In the following question, a sentence is divided into numbered parts. Identify the part that contains an error in adverb form. Sentence: “When the self is not enlightened, it is fundamental identified with the notion of difference, unaware of its primordial unity.”

Introduction / Context:
This question examines the correct use of adjective and adverb forms in a sentence about the unenlightened self. The sentence is divided into parts, and one part contains a word form error. The phrase “fundamental identified” in part (2) appears to be grammatically wrong and must be checked carefully.

Given Data / Assumptions:

• The sentence is: “When the self is not enlightened, it is fundamental identified with the notion of difference, unaware of its primordial unity.”
• Part (1) likely contains “When the self is not enlightened.”
• Part (2) contains “it is fundamental identified with the notion of difference.”
• Part (3) contains “unaware of its primordial unity.”
• The structure “is identified” takes an adverb when modified, so “fundamentally identified” is expected, not “fundamental identified.”

Concept / Approach:
The concept here is distinguishing between adjectives and adverbs. “Fundamental” is an adjective and normally describes nouns, whereas “fundamentally” is an adverb that modifies verbs or entire clauses. Since “identified” is a verb in the passive construction “is identified,” any word modifying it must be an adverb. Therefore, “fundamentally identified” is correct, and “fundamental identified” is incorrect.

Step-by-Step Solution:

Verification / Alternative check:
Rewrite the sentence correctly: “When the self is not enlightened, it is fundamentally identified with the notion of difference, unaware of its primordial unity.” Now the adverb “fundamentally” properly modifies the passive verb phrase “is identified,” and the sentence flows naturally. Since this correction concerns only part (2), the error is verified.

Why Other Options Are Wrong:

• Part (1): The clause “When the self is not enlightened” is grammatically correct and sets the condition clearly.
• Part (3): The phrase “unaware of its primordial unity” correctly uses the adjective “unaware” to describe the self.
• “No error”: This option is wrong because the form “fundamental identified” is not standard English in this construction.

Common Pitfalls:
Some learners confuse when to use adjective or adverb forms, especially when the word endings are similar. Others may not pay attention to the difference between describing a noun and modifying a verb. A reliable strategy is to identify whether the word following “is” is a participle functioning as a verb or as a complement. In “is identified,” “identified” is clearly a verb form, so the modifier must be an adverb like “fundamentally.”

Final Answer:
Part (2) is the correct answer, because “fundamental identified” should be corrected to “fundamentally identified.”
