Understanding the Sentence Correction Task

The question asks us to identify incorrectly placed words within a given sentence and determine which words need to be interchanged to make the sentence grammatically correct and meaningful. We are given four bold words in the sentence, labeled A, B, C, and D, and we need to select the option that shows the correct order of these words after interchanging if necessary. If no interchange is needed, the 'No Error' option should be chosen.

The original sentence is:

Amisha was sewerage (A) by the dearth (B) of a proper unnerved (C) system in the barbaric (D) village.

Let's look at the bold words and their typical meanings:

• Sewerage (A): Refers to the system of sewers or the removal of waste water and human excreta. It is typically a noun.
• Dearth (B): A scarcity or lack of something. This is a noun, often used with "of".
• Unnerved (C): Caused someone to lose confidence or feel apprehensive or disconcerted. This is typically a past participle used as an adjective (describing Amisha's state) or part of a verb phrase.
• Barbaric (D): Savagely cruel; primitive; uncivilized. This is an adjective describing the village.

Reading the original sentence, "Amisha was sewerage..." doesn't make sense because 'sewerage' is not typically a state of being for a person. "unnerved system" also sounds incorrect; a system is not usually described as 'unnerved'. "dearth of a proper unnerved system" is also awkward. The sentence structure suggests Amisha was affected (adjective/verb) by something (noun/lack) related to a type of system (noun) in a type of village (adjective).

Analyzing the Options for Word Interchange

We need to see which arrangement of the words A, B, C, and D results in a logical sentence. The options suggest possible new orders for the words originally at positions A, B, C, and D.

The correct option provided is CBAD. This means the word originally at position C ("unnerved") should go first, followed by the word originally at B ("dearth"), then the word originally at A ("sewerage"), and finally the word originally at D ("barbaric").

Let's reconstruct the sentence with the words in the order C, B, A, D:

Word at C (unnerved) → Word at B (dearth) → Word at A (sewerage) → Word at D (barbaric)

New Sentence: Amisha was unnerved by the dearth of a proper sewerage system in the barbaric village.

Evaluating the Rearranged Sentence

Let's examine the rearranged sentence:

"Amisha was unnerved by the dearth of a proper sewerage system in the barbaric village."

• "Amisha was unnerved": This is grammatically correct and makes sense. 'Unnerved' describes Amisha's state of feeling disturbed or disconcerted.
• "by the dearth of a proper sewerage system": This phrase is also correct. 'Dearth' means lack, and "dearth of a proper sewerage system" means there was a lack of a suitable waste disposal system.
• "in the barbaric village": This is correct, describing the location as a primitive or uncivilized village.

The complete sentence, "Amisha was unnerved by the dearth of a proper sewerage system in the barbaric village," is grammatically sound and meaningful. It conveys that Amisha was disturbed because the uncivilized village lacked a proper waste disposal system.

Identifying the Correct Interchange

Comparing the original sentence with the correct one, we can see which words were moved:

• Original: Amisha was sewerage (A) by the dearth (B) of a proper unnerved (C) system in the barbaric (D) village.
• Correct: Amisha was unnerved (C's word) by the dearth (B's word) of a proper sewerage (A's word) system in the barbaric (D's word) village.

The word originally at A ('sewerage') moved to C's position, and the word originally at C ('unnerved') moved to A's position. Words at B ('dearth') and D ('barbaric') remained in their relative positions within the sequence, although the whole sequence was rearranged according to the CBAD pattern.

The required interchange involves swapping the words at positions A and C.

Conclusion

By interchanging the words 'sewerage' (A) and 'unnerved' (C), and following the order specified by CBAD, the sentence becomes logical and grammatically correct. The correct order of the original words A, B, C, and D is C, B, A, D.
