Rearrange P, Q, R, S to form a coherent sentence: P: the opportunities to the greater triumphs / Q: today are but a step towards / R: the achievements we celebrate / S: and achievements that await us

Reading the parts: 'the achievements we celebrate (R) today are but a step towards (Q) the opportunities to the greater triumphs (P) and achievements that await us (S).' This forms a coherent, inspirational sentence. R introduces the subject ('the achievements we celebrate'), Q provides the verb phrase ('today are but a step towards'), P completes the object ('the opportunities to greater triumphs'), and S concludes with 'and achievements that await us'. Hence the correct order is R Q P S, option (d).
