Active and Passive Voice Analysis

The question asks to identify which of the given pairs correctly transform sentences from Active Voice to Passive Voice.

Analyzing Pair I

Active Voice: "They laughed at his warnings and objected to all his proposals."

Passive Voice: "His warnings were laughed at and his proposals were objected to."

• The verbs "laughed at" and "objected to" are verb-preposition combinations that function similarly to phrasal verbs in this context.
• In the passive voice, the preposition must remain attached to the verb.
• The transformation correctly uses "were laughed at" and "were objected to", maintaining the prepositions.
• Therefore, Pair I shows a correct transformation.

Analyzing Pair II

Active Voice: "Do not insult the weak." (This is a negative imperative sentence).

Passive Voice: "You are advised to not insult the weak."

• Negative imperative sentences can be converted into the passive voice using structures like "You are advised/requested/ordered not to..."
• The standard grammatical form for the infinitive is "not to + verb" (e.g., "not to insult").
• The provided passive voice uses "to not insult". While the meaning is conveyed, the conventional structure is "You are advised not to insult the weak."
• Due to this structural nuance in the infinitive phrase, Pair II might be considered incorrectly transformed.

Conclusion

Based on the analysis:

• Pair I is correctly transformed into the passive voice.
• Pair II presents a less standard grammatical structure for the passive transformation of a negative imperative.

Therefore, only Pair I is correctly stated in the passive voice.
