Analysis of the Sentences
- Sentence (A) is incorrect:
- The Error: "you are to obdurate..."
- The Correction: "To" is a preposition or part of an infinitive. To indicate "excessively" or "more than desired," the adverb "too" must be used.
- Corrected: Sometimes, you are too obdurate for your own good!
- Sentence (B) is incorrect:
- The Error: "...continued to wreaked havoc... and destroy..."
- The Correction: This sentence has a tense and parallelism conflict. After the word "to" (forming an infinitive), you must use the base form of the verb. Furthermore, "wreak" and "destroy" must be in the same form.
- Corrected: ...continued to wreak havoc on his crops and destroy the few healthy plants...
- Sentence (C) is incorrect:
- The Error: "Scratch your eye will not..."
- The Correction: The subject of a sentence must be a noun or a noun equivalent. A base verb like "scratch" cannot act as the subject. You must use a gerund (scratching) or an infinitive (to scratch).
- Corrected: Scratching your eye will not ameliorate the itching.
- Sentence (D) is CORRECT:
- The adjective "spectacular" correctly modifies the noun "display."
- The subject "display" (singular) matches the past tense verb "drew."
- "Thunderous applause" is a correct idiomatic expression.
