Sentence Improvement tests grammatical precision, syntax rules, conciseness, and idiomatic accuracy. Instead of merely spotting an error, you must identify the most elegant, grammatically perfect correction, or select 'No improvement' if the original phrasing is flawless.

1. Core Focus Areas for Improvement

In SSC CGL, improvement questions primarily target these three pillars of sentence composition:

1. Redundancy

Removing repetitive or unnecessary words that clog the sentence meaning.

"Return back" -> "Return" | "Reason because" -> "Reason that"

2. Subject-Verb Agreement

Verbs must match the true grammatical subject, not the closest noun phrase.

"The quality of these mangoes is (not are) good."

3. Parallelism

Maintaining the same grammatical form for elements listed in series or comparisons.

"He likes swimming, running, and to paint (incorrect) -> painting."

2. Sentence Improvement Filtration Strategy

Use this step-by-step checklist whenever you encounter an improvement question:

Check Tense Consistency

If the main clause is in the past tense, the subordinate clause must also be in the past tense, unless it states a universal truth or scientific fact.

Look for Conditional Clauses Rules

For future conditions, use Simple Present in the 'if' clause and Simple Future in the main clause. For hypothetical/past conditions, use 'had + V3' paired with 'would have + V3'. Never mix these structures up!

Observe Position of Modifiers

Adverbs (like 'only', 'almost') and modifying phrases must be placed as close as possible to the words they modify. Placing them incorrectly changes the meaning completely.

Don't Overlook "No Improvement"

Around 15-20% of exam questions require no correction. If a sentence has a clear subject, correct verb tense, appropriate preposition, and sound logical meaning, confidently choose 'No improvement'.

3. 20 Solved Practice Questions

Question 01Exam Pattern

Improve the bracketed part of the sentence: "He [had returned back] from Delhi last night."

A) returned back

B) returned

C) had returned

D) No improvement

Correct answer: B) returned

Solution

Step 1: Notice the specific time indicator 'last night' (demands Simple Past tense).

Step 2: Note the redundant use of 'back' with the verb 'returned' (return itself means to come back).

Step 3: Option B correctly uses simple past 'returned' and removes the redundancy.

Conclusion: Option B.

Question 02Exam Pattern

Improve the bracketed part of the sentence: "If I [had seen] him, I would have told him the news."

A) saw

B) would see

C) had saw

D) No improvement

Correct answer: D) No improvement

Solution

Step 1: Identify the conditional structure: 'would have told' (type 3 conditional).

Step 2: Type 3 conditional structure requires: If + Past Perfect (had + V3) in the conditional clause.

Step 3: 'had seen' is past perfect and mathematically correct here.

Conclusion: Option D.

Question 03Exam Pattern

Improve the bracketed part of the sentence: "The standard of living in our city [is different than] other cities."

A) is different from that of

B) is different from

C) differs than

D) No improvement

Correct answer: A) is different from that of

Solution

Step 1: Check the comparison. We are comparing 'the standard of living' of one city to another, not the city itself.

Step 2: Use 'different from' instead of 'different than'.

Step 3: 'that of' represents 'the standard of living' to prevent repetition. Option A provides the grammatically correct comparative structure.

Conclusion: Option A.

Question 04Exam Pattern

Improve the bracketed part of the sentence: "The teacher asked the student [why was he late]."

A) why he was late

B) that why he was late

C) why is he late

D) No improvement

Correct answer: A) why he was late

Solution

Step 1: The sentence is in indirect speech (declarative structure, not a direct question).

Step 2: In indirect questions, the subject must come before the verb (assertive word order).

Step 3: Avoid using 'that' before interrogative adverbs like 'why'. Option A is correct.

Conclusion: Option A.

Question 05Exam Pattern

Improve the bracketed part of the sentence: "She [scarcely never] goes to the theater because she dislikes crowded spaces."

A) scarcely ever

B) rarely never

C) ever scarcely

D) No improvement

Correct answer: A) scarcely ever

Solution

Step 1: 'Scarcely' is a negative adverb.

Step 2: Using 'scarcely' with 'never' creates a double negative error.

Step 3: Correct it by using 'scarcely ever' (meaning almost never).

Conclusion: Option A.

Question 06Exam Pattern

Improve the bracketed part of the sentence: "The news [are] too good to be true."

A) is

B) were

C) have been

D) No improvement

Correct answer: A) is

Solution

Step 1: The noun 'news' appears plural but is always treated as singular in grammatical numbers.

Step 2: Thus, it must take a singular verb 'is'.

Conclusion: Option A.

Question 07Exam Pattern

Improve the bracketed part of the sentence: "Not only the students [but also the principal were] present at the meeting."

A) but also the principal was

B) but the principal were also

C) and also the principal was

D) No improvement

Correct answer: A) but also the principal was

Solution

Step 1: When two subjects are joined by 'not only... but also', the verb agrees with the subject closest to it.

Step 2: The closest subject is 'the principal' (singular).

Step 3: The verb must be singular 'was'. Option A is the correct pairing.

Conclusion: Option A.

Question 08Exam Pattern

Improve the bracketed part of the sentence: "The passenger was [prevented to enter] the station without a valid ticket."

A) prevented from entering

B) prevented entering

C) prevented to entering

D) No improvement

Correct answer: A) prevented from entering

Solution

Step 1: Identify the prepositional pattern of the verb 'prevent'.

Step 2: 'Prevent' strictly takes the preposition 'from' followed by the gerund form (V1 + ing).

Step 3: Therefore, 'prevented from entering' is the correct construction.

Conclusion: Option A.

Question 09Exam Pattern

Improve the bracketed part of the sentence: "No sooner [he had arrived] than the meeting commenced."

A) had he arrived

B) did he arrived

C) he arrived

D) No improvement

Correct answer: A) had he arrived

Solution

Step 1: The sentence begins with 'No sooner'.

Step 2: Apply the law of inversion, placing the auxiliary verb ('had' or 'did') before the subject ('he').

Step 3: Option A ('had he arrived') is correct. Option B is incorrect because 'did' must be followed by a base verb ('arrive').

Conclusion: Option A.

Question 10Exam Pattern

Improve the bracketed part of the sentence: "He is working in this factory [since five years]."

A) has been working in this factory for five years

B) is working in this factory for five years

C) was working in this factory since five years

D) No improvement

Correct answer: A) has been working in this factory for five years

Solution

Step 1: For an action that started in the past and continues in the present, use Present Perfect Continuous ('has been working').

Step 2: 'five years' is a duration/period of time, so it must take 'for' instead of 'since'.

Conclusion: Option A.

Question 11Exam Pattern

Improve the bracketed part of the sentence: "Neither of the two books [are] helpful for the exam preparation."

A) is

B) were

C) have been

D) No improvement

Correct answer: A) is

Solution

Step 1: The subject 'Neither' (meaning none of the two) is always treated as singular.

Step 2: Do not get confused by the plural noun 'books' in the prepositional phrase 'of the two books'.

Step 3: The verb must be singular 'is'.

Conclusion: Option A.

Question 12Exam Pattern

Improve the bracketed part of the sentence: "He resides [in a three-bedrooms flat] in the heart of Mumbai."

A) in a three-bedroom flat

B) in three-bedroom flats

C) within three-bedrooms flat

D) No improvement

Correct answer: A) in a three-bedroom flat

Solution

Step 1: In a compound noun functioning as an adjective ('three-bedroom' modifying 'flat'), the modifying noun must never be pluralized.

Step 2: Thus, 'three-bedrooms flat' is incorrect; it must be 'three-bedroom flat'.

Conclusion: Option A.

Question 13Exam Pattern

Improve the bracketed part of the sentence: "If he [will work] hard, he will pass the test."

A) works

B) worked

C) will have worked

D) No improvement

Correct answer: A) works

Solution

Step 1: In a first conditional sentence, the clause starting with 'If' must be in the Simple Present tense.

Step 2: The main clause uses simple future ('will pass').

Step 3: Replace 'will work' with 'works'.

Conclusion: Option A.

Question 14Exam Pattern

Improve the bracketed part of the sentence: "The reason why he failed was [because he did not study]."

A) that he did not study

B) due to his not studying

C) since he didn't study

D) No improvement

Correct answer: A) that he did not study

Solution

Step 1: The phrase 'The reason why' is redundant when paired with 'because', 'due to', or 'since'.

Step 2: The correct correlative complement for 'The reason why' is 'that'.

Conclusion: Option A.

Question 15Exam Pattern

Improve the bracketed part of the sentence: "The climate of Shimla is [colder than Delhi]."

A) colder than that of Delhi

B) colder from Delhi

C) more colder than Delhi

D) No improvement

Correct answer: A) colder than that of Delhi

Solution

Step 1: The sentence compares 'the climate' of Shimla to the city 'Delhi' (illogical comparison).

Step 2: We must compare Shimla's climate to Delhi's climate.

Step 3: Use 'that of Delhi' to represent 'the climate of Delhi'. Option C uses double comparatives ('more colder'), which is incorrect.

Conclusion: Option A.

Question 16Exam Pattern

Improve the bracketed part of the sentence: "He has [been working since] morning and is tired now."

A) worked since

B) works since

C) is working since

D) No improvement

Correct answer: D) No improvement

Solution

Step 1: The sentence describes an ongoing action starting from a specific point in time ('morning').

Step 2: 'since' is correctly used for a point of time.

Step 3: Present perfect continuous ('has been working') is perfectly correct.

Conclusion: Option D.

Question 17Exam Pattern

Improve the bracketed part of the sentence: "Let you and [I] do this piece of work together."

A) me

B) myself

C) mine

D) No improvement

Correct answer: A) me

Solution

Step 1: The word 'Let' is a transitive verb and must always be followed by pronouns in the objective case.

Step 2: The objective case of 'I' is 'me'.

Step 3: Hence, 'you and me' is the correct pronoun configuration.

Conclusion: Option A.

Question 18Exam Pattern

Improve the bracketed part of the sentence: "The criminal [was hung] in public for his heinous crimes yesterday."

A) was hanged

B) hunged

C) had hunged

D) No improvement

Correct answer: A) was hanged

Solution

Step 1: The verb 'hang' has two past participle forms based on meaning.

Step 2: 'Hang -> hung -> hung' means to suspend an object. 'Hang -> hanged -> hanged' specifically means execution by hanging.

Step 3: Since the criminal was executed, 'was hanged' is the correct passive voice.

Conclusion: Option A.

Question 19Exam Pattern

Improve the bracketed part of the sentence: "She prefers tea [than] coffee in the morning."

A) to

B) over

C) against

D) No improvement

Correct answer: A) to

Solution

Step 1: The verb 'prefer' (and adjectives like 'preferable') is always paired with the preposition 'to', not 'than' or 'over'.

Conclusion: Option A.

Question 20Exam Pattern

Improve the bracketed part of the sentence: "He walked fast [lest he should not miss] the early bus."

A) lest he should miss

B) lest he might miss

C) lest he would miss

D) No improvement

Correct answer: A) lest he should miss

Solution

Step 1: 'Lest' means 'for fear that' and inherently contains a negative meaning.

Step 2: Do not use 'not' with 'lest'.

Step 3: 'Lest' must be followed by 'should'. Option A is correct.

Conclusion: Option A.

Strategy errors to avoid

Illogical Comparisons

Always compare apples to apples. Writing "The streets of Kolkata are wider than Mumbai" is wrong. It must be "wider than those of Mumbai". Look out for comparisons missing 'that of' or 'those of'.

Double Comparatives and Superlatives

Never pair 'more' or 'most' with adjectives already having '-er' or '-est' endings (e.g., "more faster" or "most smartest" are completely incorrect).
