In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

[EX Q]: Who found that physical action cannot take on an arbitrary value?, Context: Classical statistical mechanics requires the existence of h (but does not define its value). Eventually, following upon Planck's discovery, it was recognized that physical action cannot take on an arbitrary value. Instead, it must be some multiple of a very small quantity, the "quantum of action", now called the Planck constant. Classical physics cannot explain this fact. In many cases, such as for monochromatic light or for atoms, this quantum of action also implies that only certain energy levels are allowed, and values in between are forbidden.
[EX A]: Planck

[EX Q]: Which acronym is the shortest among ANSI, IESNA and ASHRAE?, Context: The Illuminating Engineering Society of North America (IESNA), in conjunction with organizations like ANSI and ASHRAE, publishes guidelines, standards, and handbooks that allow categorization of the illumination needs of different built environments. Manufacturers of lighting equipment publish photometric data for their products, which defines the distribution of light released by a specific luminaire. This data is typically expressed in standardized form defined by the IESNA.
[EX A]: ANSI

[EX Q]: What form of French is spoken by a small minority of St. Bartholomese people of the leeward region?, Context: Residents of Saint-Barthélemy (Saint-Barthélemoise people) are French citizens and work at establishments on the island. Most of them are descendants of the first settlers, of Breton, Norman, Poitevin, Saintongeais and Angevin lineage. French is the native tongue of the population. English is understood in hotels and restaurants, and a small population of Anglophones have been resident in Gustavia for many years. The St. Barthélemy French patois is spoken by some 500–700 people in the leeward portion of the island and is superficially related to Quebec French, whereas Créole French is limited to the windward side. Unlike other populations in the Caribbean, language preference between the Créole and Patois is geographically, and not racially, determined.[page needed]
