Spotting Errors Questions in English

(A) The conjunction 'both' is always followed by 'and' as a correlative pair. The phrase 'as well as' is incorrect here. Therefore,the error lies in the first part of the sentence. The correct structure should be: 'Both Maria and her sister are determined to win the dance competition.'

(C) The correlative conjunctions '$Not \ only$' and '$but \ also$' must be used in a pair.
In the given sentence,the structure is incomplete because '$also$' is missing after '$but$'.
Therefore,the correct phrasing should be '$but \ also$ on your ability to plan and execute the strategies'.
Thus,the error lies in part '$C$'.

(C) The phrases 'not only' and 'but also' are used as a pair of correlative conjunctions. Therefore,the word 'and' in option $C$ is incorrect and should be replaced with 'but'. The correct sentence structure is: 'Ram is kind not only in words but also in action.'

(C) The sentence contains a grammatical error in part $C$.
When using 'neither' to indicate a similar negative state for another subject,the structure must be 'neither' + 'helping verb' + 'subject'.
In this sentence,the correct structure should be 'neither has my sister' instead of 'neither my sister'.
Therefore,the error is in part $C$.

(A) When using the correlative conjunction '$not \ only...but \ also$' in a sentence, parallelism must be maintained.
This means that the words following both parts of the conjunction must belong to the same part of speech.
In the given sentence, '$but \ also$' is followed by the gerund '$going$'.
Therefore, '$not \ only$' should be placed before the corresponding gerund '$coming$'.
The corrected sentence structure is: '$Mr. \ Sharma \ stopped \ not \ only \ coming \ to \ hospital \ but \ also \ going \ to \ other \ places \ which \ are \ related \ to \ the \ accident.$'
Thus, the error lies in the placement of '$not \ only$'.

(C) The conjunction $lest$ is used to express a warning or to suggest the negative consequences of an action.
$Lest$ inherently carries a negative meaning,therefore,it should not be followed by a negative word like $not$ or $no$.
In the given sentence,the phrase $lest you should not$ is grammatically incorrect because of the inclusion of $not$.
To correct the sentence,remove $not$ from the third part.
The correct sentence is: $Work hard lest you should lose the game.$

(D) The sentence contains a grammatical error in part $D$.
When expressing a negative agreement with a preceding negative statement,we use 'nor' or 'neither' followed by an auxiliary verb and the subject.
'Never' is an adverb of frequency and is incorrect in this context.
The correct structure is: 'Rahul did not steal the apples from the orchard nor did his brother.'
Therefore,'never' should be replaced with 'nor'.

(B) The word 'hardly' is a negative adverb that implies 'almost not'.
Using 'hadn't' (had not) along with 'hardly' creates a double negative,which is grammatically incorrect in English.
Therefore,the correct phrasing should be 'The medical store hardly had any of the required medicines.'
Thus,the error lies in part $B$.

(C) The correlative conjunction pair used with 'scarcely' is 'when'.
In the given sentence,'while' is incorrectly used.
Therefore,'while' should be replaced by 'when' to make the sentence grammatically correct.
The corrected sentence is: 'Tony had scarcely finished painting when he fell asleep.'

(B) The sentence follows the rule of inversion with the adverb 'Hardly'. When a sentence starts with 'Hardly',it must be followed by the auxiliary verb 'had' and then the subject. The correct structure is: 'Hardly had Ricky reached the platform when the train started.' Therefore,the error is in part $B$ where 'Ricky had' should be 'had Ricky'.

(C) The phrase '$No$ $sooner$' is always followed by the conjunction '$than$'.
In the given sentence,the word '$then$' is incorrectly used.
Therefore,'$then$' should be replaced with '$than$' to make the sentence grammatically correct.
The correct sentence is: '$No$ $sooner$ $did$ $we$ $reach$ $the$ $office$ $than$ $it$ $started$ $raining.$'

(B) The phrases '$as$ $soon$ $as$','$as$ $long$ $as$',and '$so$ $long$ $as$' are not used with '$than$' or '$then$'.
Furthermore,'$as$ $soon$ $as$' is used to indicate simultaneous actions,meaning two actions occurring in immediate succession.
For example: '$As$ $soon$ $as$ she came,the guard opened the door.'
Therefore,the word '$then$' in the second part of the sentence is grammatically incorrect and should be removed.
The correct sentence is: '$As$ $soon$ $as$ the peon rings the bell,all the students assemble in the auditorium.'

(B) The word 'better' is the comparative form of the adjective 'good'.
Using 'more' before 'better' creates a double comparative,which is grammatically incorrect.
Therefore,'more' should be removed from the second part of the sentence to make it 'better than'.

(B) The word 'cousin' is a gender-neutral noun. The phrase 'cousin brother' or 'cousin sister' is considered a redundant expression in English grammar. Since the pronoun 'He' is used,it is already implied that the cousin is male. Therefore,the word 'brother' should be removed. The correct sentence is: 'He is my cousin who works as a doctor.'

(D) The preposition $between$ is generally used for two persons or objects. In this sentence,the number of sons is not specified,implying more than two. Hence,the preposition $among$ should be used instead of $between$.
$Between$ can be used for more than two items only when the items are distinct or clearly identified,for example: $I$ am trying to decide $between$ the blue shirt,the black shirt,and the yellow shirt.
$Among$ is used when items are treated as part of a collective group,for example: $I$ am trying to choose $among$ these shirts. Therefore,the error lies in part $D$.

(B) The error lies in the word 'scissor'. In English,tools consisting of two blades joined together,such as scissors,trousers,or spectacles,are always used in the plural form. Therefore,'scissor' should be replaced with 'a pair of scissors' to make the sentence grammatically correct.

(C) The phrase 'one of the' is always followed by a plural noun because it refers to selecting one item from a group of many. Therefore,'habit' should be replaced with 'habits' to make the sentence grammatically correct.

(B) The subject of the sentence is 'Each',which is a singular pronoun.
Therefore,it requires a singular verb.
The word 'teachers' is part of a prepositional phrase and does not determine the verb form.
Thus,'have' should be replaced with 'has'.
The correct sentence is: 'Each of the teachers has been given an award and a cake.'

(B) The rule for the structure 'More + plural noun + than one' dictates that the verb must be in the plural form.
In this sentence,the subject is 'More students',which is plural.
Therefore,the singular verb 'has' is grammatically incorrect and should be replaced with the plural verb 'have'.
