‘Q’ will be the first part of the given sequence as it talks about the coming of science with relation to the statement made in S1. It will be followed by ‘S’ as the pronoun ‘it’ refers to the ‘Church’ in Q. RP will make a pair together as the expression ‘as a result of this’ is used in the context of the statement made in ‘R’. Hence, QSRP is the right sequence. Thus, option (b) is correct.
