Given the task definition and input, reply with output. 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.

Question: How old was John Cabot when he left Portishead on the Matthew? Passage 1:The yellow bloodwood is found in central New South Wales from Howes Valley in the north to Tolwong in the south. Around the Sydney Basin, it is common on sandstone plateaux and escarpments in the vicinity of the Nepean and Hawkesbury Rivers, and lower Blue Mountains, particularly on western aspects of slopes. It is seen up to altitudes of 500 metres, with annual rainfall of 7301800mm. It grows in dry sclerophyll forest on sandstone soils, associated with such species as red bloodwood (Corymbia gummifera), dwarf apple (Angophora hispida), smooth-barked apple (Angophora costata), narrow-leaved stringybark (Eucalyptus sparsifolia), white stringybark (E. globoidea), sydney peppermint (E. piperita), grey gum (E. punctata), scribbly gums (E. haemastoma and E. racemosa) and black sheoak (Allocasuarina littoralis).
Passage 2:On December 1, 1981, United States President Ronald Reagan signed a presidential finding which authorized covert operations in Nicaragua. This plan initially called for the U.S. government to cooperate with the Argentinian government, which was already engaged in a similar operation, to train and fund an existing terrorist group in Nicaragua known as the Contras. The Contras also contributed to drug dealing in the US and brought a lot of crack cocaine. A reporter for the San Jose Mercury News proved the connection between the crack epidemic and the Contras. Initially the Contras were a group of republican guard members from the old Somoza regime ousted by the Sandinistas after the revolutionary conflict. Later, through the recruitment efforts of the CIA, the group became supplemented by mercenary guerrillas and was extensively trained by the CIA. Eventually, due to the U.S. alliance with Great Britain during the Falklands war, Argentina withdrew support for these programs and the CIA had to relocate their training sites to Honduras.
Passage 3:The town was built on the mouth of a small tributary of the Severn Estuary near the mouth of the River Avon. The old pill or jetty provided protection for craft against the Bristol Channel's large tidal range, and iron rings can be seen in the high street at which fishing boats used to moor. Its position meant Portishead was used to guard the "King Road", as the waters around the headland are called. In 1497 it was the departure point for John Cabot on the Matthew. A fort was built on Battery Point, and was used during the English Civil War when the town supported the Royalists, but surrendered to Fairfax in 1645. Guns were also placed at Battery Point during World War II. The King Road was the site of a naval action in 1758 when HMS Antelope captured HMS Belliqueux, one of a French squadron returning from Quebec.
