Select the option that expresses the given sentence in passive voice.
The district hospital is going to install a new MRI machine next month.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A new MRI machine is going to be installed by the district hospital next month.
Passive of be going to + verb:
| Change | Active | Passive | Why |
|---|---|---|---|
| Object becomes subject | a new MRI machine | A new MRI machine | The machine receives the action, so it becomes the subject. |
| Plan kept | is going to install | is going to be installed | “Is going to install” shows a plan. The passive keeps the plan: is / are going to be + past participle (V3). “Is” because there is one machine. |
| Agent (by ...) | The district hospital | by the district hospital | The hospital is named, so the doer comes after “by”. |
| Full sentence | The district hospital is going to install a new MRI machine next month. | A new MRI machine is going to be installed by the district hospital next month. |
“Was going to” changes the same way: was / were going to + verb → was / were going to be + V3. Example: Nani was going to repaint the front door. → The front door was going to be repainted by Nani.
Why the Other Options are Incorrect?
Option 1: A new MRI machine is going to install by the district hospital next month. — Incorrect. “Be” and the V3 are missing. “Is going to install” is active, as if the machine will do the installing.
Option 2: A new MRI machine was going to be installed by the district hospital next month. — Incorrect. “Was” puts the plan in the past. The active “is going to” is in the present.
Option 4: Next month, a new MRI machine are going to be installed by the district hospital. — Incorrect. “Are” does not agree with the singular “machine”. It must be “is”.
