Question

The five sentences (labelled 1, 2, 3, 4, 5) given in this question, when properly sequenced, form a coherent paragraph. Each sentence is labelled with a number. Decide on the proper order for the sentences and key in this sequence of five numbers as your answer.___

Answer 1

The entire passage is talking about diseases and dna from skeletons. All the sentences other than 5 have pronouns in them. Hence the sequence should start with sentence 5. We have introduced skeletons in 5. The next referral to it is in 4. So 54 is a mandatory pair. The analysis was introduced in 4. It is further referenced in 1. So 41 is another mandatory pair. Ages is referred in 3. The first reference to it is in 2. So 23 is a mandatory pair. Hence the sequence is 54123.
