Select the option that expresses the given sentence in passive voice.
They will have to pull down this building as they have not complied with the building regulations of the city.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e.:“This building will have to be pulled down by them as the building regulations of the city have not been complied with.”
**Future obligation in passive**:
The original sentence uses a modal-like construction:
“They will have to pull down…” indicating future necessity or obligation.
When converted to passive, “will have to” + “be” + past participle is preserved:
This building will have to be pulled down by them.
**Compliance clause in passive**:
The second part, “…they have not complied with the building regulations of the city,” becomes passive as:
“…the building regulations of the city have not been complied with.”
This correct passive form, have been complied with, aligns with standard passive rules for present perfect tense .
Why the other options are incorrect:
Option 2: “needs to be pulled down” — changes the modal meaning from obligation (“will have to”) to suggestion/necessity (“needs to”).
Option 3: “will be pulled down” — simply predicts future action, missing the element of obligation (“have to”).
Option 4: “is to be pulled down” — implies plan or arrangement rather than obligation following from non-compliance; slightly off in nuance.
