Task: Question Answering
Input (English): Passage: Hirata is a successful Japanese businessman whose plan for a two-week winter holiday in Hawaii to play golf changes when his elderly grandfather reminds him that he should go to Iceland.
Hirata's parents died there seven years ago, and the seven year death anniversary is a significant event in Japanese culture. Hirata must perform a ceremony in the river where they died after drowning in an avalanche – the drowned must be fed by the surviving family members if they are to find peace.
Hirata goes to Iceland – to Reykjavík. His final destination is a remote river on the far side of the island. He encounters one mishap and misadventure after another. He first accidentally gets on a wrong bus filled with German tourists traveling to see the hot springs. He also confronts a language barrier; Hirata cannot speak any Icelandic, and knows very little English. After his first day's misadventures, Hirata decides to purchase an ancient, bright red Citroën DS to make the journey. During the long drive, Hirata meets several strange people along the way. These include the mystical woman who sells him the car, that only plays one radio station. Next, Hirata meets a local woman who collects photographs of funerals. The following day, Hirata meets two American hitchhiker/fugitives (Lili Taylor and Fisher Stevens), who turn out to be armed and dangerous who proceed to steal his car. Nearing his destination on foot, Hirata arrives in a small village where he meets an old man named Siggi, the owner of a local lodge who teaches Hirata how to drink the most potent alcoholic beverage in Iceland. 
Question: Whose car did the car thieves take?
Output (English): Hirata.
