  3. General Aptitude

Select the appropriate option in place of underlined part of the sentence. Increased productivity necessary reflects greater efforts made by the employees. A. Increase in productivity necessary B. Increase productivity is necessary C. Increase in productivity necessarily D. No improvement required

GATE 2015 · General Aptitude · Phrase Meaning · medium

Answer: Option C — 'Increase in productivity necessarily' is the correct replacement.

  1. Diagnose the grammatical error: In 'Increased productivity necessary reflects greater efforts', the word 'necessary' is an adjective modifying nothing correctly; the verb 'reflects' needs an adverb modifier. The correct form is 'necessarily'.
  2. Screen options for the adverb: A uses 'necessary' (adjective) — still wrong. B uses 'is necessary' — restructures the sentence incorrectly. C uses 'necessarily' (adverb) — correct! D claims no improvement needed — wrong, as there is an error. Therefore C is correct.
