English grammar error-spotting (parallel comparison ‘‘as … as …’’ requires a like term): Read the sentence parts (A–D) and identify the error, ensuring the second ‘‘as’’ compares like with like: ‘‘Kamala's fountain-pen / is as expensive / as Shyama. / No error.’’

Given data

• A: ‘‘Kamala's fountain-pen’’
• B: ‘‘is as expensive’’
• C: ‘‘as Shyama.’’
• D: ‘‘No error.’’

Concept / Approach
Comparisons must be between comparable entities. Here, a pen is being compared to a person. The second term should be ‘‘Shyama's (fountain-pen)’’ or ‘‘the one Shyama owns’’.

Step-by-step check
Correct: ‘‘Kamala's fountain-pen is as expensive as Shyama's (pen).’’

Common pitfalls

• Omitting the possessive in the second term of comparison.

Final Answer
as Shyama.
