premise: Foals are an English indie rock band from Oxford, England formed in 2005, consisting of lead vocalist and lead guitarist Yannis Philippakis, drummer and percussionist Jack Bevan, rhythm guitarist Jimmy Smith, bassist Walter Gervers, and keyboardist Edwin Congreave. Since the band's formation, their line-up has remained constant, except for the departure of former lead singer Andrew Mears.
hypothesis: Yannis Philippakis was born in nineteen hundred seventy five.
reason: His year of birth is never mentioned and 1975 is a reasonable year based on when the band was formed. It's difficult because I wrote out the year in words.
