(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. |
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.
