Q1
Which of the following options is the best logical order of the above statements?
Answer: B
Since all the sentences except 2 use “here” and “this” referring to the subject of the paragraph, we can assume that sentence 2 introduces the subject of discussion. Thus, options 1, 4 and 5 can be eliminated. Sentence 3 follows as it describes the Caucasus range in detail. Sentences 3-1 form a link as 3 mentions “a six-hundred-mile chain of mountains” and 1 refers to these mountains. Further, sentences 4-5 in that order conclude the paragraph.
Hence, the correct answer is option 2.
