The four sentences (labelled 1, 2, 3 and 4) given below, when properly sequenced, would yield a coherent paragraph. Decide on the proper sequencing of the order of the sentences and key in the sequence of the four numbers as your answer.
1. What precisely are the “unusual elements” that make a particular case so attractive to a certain kind of audience?
2 . It might be a particularly savage or unfathomable level of depravity, very often it has something to do with the precise amount of mystery involved.
3. Unsolved, and perhaps unsolvable cases offer something that “ordinary” murder doesn’t.
4. Why are some crimes destined for perpetual re-examination and others locked into permanent obscurity?
Answer: 4123
Sentence 4 is the best opening sentence as it puts forward the question that why are some crimes examined more than other.
Sentence 1 should follow 4 as it carries on the question from sentence 4 and asks what are the element that make a case attractive.
Sentence 2 follows sentence 1 as it explores the 'unusual elements' mentioned in setence 1.
Sentence 3 concludes the paragraph stating that unsolved or unsolvable cases offer something that "ordinary" murder does not..
Hence, 4123.
