Input: Article: Early recommendations for the quantity of water required for maintenance of good health suggested that 6–8 glasses of water daily is the minimum to maintain proper hydration. However the notion that a person should consume eight glasses of water per day cannot be traced to a credible scientific source. The original water intake recommendation in 1945 by the Food and Nutrition Board of the National Research Council read: "An ordinary standard for diverse persons is 1 milliliter for each calorie of food. Most of this quantity is contained in prepared foods." More recent comparisons of well-known recommendations on fluid intake have revealed large discrepancies in the volumes of water we need to consume for good health. Therefore, to help standardize guidelines, recommendations for water consumption are included in two recent European Food Safety Authority (EFSA) documents (2010): (i) Food-based dietary guidelines and (ii) Dietary reference values for water or adequate daily intakes (ADI). These specifications were provided by calculating adequate intakes from measured intakes in populations of individuals with “desirable osmolarity values of urine and desirable water volumes per energy unit consumed.” For healthful hydration, the current EFSA guidelines recommend total water intakes of 2.0 L/day for adult females and 2.5 L/day for adult males. These reference values include water from drinking water, other beverages, and from food. About 80% of our daily water requirement comes from the beverages we drink, with the remaining 20% coming from food. Water content varies depending on the type of food consumed, with fruit and vegetables containing more than cereals, for example. These values are estimated using country-specific food balance sheets published by the Food and Agriculture Organisation of the United Nations. Other guidelines for nutrition also have implications for the beverages we consume for healthy hydration- for example, the World Health Organization (WHO) recommend that added sugars should represent no more than 10% of total energy intake.

Now answer this question: How much water should be taken in for each calorie of food that is consumed?

Output: 1 milliliter

Input: Article: In the Mexico City airport, the government engaged in an extensive restructuring program that includes the addition of a new second terminal, which began operations in 2007, and the enlargement of four other airports (at the nearby cities of Toluca, Querétaro, Puebla and Cuernavaca) that, along with Mexico City's airport, comprise the Grupo Aeroportuario del Valle de México, distributing traffic to different regions in Mexico. The city of Pachuca will also provide additional expansion to central Mexico's airport network. Mexico City's airport is the main hub for 11 of the 21 national airline companies.

Now answer this question: How many national airlines are there in Mexico?

Output: 21

Input: Article: Almost 60 years later, 80 year old career criminal Henry (Harry) James Burge claimed to have committed the theft, confessing to a newspaper, with the story being published in the Sunday Pictorial newspaper on 23 February 1958. He claimed to have carried out the robbery with two other men, although when discrepancies with a contemporaneous report in the Birmingham Post newspaper (the crime pre-dated written police reports) in his account of the means of entry and other items stolen, detectives decided there was no realistic possibility of a conviction and the case was closed. Burge claimed the cup had been melted down to make counterfeit half-crown coins, which matched known intelligence of the time, in which stolen silver was being used to forge coins which were then laundered through betting shops at a local racecourse, although Burge had no past history of forgery in a record of 42 previous convictions for which he had spent 42 years in prison. He had been further imprisoned in 1957 for seven years for theft from cars. Released in 1961, he died in 1964.

Now answer this question: What did they do with those coins? 

Output:
stolen silver was being used to forge coins which were then laundered through betting shops at a local racecourse
