Question
[114]. Read the following passage carefully:
Passage: "Twice a day, the sea along many coasts rises and falls in a rhythm that fishermen know by heart. This rise and fall, called the tide, is caused mainly by the Moon's gravitational pull on the Earth's oceans, with the Sun adding a smaller pull. When the Moon is overhead, water bulges towards it, producing a high tide; when the Moon is elsewhere, the water spreads out and the level falls. Twice a month, when Sun, Moon and Earth line up, the pulls combine and tides grow higher, which fishermen call spring tides. Understanding tides matters for sailing, fishing and building harbours, because a boat that enters safely at high tide may strand at low tide." What is the main idea of the passage?
