Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.
One example: Context: Architecturally, the school has a Catholic character. Atop the Main Building's gold dome is a golden statue of the Virgin Mary. Immediately in front of the Main Building and facing it, is a copper statue of Christ with arms upraised with the legend 'Venite Ad Me Omnes'. Next to the Main Building is the Basilica of the Sacred Heart. Immediately behind the basilica is the Grotto, a Marian place of prayer and reflection. It is a replica of the grotto at Lourdes, France where the Virgin Mary reputedly appeared to Saint Bernadette Soubirous in 1858. At the end of the main drive (and in a direct line that connects through 3 statues and the Gold Dome), is a simple, modern stone statue of Mary.
Question: To whom did the Virgin Mary allegedly appear in 1858 in Lourdes France?
Solution is here: Saint Bernadette Soubirous
Explanation: This is the correct answer. Because the question is asking for the name of the person and following sentence from the passage answers it: It is a replica of the grotto at Lourdes, France where the Virgin Mary reputedly appeared to Saint Bernadette Soubirous in 1858.

Now, solve this: Context: When he was still a child, Iwatake's father was lost at sea off Hawaii. With no food, his family was forced to move to Japan, where Iwatake joined the army during the war. He lost a brother when the bomb fell on Hiroshima. But over all the time one thing has remained unchanged. His parents bought a Christmas tree in 1937, and his family brings it out every Christmas since then, even when doing so meat risking arrest. "This tree was a shining light, because it was a symbol of unity in my family," Iwatake said as he and his wife put the final touches on the tree, which is about 3 - foot - tall. They took it out once again this year, "We have put this tree up every year for 70 years." Though he considers himself Buddhist, Iwatake was raised in a Christian tradition. He still keeps a photo of the tiny wooden church in Mauri where he and his five brothers went to church services and Sunday school. Christmas was always a special time. His father worked at a store, and Iwatake remembers the day he came home with a tree. It was nothing all that special, just metal - and - plastic, the kind of decoration that can easily be placed on a table, or in a corner somewhere. He got a string of lights, too, the kind with the big bulbs . Soon after, his father died in a fishing accident. His body was never found. Iwatake's mother had s in Japan, and took Iwatake's younger brothers there. Iwatake stayed behind to graduate from high school. In 1941, six months before Pearl Harbor , he moved to Japan as well. "Things were bad," he said. "There were war clouds hanging everywhere."
Question: What caused the death of Iwatake's father?
Solution:
an accident.
