Concept:The passage must be arranged in a logical chronological and causal sequence from a general transformation to a specific treaty and its aftermath.
Explanation:S1 states that eighteenth-century Europe underwent transformation in many areas.
Sentence Q directly reinforces this by noting that the century produced enduring changes, so Q follows S1.
Next, sentence S introduces the Treaty of Paris (1763) which ended the Seven Years War, a concrete historical event.
Sentence P then describes the result: Europe remained free from major conflict for about thirty years after that treaty.
