Key Concepts

Grammar

Grammar is the set of rules that govern the structure of sentences. In the context of the exercise, evaluating the options requires a keen eye on grammatical correctness. For example, grammar helps you understand why Option B ('Amazing the performances, it is that I know they') is confusing. The pronouns and verb placements do not follow standard grammar rules. On the other hand, Option C ('I am amazed by the performances that') correctly follows subject-verb-object structure and uses the appropriate tense.

Sentence Structure

Sentence structure is critical for conveying clear and concise messages. When evaluating the exercise options, pay attention to how words are arranged. Good sentence structure often includes:

• A clear subject or doer
• Proper verb placement
• A logical object

Option A lacks the necessary elements and context, making it hard to decipher. Option B misplaces its components, leading to confusion. Option D is fragmented and does not form a complete thought. Option C, however, follows a logical structure making it the best choice.

Clarity

Clarity in writing means making sure your message is easy to understand. When we look at exercise options, clarity helps us determine the most comprehensible choice. Option A ('NO CHANGE') might seem okay initially, but without a clear subject, it leaves the reader puzzled. Option B is unclear because it jumbles phrases without making sense. Option D is incomplete and thus lacks clarity. In contrast, Option C clearly states, 'I am amazed by the performances that', leaving the reader with a clear understanding of the sentence's intention.

Subject-Verb Agreement

Subject-verb agreement means the subject and verb in a sentence must match in number (singular or plural). This is a fundamental grammar rule. In the exercise, you can quickly see that Option B fails this rule because the subject 'performances' (which is plural) doesn't agree with the verbs and pronouns used ('it is that I know they'). Option D has a similar issue. Option C correctly matches the singular subject 'I' with the verb 'am' and the passive construction is grammatically correct and clear, making it the best choice.
