‘S’ will be the first part of the given sequence as it begins with the word 'that' which indicates that this sentence talks about the poem and stories mentioned in the previous one. 'Q' will come next as it tells us the reason for 'S'. 'P' will come next as it tells about the next action and 'R' will follow logically with 'P' to complete the description. Hence, SQPR becomes the right sequence of words. Hence, option (a) is correct.
