Fill in the blank in the following sentence with the most appropriate option:
She sent a recording of the class lecture, ______ by Professor Sinha
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → delivered
Complete sentence: She sent a recording of the class lecture, delivered by Professor Sinha. "The class lecture, (which was) delivered by Professor Sinha" describes the lecture, which the professor gave earlier.
| Option | Form and use | Example |
|---|---|---|
| (1) was delivered | A finite verb like "was delivered" needs which before it. Without it the sentence has two main verbs. | The lecture was delivered in the main hall. |
| (2) is delivered | It is a finite present form. It also needs "which" and does not match the past "sent". | The newspaper is delivered every morning. |
| (3) being delivered | an action in progress. The lecture was already over when its recording was sent. | The speech being delivered now is broadcast live. |
| (4) delivered (answer) | A clause like "which was delivered by ..." can be shortened by dropping which was. The past participle alone then describes the noun. | We read a speech delivered by Swami Vivekananda in Chicago. |
Contrast: delivered describes a finished action. Being delivered describes an action still going on.
