Sentence Improvement

S1 General English: Precision, Conciseness & Logic

1 The Foundation (Beyond Spotting Errors)

While "Spotting Errors" asks you to simply locate a grammatical flaw, Sentence Improvement requires you to identify the most elegant and grammatically precise way to fix it. This tests your editorial judgment—a critical skill for drafting government circulars and administrative reports.

  • Precision: The chosen option must fix the grammatical error without altering the original meaning of the sentence.
  • Conciseness: If two options are grammatically correct, UPSC prefers the shorter, more direct one (avoiding wordiness).

Never choose an option just because it "sounds good" colloquially!

2 The Deep Dive: Core Improvement Frameworks

Rule A: Parallelism

Items in a series or list must have the same grammatical structure. Nouns with nouns, gerunds with gerunds, infinitives with infinitives.

Trap: The new principal likes drafting policies, organizing events, and to teach students.

Fix: The new principal likes drafting policies, organizing events, and teaching students.
(Match the -ing forms)

Rule B: Dangling Modifiers

A modifying phrase must sit immediately next to the noun it describes. Otherwise, it logically attaches to the wrong subject.

Trap: Walking into the staff room, the bell rang loudly.

Fix: As I walked into the staff room, the bell rang loudly.
(The bell cannot walk into a room!)

Rule C: Superfluous Expressions

UPSC frequently tests redundancy (pleonasms). Never use two words when one suffices, and never repeat a meaning.

Common Redundancies to CUT:

Return back → Return
Final conclusion → Conclusion
Discuss about → Discuss
Comprise of → Comprise

The audit report is more better than the one submitted last year. A) much better
B) better

Answer: B
Double comparatives (more better) are grammatically illegal. "Better" is already comparative.
