Question
In each of the questions given below, four
words are given in bold. These four words may or may not be in their correct position. The sentence is then followed by options with the correct combination of words that should replace each other in order to make the sentence grammatically and contextually correct. Find the correct combination of words that replace each other. If the sentence is correct as it is, select ā5ā as your option. AsĀ newĀ societalĀ challengesĀ like theĀ public (A) Ā crisisĀ andĀ agency (B) beliefsĀ emerged,Ā theĀ DSTĀ formed anĀ superstitious (C)Ā toĀ promote energy (D) debateĀ onĀ scienceĀ andĀ technology.Solution
A - D: The original sentence had "public crisis" in part A, and I changed it to "energy" to improve the coherence and context of the sentence. It makes more sense in the context of a debate on science and technology. B - C: The original sentence had "agency beliefs" in part B, and I changed it to "superstitious" for better grammatical structure and meaning. The phrase "superstitious to promote energy" doesn't make sense, so this change enhances the sentence's clarity and logic. The corrected sentence conveys that the DST (Department of Science and Technology) formed a committee or initiative to promote a debate on science and technology in response to emerging societal challenges such as public crises and agency beliefs.
