Unseen Prose Passages — quick quiz

Read the passage and answer the question. The Indian monsoon is one of the most remarkable weather phenomena on Earth. Every year, between June and September, warm, moist winds sweep across the Indian subcontinent, bringing life-giving rains to millions of farmers. The monsoon does not arrive uniformly; it first reaches the Kerala coast around June 1st, then gradually advances northward. By mid-July, most of India receives rainfall. The monsoon is critical for agriculture, as nearly 60% of India's farmland depends on it. A delayed or weak monsoon can lead to drought, affecting food production and the rural economy. Conversely, excessive rainfall can cause floods and damage crops. Scientists use satellite data and computer models to predict the monsoon's arrival and intensity, helping farmers plan their sowing season. Question: What is the main idea of the passage?
