The question asks why Simran started studying again at the end. From the story context, Simran initially thought that bees, birds, and trees had easier lives. However, after talking to each of them, she realized that everyone works hard - bees fly all day collecting nectar, birds search for food and build nests, and trees work day and night through their roots and leaves. This made her understand that 'परिश्रम से ही सब जीतें हैं' (everyone wins through hard work). She decided to embrace hard work herself and study with dedication ('मन लगाकर पढ़ना चाहिए').
