Sentence Arrangement Explanation

This question asks us to arrange the given phrases into a coherent and grammatically correct sentence. We need to identify the correct sequence of the parts provided.

Given Parts:

• (I) the station
• (II) reached
• (III) before noon
• (IV) they

Understanding Sentence Construction

To form a proper sentence, we typically follow a standard order, which often includes the subject, verb, object, and other modifiers like adverbials of time or place. Let's analyze each part:

Identifying Roles of Each Part:

• (IV) they: This is a pronoun and serves as the subject of the sentence, indicating who is performing the action.
• (II) reached: This is the past tense of the verb 'reach'. It represents the action performed by the subject.
• (I) the station: This noun phrase functions as the object of the verb 'reached', specifying the destination or what was reached.
• (III) before noon: This is an adverbial phrase that modifies the verb, indicating the time when the action occurred.

Assembling the Sentence

Based on the typical English sentence structure (Subject + Verb + Object + Adverbial of Time), we can assemble the parts:

Subject: (IV) they

Verb: (II) reached

Object: (I) the station

Adverbial of Time: (III) before noon

Combining these in the correct order gives us the sentence:

"They reached the station before noon."

Determining the Correct Sequence

The sequence that correctly represents this sentence structure is derived from the order of the numbered parts: (IV), (II), (I), (III).

Therefore, the correct sequence is IV, II, I, III.
