Sentence Rearrangement or Para jumble is a part of the Verbal ability section(VA). It is slightly tricky because sentences can have multiple constructions but we have only one correct answer in the exam. Forming sentence pairs is the best approach. Always look out for the link between sentences and try to order them. This is a medium level difficulty question. The main theme is atomic energy and its repercussions. Go ahead, try out this question. To practice more such sentence arrangement questions, check out 2IIM's CAT Question Bank.
Question 19 : The four sentences (labelled A, B, C, D) 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:
A. But the attention of the layman, not surprisingly, has been captured by the atom bomb, although there is at least a chance that it may never be used again.
B. Of all the changes introduced by man into the household of nature, [controlled] large-scale nuclear fission is undoubtedly the most dangerous and most profound.
C. The danger to humanity created by the so-called peaceful uses of atomic energy may, however, be much greater.
D. The resultant ionizing radiation has become the most serious agent of pollution of the environment and the greatest threat to man’s survival on earth.
B is the best opening sentence. B states that large-scale nuclear fission is dangerous. D explains how so. So, BD is a sequence about the danger posed by large-scale nuclear fission. Statement A adds to BD, explaining that the attention of the layman, however, directed at the atom bomb instead. C talks of a danger that may be much greater: the danger to humanity by so-called "peaceful uses" of atomic energy. So, BDAC is the correct order.
