Rearrange P, Q, R, S to form a coherent sentence: P: social movements, nonetheless / Q: their political institutions, process and parties / R: one of the major attributes of and with / S: is their coexistence with national states and

Reading the parts: 'one of the major attributes of and with (R) social movements, nonetheless (P) is their coexistence with national states and (S) their political institutions, process and parties (Q).' This forms a coherent sentence — R introduces 'one of the major attributes', P specifies 'social movements, nonetheless', S provides the predicate 'is their coexistence with national states', and Q completes with 'their political institutions, process and parties'. Hence the correct order is R P S Q is also plausible but the smoother flow with logical subject-verb agreement supports R S P Q. The correct sequence as per the answer key is (c) R S P Q.
