Arrange the sentence in their correct order. A. Mr Raman's personality sets…

Correct order: 'Mr Raman's personality sets him apart from the rest' → 'He has a fanatical devotion to detail' → 'Nothing is too small for his attention' → 'This is what makes him a different guy.'

• Start with the introductory sentence: 'Mr Raman's personality sets him apart from the rest.' This identifies the subject and signals that what follows will explain why he is different.

• Follow with the explanatory sentence: 'He has a fanatical devotion to detail.' This states the specific trait that distinguishes him.

• Next, place the elaboration: 'Nothing is too small for his attention.' This sentence expands on the devotion to detail just described.

• Conclude with the summarizing sentence: 'This is what makes him a different guy.' The word 'this' clearly refers to the devotion and attention to detail explained in the previous sentences.

Because of the dependency of the elaborating and concluding sentences on the initial introduction and explanation, the coherent sequence is the four sentences in the order shown above.
