Change Voice: Passive to Active

The task is to change the voice of the given English sentence from Passive Voice to Active Voice. We need to analyze the original sentence, understand the rules of voice change, and then evaluate the provided options to find the correct Active Voice transformation.

Original Sentence Details

The sentence we need to transform is:

"The satellite has been launched successfully by ISRO."

  • Voice: This sentence is in the Passive Voice. The subject ("The satellite") is receiving the action.
  • Tense: The tense is the Present Perfect Passive, indicated by "has been launched".
  • Components:
    • Subject: The satellite
    • Verb Phrase: has been launched
    • Adverb: successfully
    • Agent (doer of the action): ISRO (mentioned after "by")

Voice Conversion Rules

To convert a sentence from Passive Voice to Active Voice, especially in the Present Perfect Tense, we follow these key steps:

  1. The subject of the passive sentence becomes the object of the active sentence.
  2. The agent (the noun phrase following "by" in the passive sentence) becomes the subject of the active sentence.
  3. The passive verb phrase (has/have + been + past participle) is converted into the active verb phrase (has/have + past participle).
  4. Ensure the subject and verb agree in number (singular/plural).

Applying Rules to ISRO Satellite Sentence

Let's apply these rules to our sentence:

  1. Identify the agent: The agent is "ISRO". This will become the new subject.
  2. Identify the passive subject: The passive subject is "The satellite". This will become the new object.
  3. Convert the verb: The passive verb phrase is "has been launched". Since "ISRO" is singular, the active Present Perfect verb phrase will be "has launched".
  4. Include the adverb: The adverb "successfully" modifies the verb and should be placed correctly.
  5. Form the active sentence: Combining these parts gives us: "ISRO" (subject) + "has launched" (verb) + "the satellite" (object) + "successfully" (adverb).

The resulting Active Voice sentence is: ISRO has launched the satellite successfully.

Option Evaluation

We will now examine each provided option to see which one correctly reflects this transformation:

Option Number Sentence Option Evaluation
1 ISRO have launched the satellite successfully. This option has incorrect subject-verb agreement. "ISRO" is singular, requiring "has", not "have".
2 ISRO has launched the satellite successfully. This option correctly converts the sentence to Active Voice (Present Perfect). It uses the correct subject ("ISRO"), verb ("has launched"), object ("the satellite"), and adverb ("successfully"), maintaining proper grammar.
3 ISRO has launch the satellite successfully. This option uses the incorrect verb form. After "has", the past participle "launched" is needed, not the base form "launch".
4 ISRO has launched the satellite successful. This option uses the incorrect word form. The adverb "successfully" is needed to modify the verb, not the adjective "successful".

Conclusion on Correct Voice Change

After analyzing the original sentence and evaluating all the options based on the rules of English grammar for voice transformation, the sentence "ISRO has launched the satellite successfully." is the correct Active Voice version of the given Passive Voice sentence.
