A statement has been given with three words in
bold. There are three answer choices given below, one or more of which may act as replacement to the original set of words. You are required to find the correct combination of the answer choices. In case the original set is correct, select ‘No improvement’.

I. instrument, disturbance, compounds II. probe, variation, substances III. body, derive, moleculesSolution
Solution In the given sentence, the word ‘platelets’ is used incorrectly as it refers to a type of cell in human bodies. The correct words here will be ‘disturbance’ and ‘variation’ that denote some unusual occurrence in planet’s outer layers. The word ‘elementary’ is again incorrect as the sentence requires a noun. The words ‘compounds’ and ‘substances’ are correct words here. Hence, the correct answer is option B.
