Concept:The sentence parts must be rearranged to form a grammatically correct and logical sequence.
Explanation:Start by identifying the opening part. Q introduces the main idea: "there are many ways of dealing".
The verb "dealing" is typically followed by "with", so S must come next: "with intransigent customers".
Next, P provides a contrasting suggestion: "but perhaps the best way is to agree".
Finally, R completes the thought: "with them without excessive argumentation".
Thus, the correct order is Q, S, P, R.
All other options break the logical flow or grammatical pairing.
