Yes, your answer is correct. Political borders, such as the border between Pakistan and India, are determined by governments and do not necessarily align with the ethnic, linguistic, or religious divisions within a region. Therefore, they may cut through cultural borders and communities. In the case of Pakistan and India, the partition in 1947 created political borders that separated communities who shared similar cultural, linguistic, and religious heritage, leading to significant social and cultural changes on both sides of the border.
