Input: Question: Why was Adolf Eichmann arrested? Passage 1:In January 1996 former National Geographic photographer Charles O'Rear was on his way from his home in St. Helena, California, in the Napa Valley north of San Francisco, to visit his girlfriend, Daphne Irwin (whom he later married), in the city, as he did every Friday afternoon. He was working with Irwin on a book about the wine country. He was particularly alert for a photo opportunity that day, since a storm had just passed over and other recent winter rains had left the area especially green. Driving along the Sonoma Highway (California State Route 12 and 121) he saw the hill, free of the vineyards that normally covered the area; they had been pulled out a few years earlier following a phylloxera infestation. "There it was! My God, the grass is perfect! It's green! The sun is out; there's some clouds," he remembered thinking. He stopped somewhere near the Napa–Sonoma county line and pulled off the road to set his Mamiya RZ67 medium-format camera on a tripod, choosing Fujifilm's Velvia, a film often used among nature photographers and known to saturate some colors. O'Rear credits that combination of camera and film for the success of the image. "It made the difference and, I think, helped the 'Bliss' photograph stand out even more," he said. "I think that if I had shot it with 35 mm, it would not have nearly the same effect." While he was setting up his camera, he said it was possible that the clouds in the picture came in. "Everything was changing so quickly at that time." He took four shots and got back into his truck. According to O'Rear, the image was not digitally enhanced or manipulated in any way.
 Passage 2:In 1998, one week after winning E3 Harelbeke and the Brabantse Pijl in the same weekend, he won the Tour of Flanders, thereby equaling the race's record of three wins. One week later, Museeuw made a horrific fall in Paris–Roubaix on the Trouée d'Arenberg cobbled sector, leaving his kneeknap shattered. On top came a dangerous gangrene infection which nearly forced doctors to amputate his left leg. He fought back and resumed cycling after a long healing process, finishing third in the Tour of Flanders of 1999 and ninth in Paris–Roubaix, exactly one year after his horror crash. In 2000 he won Paris–Roubaix a second time after a 44 km solo. Upon crossing the finish line in victory, he lifted his left leg, pointing to his knee as a reminder of the injury that had almost ended his career two years before. Later that year, he was again injured in a motor cycle accident, causing a severe head trauma and several days in a coma. His dogged determination and powerful riding style won him legions of fans all over the world and made him all the more popular in his native Flanders.
 Passage 3:Rafael "Rafi" Eitan (; 23 November 1926 – 23 March 2019) was an Israeli politician and intelligence officer. He also led Gil and served as Minister of Senior Citizens. He was in charge of the Mossad operation that led to the arrest of Adolf Eichmann. He served as an advisor on terrorism to Prime Minister Menachem Begin, and in 1981 he was appointed to head the Bureau of Scientific Relations, then an intelligence entity on par with Mossad, Aman and Shabak. Eitan assumed responsibility for and resigned over the Jonathan Pollard affair, and the Bureau was disbanded. He was subject to an arrest warrant issued by the United States FBI. From 1985 until 1993, he was head of the government's Chemicals company, which was expanded under his leadership. After 1993, he became a businessman, noted for several large scale agricultural and construction ventures in Cuba. He was the chairman of the Vetek (Seniority) Association – the Senior Citizens Movement.
