Choose the right alternative to fill in the blank :
_____ the book, I returned it to the library.

Question

Accepted Answer

Option 2, "Having Read," is the correct choice to fill in the blank because it accurately conveys the sequence of events in the sentence. The phrase "Having Read" is a perfect participle, which is used to indicate that one action was completed before another action took place. In this context, it means that the action of reading the book was completed before the action of returning it to the library. This sequence is logically consistent with the intended meaning of the sentence.

Now, let's examine why the other options are incorrect:

1. **Reading**: This option suggests that the action of reading and returning the book happened simultaneously, which does not logically fit the context of the sentence. The sentence implies that the book was read completely before it was returned, not during the act of returning.

3. **Will Read**: This option indicates a future action, which does not align with the past tense context of the sentence. The sentence clearly describes a sequence of past events, so using a future tense form is inappropriate.

4. **Read**: While this option is in the past tense, it does not convey the completion of the action before the next action took place. It lacks the perfect aspect that "Having Read" provides, which is necessary to show that the reading was completed prior to returning the book.

In summary, "Having Read" is the only option that correctly indicates the completion of one action before another, making it the appropriate choice for the sentence.
