Task: Question Answering
Input (English): Passage: Johnny, played by Johnny Solo, pulls over at the end of his shift as a New York City taxi driver. Suddenly, it's quiet, he's alone and the reality of his miserable life starts to surface. It's obvious in his face and the look in his eyes that he is depressed, on edge and seeking an escape—an escape he hopes to achieve by his dependency on drugs and alcohol. That night's drug purchase doesn't go as planned as he finds himself at the mercy of his drug dealer.
Johnny's inner demons as well as his father's financial dependency on him overwhelms him. He's back in his taxi and about to act on negative impulses. Suddenly, he's interrupted by a hard knock on the driver's side window. Lily, played by 2X BAFTA nominated actress, Lelia Goldoni, had her acting debut by being nominated for the BAFTA Award for Most Promising Newcomer to Leading Film Roles at the Venice Film Festival by acting in John Cassavetes feature film Shadows (1959 film).Lily stands outside in the freezing cold weather insisting on a ride home. Barely rolling down his window and after some persuasion, Johnny reluctantly agrees to drive her, for a price. What follows is an unexpected journey. 
Question: What does the man whose window gets knocked on do for a living?
Output (English): taxi driver.
