You will be given a definition of a task first, then some input of the task.
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 tall is the highest point in the British Isles at above sea level? Passage 1:The 1924 World Series was the championship series of the 1924 Major League Baseball season. A best-of-seven playoff, the series was played between the American League (AL) pennant winner Washington Senators and the National League (NL) pennant winner New York Giants. The Senators defeated the Giants in seven games to win their first championship in club history. The Giants became the first team to play in four consecutive World Series, winning in 1921–1922 and losing in 1923–1924. Their long-time manager, John McGraw, made his ninth and final World Series appearance in 1924. The contest concluded with the second World Series-deciding game which ran to extra innings (the first had occurred in 1912). Later, the Senators would reorganize as the Minnesota Twins, again winning the World Series in 1987 and in 1991.
 Passage 2:The pair came to public attention when an Inverness-based fan sent their demo to the English band the Housemartins, who were impressed enough to invite the Proclaimers on their 1986 United Kingdom tour. The exposure of the tour won them a January 1987 appearance on the British pop music television programme The Tube on Channel Four; "Letter from America" peaked at number three in the UK Singles Chart, while the album This Is the Story went gold. The follow-up album Sunshine on Leith featured the singles "I'm Gonna Be (500 Miles)", which went to number one in Australia and New Zealand, and "I'm On My Way". They had a hit with their EP King of the Road, which reached number nine in the UK in 1990. "I'm Gonna Be (500 Miles)" belatedly peaked at number three on the Billboard Hot 100 in August 1993, after appearing in the movie Benny & Joon, becoming their only charted single in the United States. After seven low-profile years, they released their comeback album Persevere in 2001.
 Passage 3:The Grampian Mountains (Am Monadh in Gaelic) are one of the three major mountain ranges in Scotland, occupying a considerable portion of the Scottish Highlands in northern Scotland. The other major mountain ranges in Scotland are the Northwest Highlands and the Southern Uplands. The Grampian range extends southwest to northeast between the Highland Boundary Fault and the Great Glen, occupying almost half of the land area of Scotland and including the Cairngorms and the Lochaber hills. The range includes many of the highest mountains in the British Isles, including Ben Nevis (the highest point in the British Isles at above sea level) and Ben Macdui (the second highest at ).
