[Done] Q1. Read the following passage carefully and answer the questions: Arun had always lived in the noisy city, surrounded by tall buildings and crowded streets. One summer, he visited his grandparents who lived in a quiet village. Behind their old cottage was a gate covered in vines. Curious, Arun pushed it open and discovered a hidden garden. It was overgrown, yet beautiful — filled with wildflowers, buzzing bees, and a small fountain that still trickled water. Every day, Arun would sneak out to the garden. He pulled weeds, watered plants, and watched butterflies flutter from flower to flower. Slowly, the garden began to bloom again. Arun felt peaceful there, far from the noise of the city. For the first time, he felt connected to nature. When it was time to leave, he promised his grandparents he would return the next summer to care for the garden. 1.
