Input: Nutrition
In the early 20th century, Carl von Voit and Max Rubner independently measured caloric energy expenditure in different species of animals, applying principles of physics in nutrition. In 1906, Edith G. Willcock and Frederick Hopkins showed that the amino acid tryptophan aids the well-being of mice but it did not assure their growth. In the middle of twelve years of attempts to isolate them, Hopkins said in a 1906 lecture that "unsuspected dietetic factors," other than calories, protein, and minerals, are needed to prevent deficiency diseases. In 1907, Stephen M. Babcock and Edwin B. Hart conducted the single-grain experiment, which took nearly four years to complete.

What did Carl von Voit and Max Rubner apply to nutrition in order to receive their results?
Output: principles of physics

Input: Police
All police officers in the United Kingdom, whatever their actual rank, are 'constables' in terms of their legal position. This means that a newly appointed constable has the same arrest powers as a Chief Constable or Commissioner. However, certain higher ranks have additional powers to authorize certain aspects of police operations, such as a power to authorize a search of a suspect's house (section 18 PACE in England and Wales) by an officer of the rank of Inspector, or the power to authorize a suspect's detention beyond 24 hours by a Superintendent.

What powers of a new UK police officer are the same as a Commissioner's?
Output: arrest

Input: Biodiversity
Not all introduced species are invasive, nor all invasive species deliberately introduced. In cases such as the zebra mussel, invasion of US waterways was unintentional. In other cases, such as mongooses in Hawaii, the introduction is deliberate but ineffective (nocturnal rats were not vulnerable to the diurnal mongoose). In other cases, such as oil palms in Indonesia and Malaysia, the introduction produces substantial economic benefits, but the benefits are accompanied by costly unintended consequences.

What animal intentionally invaded Hawaii?
Output: mongooses

Input: Queen Victoria
Through the 1860s, Victoria relied increasingly on a manservant from Scotland, John Brown. Slanderous rumours of a romantic connection and even a secret marriage appeared in print, and the Queen was referred to as "Mrs. Brown". The story of their relationship was the subject of the 1997 movie Mrs. Brown. A painting by Sir Edwin Henry Landseer depicting the Queen with Brown was exhibited at the Royal Academy, and Victoria published a book, Leaves from the Journal of Our Life in the Highlands, which featured Brown prominently and in which the Queen praised him highly.

What country was Queen Victoria's manservant with whom she was rumored to have a romantic interest?
Output:
Scotland
