In this English grammar error-spotting question, identify which part of the sentence contains the error in the correlative pattern and comparison: "It is not (A) such a pretty place (B) that I had expected. (C) No Error. (D)". Choose the option that marks the incorrect segment or select 'No Error' if the sentence is fully correct.

Introduction / Context:
This question tests your understanding of correlative structures and comparative expressions in English. The sentence attempts to compare the actual attractiveness of a place with the level of attractiveness the speaker had expected. Correctly pairing words such as "such" and "as" or "as" and "as" is essential for natural and accurate expression in English grammar.

Given Data / Assumptions:

• Sentence: "It is not such a pretty place that I had expected."
• Part A: "It is not"
• Part B: "such a pretty place"
• Part C: "that I had expected."
• Part D: indicates "No Error".
• The intended meaning is: "The place is not as pretty as I had expected."

Concept / Approach:
English uses specific patterns for comparisons. When we say that something does not meet our expectations in degree, a very common pattern is "not as + adjective + as". For example, "It is not as beautiful as I expected." The phrase "such a pretty place that I had expected" is incorrect because "such...that" is normally used to express result, as in "such a pretty place that everyone admired it", not to compare with expectations. Therefore, Part C should contain "as I had expected", not "that I had expected".

Step-by-Step Solution:
Step 1: Look at Part A: "It is not". This correctly introduces a negative statement. Step 2: Look at Part B: "such a pretty place". On its own, this phrase is grammatically correct and can be part of either a "such...that" result structure or another construction. Step 3: Look at Part C: "that I had expected." When combined with "It is not such a pretty place", using "that" is incorrect for expressing a comparison with what was expected. Step 4: The sentence should be recast as either "It is not as pretty a place as I had expected" or more simply "It is not as pretty as I had expected." Step 5: Thus, the error lies in Part C, where "that" should be replaced with "as" to form the "as...as" comparison pattern.

Verification / Alternative check:
Compare the original sentence with a corrected one: "It is not such a pretty place that I had expected" versus "It is not as pretty a place as I had expected." The corrected sentence clearly communicates that the actual prettiness is less than what was anticipated. The original sentence feels awkward and grammatically off to native speakers. This contrast shows that Part C, containing "that I had expected", is incorrect in this context.

Why Other Options Are Wrong:

• Part A: "It is not" is an accurate and standard way to begin the negative statement.
• Part B: "such a pretty place" is structurally fine and could be used properly if the rest of the structure were changed into a result clause ("such a pretty place that everyone loved it"). The main issue is not here.
• Part D (No Error): Cannot be selected because the conjunction in Part C is wrong for this comparative meaning.
• Error in more than one part: Not correct, since A and B can stand in a suitably restructured sentence; the core problem is the incorrect use of "that" in Part C.

Common Pitfalls:
Many learners confuse "such...that" and "so...that" result clauses with comparative "as...as" patterns. "Such...that" is used to show a result, for example, "It was such a hot day that we stayed indoors." However, "not as...as" is used to say something is less than expected or less than something else: "The book is not as interesting as the film." Mixing these patterns leads to sentences that are grammatically flawed and semantically unclear. In exams, paying attention to the exact relationship being expressed—result versus comparison—will help you choose the correct structure.

Final Answer:
The erroneous segment is Part C: "that I had expected."; it should be "as I had expected", giving "It is not as pretty a place as I had expected.".
