QUESTION-30: 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.

1. The study suggests that the disease did not spread with such intensity, but that it may have driven human migrations across Europe and Asia.
2. The oldest sample came from an individual who lived in southeast Russia about 5,000 years ago.
3. The ages of the skeletons correspond to a time of mass exodus from today’s Russia and Ukraine into
Western Europe and Central Asia, suggesting that a pandemic could have driven these migrations.
4. In the analysis of fragments of DNA from 101 Bronze Age skeletons for sequences from Yersinia pestis, the bacterium that causes the disease, seven tested positive.
5. DNA from Bronze Age human skeletons indicate that the black plague could have emerged as early as 3,000 BCE, long before the epidemic that swept through Europe in the mid-1300s.

Answer: 54123
Explanation for the Question:

Statement 5 is the opening sentence in this case. It is the most generic sentence in the given set and introduces the topic that black plague emerged as early as 3,000 BCE.
Statement 4 then provides details about the study and what was the basic result.
Statement 1 takes this forward and explains more about the study.
Statement 2 tells us about the oldest sample and how it came from Russia. Statement 3 then explains the implications of the same and what does this imply with respect to the migration from Russia.
Thus, we have 54123 as the order in this case.
