Concept:This question tests the ability to arrange jumbled sentence parts into a logical and grammatically correct order.

Part Q follows logically, introducing the observation: “one could not overlook the diminishing religiosity which”.
Part P then explains the effect: “was gradually engulfing the society with its concomitant”.
Part S completes the sentence by adding the time frame: “implication for the stage from the third decade of the twentieth century”.
Thus the sequence R → Q → P → S forms a coherent sentence.
Answer:The correct sequence is RQPS, which corresponds to option (b).
