Understanding Active and Passive Voice

In English grammar, sentences can be expressed in either active voice or passive voice. The voice of a verb shows whether the subject performs the action (active voice) or is acted upon (passive voice).

• Active Voice: The subject performs the action. Structure: Subject + Verb + Object.
• Passive Voice: The subject receives the action. Structure: Object + form of 'to be' + Past Participle + by + Subject (optional).

Analyzing the Given Sentence

The sentence provided is: "The lawyer had presented the facts of the case well."

Let's break down this sentence:

• Subject: The lawyer (the one performing the action)
• Verb Phrase: had presented (the action being performed)
• Object: the facts of the case (the receiver of the action)
• Adverb: well (describes how the action was performed)

The verb phrase "had presented" indicates the tense is Past Perfect.

Converting Past Perfect Active to Passive Voice

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

1. Identify the object of the active sentence. This will become the subject of the passive sentence.
2. Use the helping verbs "had been".
3. Use the past participle of the main verb from the active sentence.
4. If necessary, include "by" followed by the original subject of the active sentence (the doer of the action).
5. Include any adverbs or other parts of the sentence, usually placed after the past participle or at the end.

The structure for Past Perfect passive voice is: Object + had been + Past Participle + (by Subject) + (Adverb/Other).

Applying Conversion Steps to the Sentence

Let's apply the steps to "The lawyer had presented the facts of the case well."

1. Object becomes Subject: The object is "the facts of the case". This becomes the new subject.
2. Use "had been": The sentence will start with "The facts of the case had been...".
3. Past Participle: The main verb is "presented". The past participle is also "presented". So we have "The facts of the case had been presented...".
4. Include "by Subject": The original subject is "the lawyer". We add "by the lawyer". So we have "The facts of the case had been presented by the lawyer...".
5. Include Adverb: The adverb is "well". It can be placed after "presented". So the sentence becomes "The facts of the case had been presented well by the lawyer."

Therefore, the passive voice transformation is "The facts of the case had been presented well by the lawyer."

Evaluating the Options

Let's examine each option provided:

• Option 1: The facts of the case had presented the lawyer well.

  This option makes "the facts of the case" the subject, but the verb "had presented" is still in active voice. The meaning is also significantly changed; it suggests the facts themselves presented the lawyer, which is not the intended meaning.

• Option 2: The facts of the case had been presented well by the lawyer.

  This option correctly makes "the facts of the case" the subject, uses the correct Past Perfect passive structure "had been presented", includes the adverb "well", and correctly identifies the doer of the action with "by the lawyer". This matches our derived passive sentence.

• Option 3: The facts of the case were being presented by the lawyer well.

  This option uses the passive structure for Past Continuous tense ("were being presented"), not Past Perfect tense ("had been presented"). Therefore, it does not correctly reflect the tense of the original sentence.

• Option 4: The lawyer was presented well by the facts of the case.

  This option keeps "The lawyer" as the subject and uses the passive structure for Simple Past ("was presented"). It completely changes the subject and tense and does not correctly transform the original sentence.

Based on the analysis, only Option 2 correctly expresses the given sentence in passive voice while maintaining the original meaning and tense.

Additional Information: Why Use Passive Voice?

While active voice is generally preferred for clarity and directness, passive voice is useful in specific situations:

• When the doer of the action is unknown or unimportant.
• When you want to emphasize the action or the recipient of the action rather than the doer.
• In scientific or technical writing, where the process or result is more important than who performed the action.
• To vary sentence structure.
