotle pepper to the original sauce, measuring 1,500–2,500. The garlic variety, which blends milder peppers in with the tabasco peppers, rates 1,200–1,400 Scovilles, and the green pepper (jalapeño) sauce is even milder at 600–1,200 Scovilles. The Sweet and Spicy sauce is the mildest of all the sauces at only 100–600 Scoville units. In 2017, Tabasco released a limited edition sauce made with the Trinidad Moruga Scorpion pepper, which can reach up to 2,000,000 scoville units.

A: How many Tabasco sauces exist that can reach up to 2,000,000 scoville units?

Q: Passage: New Caledonia is a major source for nickel and contains roughly 10% of the worlds known nickel supply. The islands contain about 7,100,000 tonnes of nickel. With the annual production of about 107,000 tonnes in 2009, New Caledonia was the Nickel mining in New Caledonia after Russia (266,000), Indonesia (189,000), Canada (181,000) and Australia (167,000). In recent years, the economy has suffered because of depressed international demand for nickel, due to the ongoing financial crisis of 2007–2008. Only a negligible amount of the land is suitable for cultivation, and food accounts for about 20% of imports. In addition to nickel, the substantial financial support from France and tourism are keys to the health of the economy. In the 2000s, large additions were made to nickel mining capacity. The Goro, New Caledonia is expected to be one of the largest nickel producing plants on Earth. When full-scale production begins in 2013 this plant will produce an estimated 20% of the global nickel supply. However, the need to respond to environmental concerns over the countrys globally recognized ecological heritage, may increasingly need to be factored into capitalization of mining operations.

A: How many countries rank above New Caledonia in nickel supply?

Q: Passage: The squadron of Vasco da Gama left Portugal in 1497, rounded the Cape and continued along the coast of East Africa, where a local pilot was brought on board who guided them across the Indian Ocean, reaching Calicut in western India in May 1498. The second voyage to India was dispatched in 1500 under Pedro Álvares Cabral. While following the same south-westerly route as Gama across the Atlantic Ocean, Cabral made landfall on the Brazilian coast. This was probably an accidental discovery, but it has been speculated that the Portuguese secretly knew of Brazil's existence and that it lay on their side of the Tordesillas line. Cabral recommended to the Portuguese King that the land be settled, and two follow up voyages were sent in 1501 and 1503. The land was found to be abundant in pau-brasil, or brazilwood, from which it later inherited its name, but the failure to find gold or silver meant that for the time being Portuguese efforts were concentrated on India. On 8 July 1497 the fleet, consisting of four ships and a crew of 170 men, left Lisbon The travel led by Vasco da Gama to Calicut was the starting point for deployment of Portuguese in the African east coast and in the Indian Ocean. The first contact occurred on 20 May 1498. After some conflict, he got an ambiguous letter for trade with the Zamorin of Calicut, leaving there some men to establish a trading post. Since then explorations lost the private nature, taking place under the exclusive of the Portuguese Crown. Shortly after, the Casa da Índia was established in Lisbon to administer the royal monopoly of navigation and trade.

A:
How many days passed between the fleet leaving Libon and them making first contact?
