Why this is the correct answer

West Germany signed its first bilateral labor recruitment agreement with Italy in December 1955, making Italians the first officially recruited guest workers. Agreements with Spain, Portugal, and Turkey came in later years, but Italy holds the historical distinction as the first country from which Gastarbeiter were recruited.
