To form a logical sequence, we start with the fixed first sentence: "Among the chief sources of education available to Tagore was a quiet garden adjoining his family house" (I). - Sentence II follows logically as it explains that the garden was where Tagore came to understand the principle of harmony. - Sentence V follows naturally, describing how his early contact with nature shaped his mood and mindset. - Sentence III logically follows V, as it explains how Tagore spent much of his time in the garden absorbing the peace of nature. - Finally, Sentence IV fits in the sequence, showing that during this time, Tagore developed the habit of observing and reflecting on his surroundings. Thus, the correct sequence is: II - V - III - IV. Therefore, the correct answer is option (2).
