Understanding Active and Passive Voice Transformation

This question asks us to convert a sentence from passive voice to active voice. Understanding the difference between these two voices is crucial in English grammar.

In simple terms:

• Active Voice: The subject performs the action. (e.g., The teacher gives details.)
• Passive Voice: The action is performed on the subject. The subject receives the action. The doer of the action is often mentioned using "by". (e.g., Details are given by the teacher.)

Analyzing the Original Passive Sentence

The given sentence is: "The other details will be given by the concerned teacher."

Let's break it down:

• The subject of the passive sentence is "The other details". These details are receiving the action.
• The verb phrase is "will be given". This is the passive form of the future simple tense.
• The doer of the action, or the agent, is "the concerned teacher", introduced by "by".

Since the action ("will be given") is done to the subject ("The other details") and the doer ("the concerned teacher") is mentioned using "by", this sentence is clearly in the passive voice.

Converting Passive Voice to Active Voice

To convert a passive sentence to active voice, we follow these steps:

1. Identify the doer of the action (the agent). This will become the subject of the active sentence.
2. Identify the passive verb phrase. Convert it to the corresponding active verb form while keeping the tense the same.
3. Identify the subject of the passive sentence. This will become the object of the active sentence.
4. Remove "by" and the passive auxiliary verb (like 'be', 'is', 'are', 'was', 'were', 'been').

Applying these steps to "The other details will be given by the concerned teacher":

1. Doer: "the concerned teacher". This becomes the new subject.
2. Passive verb: "will be given" (future simple passive). The active form is "will give" (future simple active).
3. Passive subject: "The other details". This becomes the new object.

Combining these parts, the active voice sentence is: "The concerned teacher will give the other details."

Evaluating the Options for Active Voice

Now, let's look at the given options and see which one matches our active voice conversion.

• Option 1: "The concerned teacher gave the other details."

  This sentence is in the past tense ("gave"). The original sentence is in the future simple tense ("will be given"). Therefore, this option changes the tense and is incorrect.

• Option 2: "The concerned teacher will give the other details."

  The subject is "The concerned teacher" (the doer). The verb is "will give" (future simple active). The object is "the other details". This sentence correctly follows the structure and tense derived from our active voice conversion. It accurately represents the original meaning in the active voice.

• Option 3: "The concerned teacher will give other details."

  This sentence is in the correct tense and voice, but it omits the article "the" before "other details". While grammatically correct in isolation, transformations should ideally retain the specificity of the original sentence's components unless necessary. The original used "the other details".

• Option 4: "The teacher will give the other concerned details."

  This option changes "the concerned teacher" to "The teacher" and modifies "details" with "concerned". This alters the meaning of the original sentence. The teacher was described as "concerned," not the details.

Comparing the options, Option 2 is the most accurate and direct conversion of the passive sentence "The other details will be given by the concerned teacher" into the active voice while maintaining the original meaning and tense.

Additional Information on Voice Transformation

Voice transformation is a common exercise in English grammar to practice understanding sentence structure and emphasis. While active voice is generally preferred for clarity and directness, passive voice is useful in specific situations, such as when the doer is unknown or unimportant, or when you want to emphasize the action or the receiver of the action.

Key points to remember when converting voice:

• Always maintain the original tense of the verb.
• Ensure the new subject (the original agent in passive) agrees with the verb in the active sentence.
• The original subject of the passive sentence becomes the object of the active sentence.
• Not all sentences can be easily converted to passive voice, especially those without a direct object (intransitive verbs).
