The question below consists of a set of labelled sentences. Out of the four options given, select the most logical order of the sentences to form a coherent paragraph. P. The longer a group of animals remains in one place, the more mutations they accumulate, increasing their genetic diversity. Q. Scientists determined the chipmunks’ migration routes by analyzing mutations in their genes. R. DNA samples from more than 200 chipmunks in Illinois and Wisconsin were used to construct a family tree showing that chipmunks migrated further south only after glaciers receded. S. Chipmunks recently challenged the scientific dogma that small mammals were forced south during the Ice Age 18,000 years ago.

The correct answer is option 3.
Sentence 1- The first sentence should always introduce the subject matter of the paragraph to the reader. In this case, sentence S introduces the topic i.e, the theory of chipmunks being forced south during the Ice Age has been challenged.
Sentence 2- Sentence R is a continuation of sentence S. It says that DNA samples have been collected to prove that chipmunks migrated only after glaciers receded.
Sentence 3- Sentence Q takes the research work further. It says that scientists have determined the migration routes of the chipmunks by analyzing mutations in their genes.
Sentence 4- The last sentence always concludes the paragraph and confirms the statement made in the paragraph. Sentence P makes the point about the diversity in the mutations of chipmunks even stronger.
Therefore, the correct order is SRQP.
