Change of Voice Questions in English

(A) The given sentence is in the $Active$ voice: "After driving Professor Kumar to the museum,she dropped him at his hotel."
To convert this into $Passive$ voice,we focus on the action performed on the object (Professor Kumar).
$1$. The phrase "After driving Professor Kumar to the museum" becomes "After being driven to the museum" in $Passive$ voice.
$2$. The main clause "she dropped him at his hotel" becomes "Professor Kumar was dropped at his hotel" in $Passive$ voice.
Combining these,we get: "After being driven to the museum,Professor Kumar was dropped at his hotel."
Thus,option $A$ is the correct $Passive$ voice conversion.

(B) The given sentence is in the $Active$ voice: "$I$ remember my sister taking me to the museum."
In this structure,the gerund phrase "my sister taking me" acts as the object of the verb "remember".
To convert this to $Passive$ voice,the gerund "taking me" must be changed to the passive gerund form "being taken".
Thus,the object "me" becomes the subject of the passive gerund phrase,resulting in "being taken to the museum by my sister".
The final sentence is: "$I$ remember being taken to the museum by my sister."
Therefore,option $B$ is the correct choice.

(D) The given sentence 'Who is creating this mess?' is in the $Active$ voice (Present Continuous Tense).
To convert an interrogative sentence starting with 'Who' into the $Passive$ voice:
$1$. 'Who' changes to 'By whom'.
$2$. The auxiliary verb 'is' remains,but it is placed before the subject 'this mess'.
$3$. Since it is in the continuous tense,we add 'being' after the subject.
$4$. The main verb 'creating' changes to its past participle form 'created'.
Structure: $By$ $whom$ + $is$ + $subject$ + $being$ + $V_3$?
Applying this,we get: 'By whom is this mess being created?'
Therefore,the correct option is $D$.

(B) The given sentence 'They greet me cheerfully every morning' is in the $Active$ voice.
It is in the $Simple$ $Present$ $Tense$ (Subject + $V_1$ + Object).
The structure for $Passive$ voice in $Simple$ $Present$ $Tense$ is: Object + $am/is/are$ + $V_3$ + by + Subject.
Here,the object is 'me' (which becomes '$I$'),the verb is 'greet' $(V_1)$,and the subject is 'they' (which becomes 'them').
Applying the rule: '$I$' + 'am' + 'greeted' + 'cheerfully' + 'by them' + 'every morning'.
Thus,the correct sentence is: '$I$ am greeted cheerfully by them every morning'.

(C) The given sentence "Darjeeling grows tea" is in the $Active$ voice,where "Darjeeling" is the subject,"grows" is the verb in the simple present tense,and "tea" is the object.
To convert a simple present tense sentence from $Active$ to $Passive$ voice,the structure is: $Object + is/am/are + Past Participle (V3) + by + Subject$.
Here,the object "tea" becomes the subject,the verb "grows" changes to "is grown",and the subject "Darjeeling" follows "by".
Thus,the correct $Passive$ voice sentence is: "Tea is grown in Darjeeling."

(B) The given sentence is in the $Present$ $Perfect$ $Tense$ $(Subject + have/has + V_3 + Object)$.
To convert it into $Passive$ voice,the structure is: $Object + have/has + been + V_3 + by + Subject$.
$1$. The object is "a perfect dam".
$2$. Since "a perfect dam" is singular,we use "has been".
$3$. The verb "built" remains in its $V_3$ form.
$4$. The subject "they" changes to "them" in the agent position.
Thus,the correct sentence is: "$A$ perfect dam has been built by them across the river."

(B) The given sentence "Do you imitate others?" is in the $Simple$ $Present$ $Tense$ in $Active$ voice.
To convert a $Simple$ $Present$ $Tense$ interrogative sentence into $Passive$ voice,the structure is: $Am/Is/Are + \text{object} + \text{past participle} + \text{by} + \text{subject}?$
Here,the subject is "you" and the object is "others".
Since "others" is plural,we use the auxiliary verb "Are".
The past participle of "imitate" is "imitated".
Thus,the $Passive$ voice form is: "Are others imitated by you?"

(C) The given sentence "You need to clean your shoes properly" is in the $Active$ voice.
To convert this into $Passive$ voice, we follow the structure: $Subject + need + to + be + V_3 + \text{adverb}$.
Here, the object "your shoes" becomes the subject.
Therefore, the correct $Passive$ voice form is: "Your shoes need to be cleaned properly."
Thus, option $C$ is the correct answer.

(B) The given sentence "He is said to be very rich" is in the $Passive$ voice.
To convert it into $Active$ voice,we identify the implied subject,which is "People".
The structure "is said to be" indicates a general statement or belief.
Therefore,the $Active$ voice construction is "People say (that) he is very rich."
Thus,option $B$ is the correct answer.

(B) The given sentence,"The invigilator was reading out the instructions," is in the $Past$ $Continuous$ $Tense$ ($Active$ $Voice$).
To convert a $Past$ $Continuous$ $Active$ $Voice$ sentence into $Passive$ $Voice$,the structure is: $Object + was/were + being + V_3 + by + Subject$.
Here,the object is "the instructions" (plural),so we use "were".
The verb "reading out" becomes "being read out".
Thus,the correct $Passive$ $Voice$ sentence is: "The instructions were being read out by the invigilator."

(D) The given sentence is in the $Active$ voice: "You can play with these kittens quite safely."
To convert an $Active$ voice sentence containing a modal verb (like $can$) into $Passive$ voice,the structure is: $Object + can + be + V_3 + (by + Subject)$.
Here,the object is "these kittens".
Applying the rule: "These kittens" + "can be" + "played with" + "quite safely".
Therefore,the correct $Passive$ voice sentence is: "These kittens can be played with quite safely."

(C) The given sentence is in the $Active$ voice: "$A$ child (Subject) + could not have done (Modal verb + perfect infinitive) + this mischief (Object)."
To convert this into $Passive$ voice,the object becomes the subject,and the structure follows: $Object + could + not + have + been + V_3 + by + Subject$.
$1$. The object "This mischief" becomes the new subject.
$2$. The modal verb phrase "could not have done" changes to "could not have been done" in the passive voice.
$3$. The original subject "a child" follows the preposition "by".
Therefore,the correct sentence is: "This mischief could not have been done by a child."

(B) The given sentence "James Watt discovered the energy of steam" is in the $Active$ voice,where the subject is "James Watt",the verb is "discovered" (past tense),and the object is "the energy of steam".
To convert this into $Passive$ voice:
$1$. The object of the $Active$ sentence becomes the subject of the $Passive$ sentence: "The energy of steam".
$2$. Since the verb is in the simple past tense,we use "was/were" + past participle of the verb: "was discovered".
$3$. The subject of the $Active$ sentence becomes the agent in the $Passive$ sentence,introduced by "by": "by James Watt".
Thus,the correct $Passive$ voice sentence is: "The energy of steam was discovered by James Watt."

(B) The given sentence 'She makes cakes every Sunday' is in the $Active$ voice.
To convert it into the $Passive$ voice:
$1$. The object 'cakes' becomes the subject.
$2$. Since the verb 'makes' is in the simple present tense,we use the auxiliary verb 'are' (as 'cakes' is plural).
$3$. The past participle of 'make' is 'made'.
$4$. The subject 'she' becomes the agent 'by her'.
Thus,the correct $Passive$ voice sentence is: 'Cakes are made by her every Sunday'.

(A) The given sentence "She spoke to the official on duty" is in the $Active$ voice,where "She" is the subject and "spoke to" is the verb phrase.
To convert this into $Passive$ voice:
$1$. The object of the active sentence ("the official on duty") becomes the subject of the passive sentence.
$2$. The verb "spoke" (past tense) changes to "was spoken" (past participle form with the auxiliary verb).
$3$. The preposition "to" must be retained as it is part of the phrasal verb structure.
$4$. The subject "She" becomes the agent "by her" at the end.
Thus,the correct $Passive$ voice sentence is: "The official on duty was spoken to by her."

(A) The given sentence "The doctor advised the patient not to eat rice" is in the $Simple$ $Past$ $Tense$ (Active Voice).
To convert it into $Passive$ voice,the object "the patient" becomes the subject.

Therefore,the correct conversion is: "The patient was advised by the doctor not to eat rice."

(A) The given sentence "$I$ cannot accept your offer" is in the $Active$ voice.
To convert it into $Passive$ voice:
$1$. The object "your offer" becomes the subject.
$2$. The modal verb "cannot" remains "cannot be" in the $Passive$ voice.

Thus,the correct $Passive$ voice sentence is "Your offer cannot be accepted by me."

(D) The given sentence is in the $Active$ voice: "You should open the wine about three hours before you use it."
To convert this into the $Passive$ voice,the object "the wine" becomes the subject.
The modal verb "should" remains "should be" in the $Passive$ voice.
The verb "open" becomes the past participle "opened".
Thus,the $Passive$ form is: "The wine should be opened about three hours before it is used."
Option $D$ correctly follows the rules of voice transformation by maintaining the structure of the subordinate clause in the $Passive$ voice.

(A) The given sentence "They will inform the police" is in the $Simple$ $Future$ $Tense$ ($Active$ voice).
To convert it into $Passive$ voice,the structure is: $Object + will/shall + be + V_3 + by + Subject$.

To convert it into $Passive$ voice:
$1$. The object "Peter" becomes the subject.

Thus,the correct $Passive$ voice sentence is: "Peter was surprised at her selection in the crew."

(C) The given sentence "The student committed the mistake" is in the $Active$ voice.
It follows the structure: $Subject$ (The student) + $Verb$ (committed - past tense) + $Object$ (the mistake).
To convert this into $Passive$ voice,the $Object$ becomes the $Subject$,the verb changes to $was/were + past$ $participle$,and the original $Subject$ becomes the agent.
Thus,"The student committed the mistake" becomes "The mistake was committed by the student."
Therefore,option $C$ is the correct answer.

(D) The given sentence "The best coach has trained the team" is in the $Active$ voice.
It follows the structure: $Subject$ (The best coach) + $has/have$ + $past$ $participle$ (trained) + $Object$ (the team).

The correct $Passive$ voice sentence is: "The team has been trained by the best coach."

(B) The given sentence "The Clean India campaign is being run by the government" is in the $Present$ $Continuous$ $Passive$ voice.

(C) The given sentence is in the $Active$ voice: "The students (Subject) must listen (Modal Verb + Verb) to their teachers (Object)."
To convert this into $Passive$ voice,the object becomes the subject,the modal verb remains,and we add "be" + past participle of the verb.
Since the verb "listen" is followed by the preposition "to",it must be retained in the $Passive$ voice.
Thus,the structure is: Object + must + be + past participle (listened) + to + by + Subject.
The correct sentence is: "The teachers must be listened to by the students."

(A) The given sentence "All the exams were passed by Alex" is in the $Passive$ voice,specifically in the $Simple$ $Past$ tense $(was/were + V_3)$.
To convert it into the $Active$ voice,the object $(Alex)$ becomes the subject,and the verb changes to the $Simple$ $Past$ form $(V_2)$.
Therefore,the $Active$ voice form is: "Alex passed all the exams."
Thus,option $A$ is correct.

(B) The given sentence "The Chairman has made a new rule" is in the $Present$ $Perfect$ $Tense$ ($Active$ voice).
To convert a $Present$ $Perfect$ $Active$ sentence into $Passive$ voice,the structure is: $Object + has/have + been + V_3 + by + Subject$.
Here,the object is "$A$ new rule",the subject is "The Chairman",and the verb is "has made".
Applying the rule: "$A$ new rule" + "has been" + "made" + "by" + "the chairman".
Therefore,the correct $Passive$ voice sentence is: "$A$ new rule has been made by the chairman."

(D) The given sentence "My clothes have been ironed" is in the $Present$ $Perfect$ $Passive$ voice.
To convert it into $Active$ voice,we follow the structure: $Subject + has/have + V_3 + Object$.

Therefore,the correct $Active$ voice sentence is: "Someone has ironed my clothes."

(C) The given sentence "Hundreds of students were rescued by the Army" is in the $Passive$ voice,specifically in the $Simple$ $Past$ tense $(was/were + V_3)$.

Thus,the correct $Active$ voice sentence is: "The army rescued hundreds of students."

(D) The given sentence '$The$ $ranking$ $was$ $dropped$ $by$ $the$ $ICC$' is in the $Passive$ voice.
$1$. Identify the tense: The structure '$was$ + past participle' indicates the $Simple$ $Past$ $Tense$ in $Passive$ voice.
$2$. Rule for conversion: To convert $Simple$ $Past$ $Passive$ to $Active$ voice,the structure is: $Subject$ + $V_2$ (past form of verb) + $Object$.
$3$. Apply the rule: The subject of the $Passive$ sentence $(ICC)$ becomes the subject of the $Active$ sentence. The verb '$dropped$' remains in its past form $(V_2)$,and the object $(ranking)$ follows.
Therefore,the correct $Active$ voice sentence is: '$The$ $ICC$ $dropped$ $the$ $ranking$'.
Thus,option $D$ is correct.

(A) The given sentence is in the $Active$ voice: "People believe in God throughout the world."
$1$. The subject is "People",the verb is "believe" (present simple),and the object is "God".
$2$. To convert to $Passive$ voice,the object "God" becomes the subject.
$3$. Since the verb is in the present simple tense,we use the structure: $Object + is/am/are + V_3 + by + Subject$.
$4$. The verb "believe" takes the preposition "in",which must be retained in the $Passive$ voice.
$5$. Thus,the correct $Passive$ form is: "God is believed in throughout the world by the people."
$6$. Option $A$ matches this structure correctly.

(C) The given sentence "Jessica is singing a song" is in the $Present$ $Continuous$ $Tense$ in the $Active$ voice.

Here,the object is "a song",the verb is "is singing",and the subject is "Jessica".
Applying the rule: "$A$ song" + "is" + "being" + "sung" + "by" + "Jessica".
Thus,the correct $Passive$ voice sentence is: "$A$ song is being sung by Jessica."

To convert a $Present$ $Continuous$ $Active$ sentence into $Passive$ voice,the structure is: $Object + is/am/are + being + V_3 + by + Subject$.
Here,the object is 'the match',the verb is 'watching',and the subject is 'they'.
Applying the rule: 'The match' + 'is' + 'being' + 'watched' + 'by' + 'them'.
Therefore,the correct $Passive$ voice sentence is 'The match is being watched by them'.

(A) The given sentence "$I$ have given her a book" is in the $Present$ $Perfect$ $Tense$ $(Subject + have/has + V_3 + Object)$.

Here,the $Object$ is "That necklace",the $Subject$ is "He",and the $V_2$ form is "stole".
Applying the rule: "That necklace" + "was" + "stolen" (past participle of steal) + "by" + "him" (objective case of he).
Therefore,the correct $Passive$ voice is: "That necklace was stolen by him."

(C) The given sentence "The mob killed the thief" is in the $Simple$ $Past$ $Tense$ ($Active$ voice).
To convert a $Simple$ $Past$ $Active$ sentence into $Passive$ voice,the structure is: $Object + was/were + past$ $participle + by + Subject$.
$1$. Identify the object: "the thief".
$2$. Identify the verb: "killed" ($Simple$ $Past$).

(D) The given sentence "The coach is advising the team about the game plan" is in the $Present$ $Continuous$ $Tense$ ($Active$ $Voice$).
To convert a $Present$ $Continuous$ $Active$ sentence into $Passive$ voice,the structure is: $Object + is/am/are + being + V_3 + by + Subject$.
Here,the object is "the team",the verb is "advising",and the subject is "the coach".
Applying the rule: "The team" + "is" + "being" + "advised" + "by the coach" + "about the game plan".
Thus,the correct $Passive$ voice sentence is: "The team is being advised by the coach,about the game plan."

(C) The given sentence is in the $Active$ voice: "The children playing in the street (subject) broke (verb - past tense) my glass window (object)."
To convert it into $Passive$ voice:
$1$. The object "my glass window" becomes the subject.
$2$. Since the verb "broke" is in the simple past tense,we use "was/were + past participle" (was broken).
$3$. The subject "the children playing in the street" becomes the agent,introduced by "by".
Thus,the correct $Passive$ voice sentence is: "My glass window was broken by the children playing in the street."

(C) The given sentence "Who wrote this book?" is in the $Active$ voice,simple past tense.
To convert it into $Passive$ voice:
$1$. The interrogative pronoun "Who" changes to "By whom" at the beginning.
$2$. The auxiliary verb "was" is used because the object "this book" is singular.
$3$. The structure follows: $By \ whom + was + object + V_3 + ?$
$4$. Thus,the correct form is: "By whom was this book written?"

(D) The given sentence "Prepare yourself for the match" is an imperative sentence.
Imperative sentences in the $Active$ voice often follow the structure: $Verb + Object + \text{complement}$.
To convert an imperative sentence into the $Passive$ voice,we use the structure: $Let + Object + be + Past Participle (V_3)$.
However,for instructions or advice,the structure $Be + Past Participle$ is also commonly used.
In this case,"Prepare yourself for the match" simplifies to "Be prepared for the match" as the reflexive pronoun "yourself" is implied in the state of being prepared.
Therefore,option $D$ is the most grammatically correct passive form.

(B) The given sentence is in the $Present$ $Perfect$ $Tense$ in $Active$ voice: "Has the company considered your profile?"
To convert an interrogative sentence of $Present$ $Perfect$ $Tense$ into $Passive$ voice,the structure is: $Has/Have + \text{object} + been + \text{past participle} + \text{by} + \text{subject}?$
Here,the object is "your profile" (singular),so we use "Has".
The $Passive$ voice form is: "Has your profile been considered by the company?"
Therefore,option $B$ is the correct answer.

(C) The given sentence "He plays football" is in the $Simple$ $Present$ $Tense$ (Active Voice).
To convert a $Simple$ $Present$ $Tense$ sentence into $Passive$ voice,the structure is: $Object + is/am/are + V_3 + by + Subject$.
Here,the object is "Football",the verb is "plays" $(V_1)$,and the subject is "He".
Applying the rule: "Football" + "is" + "played" $(V_3)$ + "by" + "him" (objective case of "He").
Therefore,the correct $Passive$ voice sentence is: "Football is played by him."

(A) The given sentence "Contaminated water causes diarrhea" is in the $Active$ voice,where "Contaminated water" is the subject,"causes" is the verb in the simple present tense,and "diarrhea" is the object.
To convert this into the $Passive$ voice:
$1$. The object ("diarrhea") becomes the subject.
$2$. The verb "causes" (simple present) changes to "is caused" (is + past participle).
$3$. The subject ("Contaminated water") becomes the agent introduced by "by".
Therefore,the correct $Passive$ voice sentence is: "Diarrhea is caused by contaminated water."

(B) The given sentence "Improve your driving skills" is an imperative sentence expressing a suggestion or advice.
To convert an imperative sentence expressing advice into $Passive$ voice,we use the structure: $Object + should + be + V_3$ (past participle).
Here,the object is "your driving skills" and the verb is "improve".
Applying the rule: "Your driving skills" + "should be" + "improved".
Thus,the correct $Passive$ voice is "Your driving skills should be improved."

(D) The given sentence is in the $Active$ voice: "The boy (subject) + should not have hit (modal perfect verb) + the puppy (object)."
To convert a sentence with a modal perfect $(should/would/could + have + V_3)$ into the $Passive$ voice,the structure is: $Object + should/would/could + not + have + been + V_3 + by + Subject$.
Applying this rule:
$1$. The object "the puppy" becomes the subject.
$2$. The modal perfect "should not have hit" becomes "should not have been hit".

Thus,the correct $Passive$ voice sentence is: "The puppy should not have been hit by the boy."

(A) The given sentence "Teachers bless him for his kindness" is in the $Simple$ $Present$ $Tense$ ($Active$ voice).
To convert it into $Passive$ voice, the structure is: $Object + is/am/are + V_3 + by + Subject + \text{remaining part}$.

The verb "bless" becomes "is blessed" in the $Passive$ voice.
Thus, the correct sentence is: "He is blessed for his kindness by teachers."

(C) The given sentence "They had not completed their projects" is in the $Past$ $Perfect$ $Tense$ ($Active$ voice).

Here,the object is "Their projects",the auxiliary verb is "had",the negative marker is "not",the passive marker is "been",and the past participle $(V_3)$ of "complete" is "completed".
Thus,the correct $Passive$ voice sentence is: "Their projects had not been completed."

(D) To convert an $Active$ voice sentence into $Passive$ voice for the future simple tense (will + $V_1$):
$1$. The object of the $Active$ sentence ("the entrance exam") becomes the subject of the $Passive$ sentence.
$2$. The auxiliary verb "will" is followed by "be" and the past participle $(V_3)$ of the main verb.
$3$. The verb "clear" becomes "be cleared".
$4$. The subject of the $Active$ sentence ("she") becomes the agent in the $Passive$ sentence ("by her").
Thus,the correct sentence is: "The entrance exam will be cleared by her."
