Question
Column (1) Column (2) (A) Maths explains the phenomenon of strings vibrating (D) with their strings in a mathematical note. (B) Instruments like the cello have a particular shape to resonate (E) with a rocket to overcome earth’s gravitational pull. (C) Calculus guides scientists to calculate the speed required (F) at certain frequencies to create sound waves. In the following questions, two columns are given, Column 1 and Column 2. Each column contains 3 phrases. Match the phrases in Column 1 with the phrases in Column 2, so that they form grammatically and contextually correct sentences. If no such statements can be formed, choose option 5, “None of these” as your answer.
Solution
A-D does not make any sense. B-E is incorrect. Cello and rocket do not have anything to do with each other. C-D is incorrect because the preposition ‘their’ cannot be explained, as to who it is referring to. C-E is incorrect because of the preposition ‘with’. If it is changed to ‘by’, the sentence would be correct. A-F and B-D are correct.
