Each question consists of four sentences on a topic. Some sentences are grammatically incorrect or inappropriate. Select the option that indicates the grammatically correct and appropriate sentence(s).
A. After decades of research and plethora of seeming infinite numbers of dead-end leads, scientists have finally discovered the cause of the biggest public health scourge of our time –Obesity.
B. It is not lack of exercise, it is not what we are eating, and neither is it certainly what is passed on through our genes.
C. The obesity epidemic is caused by fat people passing on their fatness to other people and making them fat.
D. Though this confusion between cause and correlation are enough to invalidate any of the conclusions drawn from this study, it is certainly not the only problem.
Sentence A has two errors.
‘Plethora’ refers to a large amount of something and has to be preceded by the article ‘a’. ‘Infinite’ is an adjective here that qualifies the noun ‘number’ and should therefore be qualified by the adverb form of the word ‘seeming’ (seemingly). In sentence B there is an error with respect to the parallel construction of the sentence. The parallel structure would be maintained if the clauses were of similar form – ‘it is not lack. . ., it is not what we. . ., and it is certainly not what. . .’ . Sentence D suffers from subject-verb mismatch. The subject of the plural verb ‘are’ is the singular word ‘confusion’; hence we need the singular form ‘is’. Only sentence C is correct. Hence, [e].
