Her long-standing boyfriend left her at this time. The depression was so severe it lasted for a couple of years, during which she occasionally kept herself in her bedroom for days and refused to eat anything.

Beyonce would later speak of her mother as the person who helped her fight it. Franklin was dismissed, leaving just Beyonce, Rowland, and Williams.
Question: Who helped Beyonce fight her depression the most?

Input: Read this: In Du "Cubisme" Metzinger and Gleizes explicitly related the sense of time to multiple perspective, giving symbolic expression to the notion of 'duration' proposed by the philosopher Henri Bergson according to which life is subjectively experienced as a continuum, with the past flowing into the present and the present merging into the future. The Salon Cubists used the faceted treatment of solid and space and effects of multiple viewpoints to convey a physical and psychological sense of the fluidity of consciousness, blurring the distinctions between past, present and future. One of the major theoretical innovations made by the Salon Cubists, independently of Picasso and Braque, was that of simultaneity, drawing to greater or lesser extent on theories of Henri Poincare, Ernst Mach, Charles Henry, Maurice Princet, and Henri Bergson. With simultaneity, the concept of separate spatial and temporal dimensions was comprehensively challenged. Linear perspective developed during the Renaissance was vacated. The subject matter was no longer considered from a specific point of view at a moment in time, but built following a selection of successive viewpoints, i.e., as if viewed simultaneously from numerous angles (and in multiple dimensions) with the eye free to roam from one to the other.
Question: What type of philosopher was Henri Bergson?

Output: unanswerable

Input: Read this: A cappella [a kapplla] (Italian for "in the manner of the chapel") music is specifically group or solo singing without instrumental accompaniment, or a piece intended to be performed in this way. It contrasts with cantata, which is accompanied singing. The term "a cappella" was originally intended to differentiate between Renaissance polyphony and Baroque concertato style. In the 19th century a renewed interest in Renaissance polyphony coupled with an ignorance of the fact that vocal parts were often doubled by instrumentalists led to the term coming to mean unaccompanied vocal music. The term is also used, albeit rarely, as a synonym for alla breve.
Question: What is a synonym for cantata?

Output: unanswerable

Input: Read this: Partly because of low sanitation coverage about 17,000 children die each year because of diarrhoea. Another challenge is low cost recovery due to water tariffs that are among the lowest in the world. This in turn requires government subsidies even for operating costs, a situation that has been aggravated by salary increases without tariff increases after the Arab Spring. Poor operation of facilities, such as water and wastewater treatment plants, as well as limited government accountability and transparency, are also issues.
Question: Due to low waer tariffs, what is required to maintain water treatment operation?

Output:
government subsidies
