Directions: In each of the following questions there are three blank spaces. Below each question there are some options and each option consist of three words which can be filled up in the blanks of the statement(s) to make the statement grammatically correct. Choose the correct alternative among the options given below. His ________ speech at the conference ________ the audience and ________ his deep knowledge on the subject.

### Concept & Vocabulary In Context Determine the overall tone of the sentence. The phrase "deep knowledge" establishes a strongly positive tone, indicating that the preceding descriptive words must also carry positive connotations. ### Step-by-Step Solution - **First blank:** Requires an adjective describing an impressive, well-received speech. "Eloquent" (fluent or persuasive in speaking or writing) is an excellent fit. - **Second blank:** Requires a verb describing a positive, engaging effect on the audience. "Captivated" (attract and hold the interest and attention of) fits perfectly. - **Third blank:** Requires a verb indicating how he presented his knowledge to the audience. "Conveyed" (make an idea, impression, or feeling known or understandable to someone) completes the thought logically. - Let's evaluate others based on tone: (a) "intimidated" is negative. (c) "repelled" is negative. (e) "strengthen" is grammatically incorrect (needs past tense). ### Exam Strategy & Shortcut Use tone to rapidly eliminate options. Since the sentence clearly praises the speaker's knowledge, eliminate any option containing negative words like "intimidated", "incapacitated", or "repelled". Option (d) is the only consistently positive choice. ### Common Pitfall Failing to check for grammatical consistency across blanks. For instance, in option (e), the verb "strengthen" is present tense, which breaks the past tense structure established by the context. ### Final Answer Therefore, the correct answer is **D**.
