Error Spotting – Choose the part (A–D) that contains the grammatical error, or choose No error if the sentence is fully correct. Sentence (parts correspond to options below): A) All of you will agree with me B) that no problem faced by our society C) is as grave and intractable D) as this problem is

Introduction / Context:This question tests comparison structure with as … as and the avoidance of superfluous verbs in the second as-clause. In formal written English, the verb be after the second as is usually omitted when it does not add meaning.

Given Data / Assumptions:

• Comparator frame: as grave and intractable … as
• Second term of comparison: this problem
• Extra copula: is at the end of the sentence

Concept / Approach:In as … as comparisons, a repeated be after the second as is often unnecessary. The idiomatic form is as … as + noun/pronoun without an extra is. Keeping is produces awkward redundancy without changing meaning.

Step-by-Step Solution:

Verification / Alternative check:Paraphrase: No problem is as serious as this problem. The natural end point is a noun phrase, not a verb phrase, confirming that is is superfluous here.

Why Other Options Are Wrong:

• A) Standard preface to an assertion; grammatical.
• B) Relative clause faced by our society is correctly formed.
• C) Predicate adjectives grave and intractable are fine.

Common Pitfalls:Learners sometimes mirror earlier be-forms and add another be at the end of a comparison. Keep the structure lean: as + adjective + as + noun/pronoun.

Final Answer:Option D contains the error. Use as this problem (omit is).
