Understanding Active and Passive Voice Conversion

The question asks us to convert an active voice sentence into its correct passive voice form. The original sentence is "Did you inform him about the ticket cancellation?". This sentence is in the Simple Past Tense and is an interrogative (question) sentence.

Key Concepts: Active vs. Passive Voice

• Active Voice: The subject of the sentence performs the action. (Example: You informed him.)
• Passive Voice: The subject of the sentence receives the action. The focus is often on the action itself or the receiver of the action. (Example: He was informed by you.)

Rules for Converting Simple Past Tense Interrogative (Did...?) to Passive Voice

To convert an active sentence like "Did + Subject + Verb (base form) + Object + ?" into passive voice, we follow these general steps:

1. Identify the subject, verb, and object in the active sentence. (Subject: you, Verb: inform, Object: him).
2. The object of the active sentence becomes the subject of the passive sentence. ("him" becomes "he").
3. The verb in the active sentence (base form after 'Did') is converted to the past participle form. ("inform" becomes "informed").
4. Use the appropriate form of the verb 'to be' in the past tense (Was/Were) before the past participle. Since the new subject is "he" (singular), we use "Was".
5. The subject of the active sentence becomes the object of a preposition, usually 'by'. ("you" becomes "by you").
6. The question structure needs to be maintained. Start the passive sentence with "Was" or "Were".
7. Combine these parts to form the passive sentence: Was/Were + new subject + past participle + remaining part of the sentence + by + original subject + ?.

Applying the Rules to the Given Sentence

Let's convert "Did you inform him about the ticket cancellation?" step-by-step:

• Original sentence: Did you inform him about the ticket cancellation?
• Subject (Active): you
• Verb (Active): inform
• Object (Active): him
• New Subject (Passive): him → he
• Past Participle of the verb: inform → informed
• Appropriate 'to be' verb in past tense for 'he': Was
• Original Subject as object of 'by': by you
• Remaining part: about the ticket cancellation

Putting it together in the interrogative structure:

Was + he + informed + about the ticket cancellation + by you + ?

This gives the passive sentence: "Was he informed about the ticket cancellation by you?"

Analyzing the Options

Let's evaluate each option against our derived passive form:

• Option 1: Was he informed about the ticket cancellation by you?
  This matches the structure and tense we derived. It uses "Was" for the singular subject "he", the past participle "informed", and includes "by you". This is the correct passive form for a Simple Past interrogative sentence.
• Option 2: Will he be informed about the ticket cancellation by you?
  This uses "Will be informed", which is the passive form for the Simple Future Tense. The original sentence is in Simple Past Tense, so this option is incorrect.
• Option 3: Is he being informed about the ticket cancellation by you?
  This uses "Is being informed", which is the passive form for the Present Continuous Tense. The original sentence is in Simple Past Tense, so this option is incorrect.
• Option 4: Was he being informed about the ticket cancellation by you?
  This uses "Was being informed", which is the passive form for the Past Continuous Tense. The original sentence is in Simple Past Tense, so this option is incorrect.

Based on the analysis, Option 1 is the only correct passive conversion of the given Simple Past Tense interrogative sentence.

Additional Information: Importance of Voice in English Grammar

Understanding active and passive voice is crucial for effective communication. While the active voice is generally preferred for its directness and clarity, the passive voice is useful in situations where:

• The doer of the action is unknown or unimportant (e.g., "The window was broken.").
• The action or the receiver of the action is more important than the doer (e.g., "The patient was successfully treated.").
• You want to avoid mentioning the doer (e.g., "Mistakes were made.").

Being able to convert sentences between active and passive voice demonstrates a strong grasp of grammatical structures and allows for greater flexibility in writing and speaking.
