Model Answer
(a) Error: remain → Correction: <u>must remain</u>
(The sentence requires a modal verb to express obligation/necessity with "vigilant".)
(b) Error: response → Correction: <u>respond</u>
(The verb must be in base form to maintain parallel structure with "remain" — "remain vigilant and respond quickly".)
(c) Error: of → Correction: <u>in</u>
(The correct collocation is "spike in cases", not "spike of cases".)
---
Explanation
- (a) "may remain" suggests mere possibility; the context demands obligation, so must remain is correct.
- (b) "response" is a noun; the sentence needs a verb parallel to "remain" — hence respond.
- (c) "spike" collocates with the preposition in (spike in cases), not "of". Watch preposition-collocation errors carefully — they are common in CBSE editing tasks.
- Always underline the correction in your answer sheet. No marks are given if the correction is not underlined.
