Sentence Improvement

Sentence Improvement

Concept

Sentence Improvement presents a full sentence with a specific part underlined or highlighted. Four alternative ways to express that part are given as options (A, B, C, D), with Option A typically being the original phrasing. You must select the option that most effectively improves the sentence — in terms of grammar, clarity, idiom, or conciseness. If no improvement is needed, the answer is Option A (the original).

The key distinction from Spotting Errors is that here you are choosing the best way to express something — not just finding what’s wrong. The original sentence might be grammatically correct but stylistically awkward, redundant, or idiomatically wrong. SSC also frequently tests fixed prepositional phrases and idiomatic expressions in this section.

The improvement typically falls into one of these categories:

• Grammatical correction: Wrong verb form, subject-verb disagreement, wrong tense
• Prepositional improvement: Wrong preposition in an idiom
• Conciseness: Removing redundant words without changing meaning
• Clarity: Reordering words for better readability
• Register: Replacing informal/colloquial with standard English

Key Points

• Always compare all four options against the original before deciding. Do not assume the original is wrong.
• Idiom-based prepositions are highly tested: “independent of” (not “from”), “afraid of,” “capable of,” “die to” (not “die from”), “robbed of,” “deprived of,” “consists of” (not “consists from”).
• Tense consistency across clauses is critical — watch for “had been” vs “was,” “has been” vs “had been” distinctions.
• Conciseness matters: “In order to” can always be replaced with “to.” “Due to the fact that” can be replaced with “because.”
• Voice consistency: If the sentence starts in active voice, the improvement should maintain it unless passive is clearly better.
• Word order for adverbs: “He always comes late” is preferred over “He comes always late.” Placement of “only,” “just,” “ever,” “never” — these typically go before the main verb.

Worked Example

Q: He is having a bath. (a) He is having a bath. (Original) (b) He is having a shower. (c) He is taking a bath. (d) He takes a bath.

Approach: “Having a bath” is not idiomatic in standard English. The idiomatic expression is “taking a bath.” Option (c) is the most natural and correct. (b) is also idiomatic but changes “bath” to “shower” — this changes meaning. (d) is grammatically correct but changes the tense (present continuous → simple present).

Answer: C

SSC Pattern / Tips

• Preposition errors account for 25-30% of all Sentence Improvement questions — memorize fixed pairs
• Verb form errors (especially participle vs infinitive, “seeing” vs “to see”) appear in 20-25% of questions
• Conciseness is tested frequently — learn to spot redundant phrases quickly
• “In order to” → “to” is a very common improvement
• “Because of the reason that” → “because” or “since” is another common pattern
• Do NOT change meaning when improving — if the meaning shifts, the option is wrong even if it is grammatically cleaner
