Question

Choose the correct word to complete the sentence: His speech was so _ _ _ _ that everyone lost interest halfway through.

• A. Engaging
• B. Monotonous
• C. Lively
• D. Exciting

Hint:

In sentence-completion questions, always focus on context clues. Expressions such as “so ... that”, “because”, “therefore”, and “as a result” often reveal whether the missing word should carry a positive or negative meaning. Matching the tone of the blank with the outcome stated in the sentence helps eliminate incorrect options quickly.

Answer 1

The Correct Option is B

Concept: In vocabulary-based fill-in-the-blank questions, the correct answer is determined by carefully analyzing the context of the sentence and identifying the relationship between the blank and the information that follows. One of the most important contextual clues in English grammar and vocabulary is the structure “so ... that”, which indicates a cause-and-effect relationship. In the given sentence, the result is clearly stated: “everyone lost interest halfway through” Therefore, the missing word must describe a quality of the speech that would naturally cause listeners to become bored, inattentive, or uninterested. To arrive at the correct answer, each option must be examined individually and compared with the overall meaning of the sentence.

Step 1: Analyze the contextual clue provided in the sentence. The sentence states: “His speech was so _ _ _ _ that everyone lost interest halfway through.” The phrase “lost interest” conveys a negative reaction from the audience. It suggests that the speech failed to maintain attention and was probably dull, repetitive, or uninteresting. Hence, the word filling the blank should have a negative meaning associated with boredom or lack of variety.

Step 2: Evaluate Option (A) -- Engaging. The word Engaging means:
• Interesting
• Attractive
• Able to capture and hold attention
• Pleasant and enjoyable Example: “The teacher gave an engaging presentation that kept the students attentive throughout the class.” If a speech is engaging, listeners usually become more interested rather than losing interest. Thus, the statement “His speech was so engaging that everyone lost interest halfway through.” creates a contradiction. Therefore, Option (A) is incorrect.

Step 3: Evaluate Option (B) -- Monotonous. The word Monotonous refers to something that is:
• Repetitive
• Lacking variety
• Dull
• Tedious
• Unchanging in tone or style Example: “The lecture became monotonous because the speaker continued repeating the same points.” A monotonous speech often causes listeners to lose concentration and become bored because there is little variation in delivery, content, or tone. Substituting the word into the sentence: “His speech was so monotonous that everyone lost interest halfway through.” The sentence now becomes perfectly logical and meaningful. Therefore, Option (B) is a strong match for the given context.

Step 4: Evaluate Option (C) -- Lively. The word Lively means:
• Energetic
• Animated
• Full of enthusiasm
• Interesting and active Example: “The lively discussion encouraged everyone to participate actively.” A lively speech generally increases audience involvement and attention. Thus, the statement “His speech was so lively that everyone lost interest halfway through.” does not make logical sense. Hence, Option (C) is incorrect.

Step 5: Evaluate Option (D) -- Exciting. The word Exciting means:
• Thrilling
• Stimulating
• Interesting
• Capable of creating enthusiasm Example: “The exciting announcement captured everyone's attention immediately.” An exciting speech would normally make people more attentive rather than causing them to lose interest. Therefore, “His speech was so exciting that everyone lost interest halfway through.” is illogical. Hence, Option (D) is incorrect.

Step 6: Determine the most appropriate answer. After examining all four options, we observe:
• Engaging $\rightarrow$ Positive meaning; contradicts the result.
• Monotonous $\rightarrow$ Dull and repetitive; perfectly explains the result.
• Lively $\rightarrow$ Positive meaning; contradicts the result.
• Exciting $\rightarrow$ Positive meaning; contradicts the result. Therefore, the only word that logically fits the context is: \[ \boxed{\text{Monotonous}} \] Hence, the correct answer is Option (B).
