Select the sentence which is meaningful and grammatically correct.
To identify a grammatically correct and meaningful sentence, we need to consider the standard English sentence structure, which typically follows the order: Subject + Verb + Object + Adverbials (like place, time, manner).
Let's examine each option:
This sentence has a very unnatural word order. It starts with adverbial phrases ("On the Delhi Meerut Expressway since January") before the subject ("the government") and verb ("has levied"), and the object ("toll tax") is placed before the subject and verb. This structure is incorrect in standard English.
This sentence has the subject ("The government") and verb ("has levied") correctly placed at the beginning. However, the adverbial phrase of time ("since January") is placed before the adverbial phrase of place ("on the Delhi Meerut Expressway"), and the object ("toll tax") comes at the very end after both adverbial phrases. The natural order is usually Subject + Verb + Object + Place + Time. Placing the object after the adverbials makes the sentence awkward and grammatically questionable.
This sentence starts with the object ("Toll tax"). While object-fronting is sometimes used for emphasis, the rest of the sentence structure is disrupted. The subject ("the government") and verb ("has levied") are placed at the end after the adverbial phrases ("since January on the Delhi Meerut Expressway"), which is not a standard or natural structure for a simple declarative sentence like this.
This sentence follows the standard and most natural English sentence structure:
The order is Subject + Verb + Object + Place + Time, which is grammatically correct and makes the sentence clear and meaningful.
The fourth option demonstrates the most common and correct word order for this type of sentence. It clearly states who did what (The government levied toll tax), where they did it (on the Delhi Meerut Expressway), and when (since January). The other options deviate significantly from this standard structure, resulting in grammatically incorrect or awkward sentences.
