In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
Q: Question: Who was in charge of the NIH the year Fanon went to the US for cancer treatment? Passage 1:Upon his return to Tunis, after his exhausting trip across the Sahara to open a Third Front, Fanon was diagnosed with leukemia. He went to the Soviet Union for treatment and experienced some remission of his illness. When he came back to Tunis once again, he dictated his testament The Wretched of the Earth. When he was not confined to his bed, he delivered lectures to Armée de Libération Nationale (ALN) officers at Ghardimao on the Algero-Tunisian border. He made a final visit to Sartre in Rome. In 1961, the CIA arranged a trip to the U.S. for further leukemia treatment at a National Institutes of Health facility. During his time in the United States, Fanon was handled by CIA agent Oliver Iselin.
 Passage 2:Most versions of "Bottle Up and Go" recorded after Tommy McClennan's single use a combination of his verses and new lyrics. Early versions (often with a variation on the title) include those by Blind Boy Fuller (as "Step It Up and Go") (1940), Lead Belly (1940), and Sonny Terry and Brownie McGhee (1942). Western swing band Maddox Brothers and Rose recorded it as "New Step It Up and Go" (1951). B.B. King recorded a version as "Shake It Up and Go" (1952) "although he confuses himself by saying 'bottle up and go' half the time". He later re-recorded it for the Blues on the Bayou album (1998). The Everly Brothers included it as "Step It Up and Go" for Instant Party! (1962) and The Everly Brothers Reunion Concert (1983). Bob Dylan recorded "Step It Up and Go" for Good as I Been to You (1992). The song has also been regularly featured by Mungo Jerry in their live performances. It has been suggested that Chuck Berry's "Too Much Monkey Business" is adapted from McClennan's song.
 Passage 3:The history of Lubartów begins on May 29, 1543, when King Sigismund the Old allowed local nobleman Piotr Firlej to found a town called Lewartów (the original name comes from Lewart, the coat of arms of the Firlej family). The town became famous when it belonged to Mikołaj Firlej, the son of Piotr Firlej. In the late 16th century, it was one of centers of Calvinism in Lesser Poland, and Mikołaj Firlej invited here a number of skilled artisans from France, Germany and Holland, as well as cattle breeders. Lewartów frequently changed owners. In the early 18th century it belonged to the Sanguszko family, who rebuilt the palace, built two Baroque churches and tenement houses. Upon request of Paweł Karol Sanguszko, on November 22, 1744, King Augustus III of Poland changed the name of the town to Lubartów (in honor of Lubart - Liubartas, the son of Lithuanian Prince Gediminas; Sanguszko believed that Liubartas was the founder of his family). King Augustus granted a new coat of arms to the town. The 19th century was not lucky for Lubartów, as the town, which from 1815 to 1915 belonged to Russian-controlled Congress Poland, burned several times (1831, 1838, 1846). In 1866 it became the seat of a county, and slowly began modernization. By 1912 it had seven manufacturing enterprises, including mills and a brewery, in 1922, glassworks were opened.
