Teacher: Now, understand the problem? Solve this instance: Question: How tall is the second-highest point in the British Isles at above sea level? Passage: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 ).
