Question

Identify the correct 'passive construction' of the following sentence : 
They laughed at his warnings and objected to all his proposals.

Accepted Answer

His warnings were laughed at and all his proposals were objected to.

**Explanation:**

Option 3, "His warnings were laughed at and all his proposals were objected to," is the correct passive construction because it transforms the original active voice sentence into a passive voice sentence while maintaining the original meaning. Here's why:

*   **Passive Voice Formation:** The passive voice is formed using a form of the verb "to be" (in this case, "were") followed by the past participle of the main verb (e.g., "laughed," "objected"). The subject of the active sentence ("They") becomes the agent (often omitted or placed in a "by" phrase, which is not necessary here for a grammatically correct passive construction). The object of the active sentence ("his warnings" and "all his proposals") becomes the subject of the passive sentence.

*   **Correct Transformation:** The original sentence has two clauses: "They laughed at his warnings" and "They objected to all his proposals." In the passive construction, these become:
    *   "His warnings were laughed at" (passive of "They laughed at his warnings")
    *   "All his proposals were objected to" (passive of "They objected to all his proposals")

*   **Preservation of Meaning:** The passive construction accurately conveys the same information as the active sentence. The focus shifts from the actors ("They") to the actions performed on "his warnings" and "all his proposals."

**Why the other options are incorrect:**

*   **Option 1: They laughed and objected to his warnings and proposals respectively.** This option is in the active voice, not the passive voice. It simply rephrases the original sentence without changing the voice. "Respectively" is used correctly, but the sentence doesn't address the question's requirement for a passive construction.

*   **Option 2: At his warnings, they laughed and to all his proposals, they objected.** This option is also in the active voice. It rearranges the sentence structure but does not transform it into the passive voice. It's simply a stylistic variation of the active sentence.

*   **Option 4: At his warnings, they were laughing and to all his proposals, they were objecting.** This option uses the past continuous tense ("were laughing," "were objecting"), which changes the meaning and tense of the original sentence. The original sentence implies a completed action, while this option suggests an ongoing action. Furthermore, it remains in the active voice, not the passive voice.
