Sentence Correction Questions in English

(C) The sentence expresses a deduction about a past event. In English grammar,to express a strong deduction about a past action,we use the structure: $Modal\, Verb\, (must) + have + past\, participle$.
$1$. The phrase '$must\, not\, had$' is grammatically incorrect because the modal verb '$must$' should be followed by '$have$' to form the perfect infinitive.
$2$. The correct structure for a past deduction is '$must\, not\, have\, rained$'.
$3$. Therefore,the phrase '$must\, not\, have$' is the correct replacement to complete the sentence: 'The crops are dying; it must not have rained.'

(B) The original phrase '$are\, actively\, to\, safeguard$' is grammatically incorrect because the structure '$are\, to\, safeguard$' implies a future obligation or plan, which does not fit the context of an ongoing action.
The sentence describes an ongoing process of protecting the rights of the poor. Therefore, the present perfect continuous tense or a simple continuous form is appropriate to show that the action started in the past and is continuing.
Option $B$, '$have\, been\, actively\, safeguarding$', correctly uses the present perfect continuous tense to indicate that the courts have been and are still actively protecting these interests.
Thus, the correct sentence is: 'The courts have been actively safeguarding the interests and the rights of the poor.'

(D) The original phrase '$hardly\, possible\, to\, keep$' is grammatically correct in the given context.
$1$. The adverb '$hardly$' is used correctly to mean 'scarcely' or 'almost not'.
$2$. The structure '$hardly\, possible\, to\, keep$' follows the standard English idiom where '$hardly\, possible$' describes the difficulty of maintaining a straight face.
$3$. The other options introduce grammatical errors such as incorrect preposition usage ('for keeping') or illogical phrasing ('hardly impossible').
Therefore, the sentence is already correct as written.

(B) The sentence follows the structure of the correlative conjunction $Hardly...when$.
In this structure,the main clause must be in the past perfect tense because the action happened in the past.
The correct grammatical structure is $Hardly + had + subject + past\, participle + when + past\, simple$.
Therefore,$does\, the\, sun\, rise$ should be replaced by $had\, the\, sun\, risen$.

(D) The given sentence is a conditional sentence of the first type (Type $1$ conditional).
The structure for a Type $1$ conditional is: If + Simple Present,Simple Future.
In the sentence 'You will be late if you $do\, not\, leave$ now',the main clause 'You will be late' is in the future tense,and the 'if' clause 'if you $do\, not\, leave$ now' is in the simple present tense.
Since the grammar follows the correct structure,no correction is required.

(B) The sentence expresses a requirement or necessity to be in a certain state by a specific time in the future.
Since the train departs at $8.30\, pm$,it is necessary to be ready by $7.30\, pm$ to reach the station on time.
'must be' is the most appropriate phrase as it indicates obligation or strong advice.
Therefore,the correct option is $B$.

(D) The sentence is grammatically correct as written. The verb '$level$' in the context of accusations means to direct or aim. When used in the passive voice to describe past actions,the past participle '$levelled$' (or '$leveled$' in American English) is the correct form. The phrase '$levelled$ $against$' is the standard idiomatic expression used when referring to accusations or allegations made towards someone. Therefore,no correction is required.

(C) The original sentence contains a grammatical error in the comparison structure. The correct idiomatic construction for comparing two subjects when one might be equal to or greater than the other is '$as\, adjective\, as\, if\, not\, comparative\, adjective$'.
In this case,the phrase '$as\, tall\, if\, not$' is incomplete. It should be '$as\, tall\, as\, if\, not$'.
Therefore,the corrected sentence is: 'Ramesh is $as\, tall\, as\, if\, not$,taller than Mahesh.'
This structure correctly balances the comparison.

(D) The original sentence is: 'He $hesitated\, to\, listen\, to$ what his brother was saying.'
$1$. The verb '$hesitate$' is followed by the infinitive form of the verb ('$to + \text{verb}$').
$2$. In this case, the verb is '$listen$'.
$3$. The verb '$listen$' is intransitive and requires the preposition '$to$' to connect to its object ('what his brother was saying').
$4$. Therefore, the structure '$hesitated\, to\, listen\, to$' is grammatically correct.
$5$. No correction is required.

(A) The correct phrase to use after the verb $failed$ in this context is the infinitive form. The structure $fail + to + \text{verb}$ is the standard grammatical construction used to indicate an inability to perform an action. Therefore, $in$ should be replaced by $to$. The corrected sentence is: 'The prosecution failed to establish in every case today.'

(A) The original sentence uses the phrase '$do\, not\, have\, to$', which is grammatically incorrect in this context because it implies an obligation or necessity (e.g., '$I$ do not have to go').
The sentence intends to express a lack of a quality or trait (tolerance).
Therefore, the correct phrase is '$do\, not\, have$', which indicates possession of a trait.
Thus, the corrected sentence is: 'One of my drawbacks is that $I$ do not have tolerance of ambiguity.'

(D) The original sentence is: "They $should\, have\, calmly\, thought\, of$ the advantages that would accrue to them."
In English grammar,the structure "should have + past participle" is used to express a past obligation or a past expectation that was not fulfilled.
Here,"thought" is the past participle of the verb "think".
The adverb "calmly" is correctly placed between the auxiliary verb "should have" and the main verb "thought".
Therefore,the original phrase "should have calmly thought of" is grammatically correct.
No correction is required.

(A) The original phrase '$of\, the\, thing\, to\, do$' is grammatically incorrect because the superlative adjective '$easiest$' requires a plural noun phrase when comparing among a group.
Therefore, the correct structure is '$of\, the\, things\, to\, do$'.
This makes the sentence: 'The easiest of the things to do is to ask the address to the postman.'

(D) The sentence describes an action that happened in the past ('demonstrated').
When the main verb is in the past tense,the subordinate clause describing a completed action should also be in the past tense.
'We demonstrated' is in the simple past tense.
The action of preparing the patterns occurred before the demonstration.
Therefore,the past perfect tense '$had\, prepared$' is the most appropriate choice to indicate that the preparation was completed before the demonstration took place.

(A) The original phrase '$are\, wide\, accepted$' is grammatically incorrect because 'wide' is an adjective,but an adverb is required to modify the participle 'accepted'.
$1$. The correct adverb form is 'widely'.
$2$. The sentence structure requires a passive voice construction to indicate that the suggestions are accepted by others.
$3$. Therefore,'$are\, widely\, accepted$' is the correct phrase to complete the sentence.

(B) The original sentence is in the past tense ($felt$,$realised$). The action of being cheated happened before they realised it,which requires the past perfect tense. Since the subject $(they)$ is the receiver of the action,the passive voice $(had\, been\, cheated)$ is required. Therefore,the correct phrase is $had\, been\, cheated$.

(D) The original sentence uses the active voice construction '$should\, heavily\, punished$',which is grammatically incorrect because 'tax evaders' are the recipients of the action (passive voice).
To make the sentence grammatically correct,we need to use the passive voice structure: '$should\, be\, +\, past\, participle$'.
Here,the adverb '$heavily$' modifies the verb '$fined$'.
Therefore,the correct phrase is '$should\, be\, heavily\, fined$'.
Thus,option $D$ is the correct choice.

(D) The original sentence uses the passive voice '$had\, been\, given$ a nice speech',which implies that someone gave a speech to him. However,in the context of the sentence,the person himself delivered the speech. Therefore,the active voice is required.
Since the action of giving the speech happened before the meeting,the past perfect tense '$had\, given$' is the most appropriate choice to indicate that the speech was completed before the session ended and they met him.

(B) The idiom 'to lecture over someone's head' means to speak in a way that is too difficult for the audience to understand. Since the professor is lecturing to multiple pupils,the plural form 'heads' is required. Therefore,the correct phrase is 'over the heads of'.

(A) The verb 'deny' is followed by a gerund (verb + -ing) when referring to an action that happened in the past.
In this sentence,the accused is denying the act of admitting his guilt.
Therefore,the correct form is 'having admitted' (perfect gerund),which indicates that the action of admitting occurred before the action of denying.
Thus,the correct phrase is 'having admitted'.

(A) The original sentence uses the past continuous tense $(was\, beginning)$ for an action that was interrupted by another action. In English grammar,when an action interrupts an ongoing past action,the interrupting action should be in the simple past tense. Since the $film\, began$ while we were standing in the queue,the correct form is $film\, began$.

(D) The given sentence is a third conditional sentence,which describes a hypothetical past situation.
The structure for a third conditional sentence is: $If + \text{past perfect}, \text{would have} + \text{past participle}$.
In the given sentence,the second part is '$I would not have accepted it$',which follows the correct structure.
Therefore,the first part must be in the past perfect tense: '$If I had realised$' or the inverted form '$Had I realised$'.
Among the given options,'$Had I$' is the correct replacement for '$If I would have$' because '$Had I realised$' is grammatically equivalent to '$If I had realised$'.

(B) The correct phrase is $crime \,has \,grown \,rapidly$.
In the original sentence,the noun $growth$ is used incorrectly as a verb.
Since the sentence describes an action that started in the past and continues to the present (indicated by the word $since$),the present perfect tense $(has \,grown)$ is required.
$Rapidly$ is the correct adverb to modify the verb $grown$.

(D) The original sentence is 'They failed $in\, their\, attempt\, to\, repair$ the demolished portion of that building.'
In English grammar, the verb 'fail' is followed by the preposition 'in' when referring to an attempt or endeavor, and the structure 'fail in one\'s attempt to do something' is idiomatic and grammatically correct.
Therefore, the phrase 'in their attempt to repair' is already correct.
Hence, no correction is required.

(D) The original sentence is '$I$ $earnestly$ $believe$ $that$ you will visit our relatives during your forthcoming trip to Mumbai.'
$1$. The phrase '$I$ $earnestly$ $believe$ $that$' is grammatically correct.
$2$. The adverb '$earnestly$' modifies the verb '$believe$',which is appropriate in this context to express a sincere or serious belief.
$3$. The sentence structure follows the standard subject-verb-object pattern,and the tense usage is consistent.
$4$. Therefore,no correction is required.

(B) The phrase '$By \,such\, time$' is grammatically incorrect in this context. The correct idiomatic expression to indicate a point in the future by which an action will be completed is '$By \,the \,time$'. Therefore,the sentence should read: '$By \,the \,time$ you finish that chapter,$I$ will write a letter.'

(A) The original phrase $have\, kept\, in\, mind\, to\, try\, and\, maintain$ is grammatically incorrect because 'try and' is an informal idiom. In formal English,'try to' is preferred. Furthermore,the structure 'to try and maintain' is redundant. The correct idiomatic expression is 'try to maintain'. Therefore,the phrase should be corrected to 'have kept in mind to try to maintain'. However,looking at the options provided,the most appropriate correction for the intended meaning is to use the infinitive form correctly. Since the original sentence structure is flawed,option $A$ provides a more direct and grammatically sound alternative.

(C) The original sentence uses the structure '$in\, such\, mess\, there$'.
To make the sentence grammatically correct, we need to use the correlative conjunction structure '$such...that$'.
$1$. The article '$a$' is required before the noun phrase '$mess$'.
$2$. The conjunction '$that$' is required to connect the cause (the mess) with the result (no leader to set things right).
$3$. Therefore, the phrase '$in\, such\, a\, mess\, that\, there$' is the correct replacement.
Thus, the correct option is $C$.

(C) The original sentence uses the preposition $in$ after the word $difference$. When comparing two items, the correct preposition to use is $between$. Therefore, the phrase $any \,difference \,in$ should be replaced with $any \,difference \,between$. The correct option is $C$.

(B) The phrase "gone away from" is grammatically incorrect in this context. The correct idiomatic expression to describe the disappearance or extinguishing of light is "gone out of". Therefore,the sentence should read: "Friends and comrades,the light has gone out of our lives and there is darkness everywhere."

(C) The original sentence contains a logical error. The phrase '$not\, to\, refrain\, from$' implies that the doctor is advising the patient to continue smoking, which contradicts the context of 'ill health'.
The correct advice for someone in ill health is to stop smoking. Therefore, the phrase '$not\, to\, refrain\, from$' should be replaced with '$to\, refrain\, from$'.
Thus, the corrected sentence is: 'Because of his ill health, the doctor has advised him to refrain from smoking.'

(B) The original phrase '$the\, best\, of\, the\, performers$' is grammatically incorrect because the superlative degree '$best$' requires the definite article '$the$' followed by a noun or a prepositional phrase that correctly identifies the group.
In this context,the phrase '$the\, best\, of\, the\, performers$' is actually grammatically acceptable in standard English as it refers to the top individuals from the group of performers.
However,if we look at the options provided,'$the\, best\, among\, the\, performers$' is a more precise and idiomatic way to express the selection from a group.
Therefore,the most appropriate replacement is '$the\, best\, among\, the\, performers$'.

(D) The original sentence is in the past tense because the main verb phrase is '$was\, not\, known$'.
Therefore, the subordinate clause must also be in the past tense to maintain tense consistency.
'$What\, happens\, to$' is in the present tense.
Replacing it with '$What\, happened\, to$' correctly aligns the tense of the clause with the past tense of the main verb.
Thus, the correct phrase is '$What\, happened\, to$'.

(D) The sentence uses a parallel structure. The gerund phrase '$Making\, friends$' is used as the subject. To maintain grammatical parallelism, the phrase following the comparative '$more\, rewarding\, than$' must also be in the gerund form. Therefore, '$to\, make\, enemies$' should be replaced by '$making\, enemies$'. This ensures that both sides of the comparison are consistent.

(B) The original sentence uses the phrase '$were \,delight$',which is grammatically incorrect because 'delight' is a noun or a verb,but here a past participle is required to describe the state of the subjects.
The sentence is in the past tense ('saw'). Therefore,the correct passive construction to describe their state is '$were \,delighted$'.
Thus,option $B$ is the correct choice.

(C) The sentence structure for expressing a past obligation or a past regret is 'modal verb + have + past participle'.
In this case,the modal verb is 'should'.
Therefore,the correct structure is 'should not have' followed by the past participle 'done'.
Thus,the phrase '$should \,not\, had$' should be replaced by '$should \,not\, have$'.

(B) The sentence follows the structure: $No \, sooner + \text{auxiliary verb} + \text{subject} + \text{verb} + \text{than} + \text{clause}$.
Since the second part of the sentence ('the curtain rose') is in the past tense,the first part must also be in the past tense.
'No sooner' is followed by the auxiliary verb 'did' or 'had'.
If we use 'did',the verb must be in the base form (did the bells ring).
If we use 'had',the verb must be in the past participle form (had the bells rung).
Comparing the options,'did the bells ring' $(B)$ is grammatically correct and maintains the plural subject 'bells' used in the original sentence.

(B) The original phrase '$order\, immediately\, dismissed\, him.$' is grammatically incorrect because it uses a verb where a noun is required as the object of the action. The manager ordered the 'dismissal' (noun) of the assistant. The adjective 'immediate' is required to modify the noun 'dismissal'. Therefore,the correct construction is 'ordered his immediate dismissal'.

(B) The verb $attend$ is used as a transitive verb when it means to be present at an event. Therefore, it does not require the preposition $to$ when used in this context. The phrase $attended\, to$ means to deal with or take care of something. Since the sentence refers to people being present at a meeting, the correct usage is simply $attended$. Thus, the phrase $attended\, to\, by\, all$ should be replaced by $attended\, by\, all$.

(D) The original sentence uses the past tense '$was$' in the second clause, while the first clause '$If he has to spend$' is in the present tense. To maintain grammatical consistency (conditional sentence type $1$), the second clause should also be in the present tense. Therefore, '$was$' should be replaced by '$is$'. The phrase '$really a wastage$' is grammatically correct as it uses the adverb '$really$' to modify the noun phrase '$a wastage$'. Thus, the correct replacement is '$is really a wastage$'.

(B) The word $small$ is grammatically incorrect in this context because it is used to describe the size of an object,not the quantity of an uncountable noun like $attempt$ (in the sense of effort).
$Attempt$ is an uncountable noun here,representing the concept of effort. For uncountable nouns,we use quantifiers like $little$ or $much$.
$Little$ means 'hardly any' or 'almost none',which fits the context of the sentence implying that there has been almost no real attempt at planning.
Therefore,the correct phrase is $little$.

(B) The correct idiomatic expression is '$stood\, on\, ends$'.
This phrase is used to describe the reaction of hair when someone is frightened or shocked.
Since the sentence is in the past tense ('saw'),the verb must also be in the past tense ('stood').
Therefore,'$stood\, on\, ends$' is the grammatically correct replacement.

(A) The phrase "$The\, long\, and\, short\, of\, it$" is a standard English idiom that means the essential summary or the main point of a matter.
Since the original sentence uses the incorrect phrase "$The\, long\, or\, short\, of\, it$",it must be replaced by the correct idiomatic expression "$The\, long\, and\, short\, of\, it$".
Therefore,option $A$ is the correct choice.

(C) In an indirect question or a subordinate clause,the word order must be subject-verb,not verb-subject.
The phrase '$why\, did\, you\, not\, speak$' is an interrogative clause acting as the object of the verb 'tell'.
In such clauses,the auxiliary verb 'did' should not precede the subject 'you'.
Therefore,the correct structure is 'why you did not speak'.
Thus,option $C$ is the correct replacement.

(D) The phrase $curry\, favour$ is a standard English idiom that means to try to gain someone's favor by flattery or obsequious behavior. The sentence is grammatically correct as it is written. Therefore,no correction is required.

(D) The word $sugar$ is an uncountable noun.
In negative sentences,we use the determiner $any$ instead of $a$ or $some$ with uncountable nouns.
Therefore,the correct phrase to replace $a$ is $any$.
The corrected sentence is: "$I$ have got some tea,but $I$ do not have any sugar."

(D) The sentence uses the third conditional structure,which is used to talk about hypothetical situations in the past. The structure for the 'if' clause in the past perfect is '$Had + subject + past\, participle$'.
In the given sentence,'$Had\, I\, realised$' follows this structure correctly $(Had + I + realised)$.
Therefore,the sentence is already grammatically correct,and no correction is required.

(C) The original sentence contains a grammatical error in the comparative structure. When using the construction '$as\, adjective\, as$',the second '$as$' must be followed by the comparison. However,when combining this with a comparative adjective ('healthier'),the correct structure is '$as\, adjective_1, \text{if not } adjective_2-er$'.
In the given sentence,the phrase '$as\, healthy\, as,\, if\, not\, healthier$' is redundant because the second '$as$' clashes with the comparative 'than'. The correct idiomatic expression is '$as\, healthy, \text{if not healthier}$' than British workers. This structure correctly balances the positive degree comparison with the comparative degree.

(B) The sentence describes a past state ('was very tired') caused by an action that started in the past and continued up to that point in the past.
For an action continuing up to a point in the past,we use the Past Perfect Continuous tense.
Therefore,'$he\, is\, working$' should be replaced by '$he\, had\, been\, working$'.

(C) The word $Jeans$ is a plural noun in English because it refers to a garment consisting of two legs. Therefore,it requires a plural verb. The correct sentence is: $Jeans$ $were$ not allowed in Maria's college.
