Arrange the parts to form a meaningful sentence: P: are evolving rapidly / Q: the geo-political and geo-economic landscape / R: where aspects related to application of military force / S: in a multipolar world is dynamic

The complete sentence reads: 'The geo-political and geo-economic landscape (Q) in a multipolar world is dynamic (S) where aspects related to application of military force (R) are evolving rapidly (P).' Q introduces the subject 'landscape', S describes it as 'dynamic in a multipolar world', R provides the relative clause about aspects, and P completes with the verb describing the evolution. Hence, the correct sequence is QSRP.
