Choose the option that is most nearly opposite in meaning to the underlined word and that will correctly fill…

Step 1: Analyze the question The sentence is: "While other teachers' support for the action was ...., Victor's was dogged." The underlined word is dogged, and we need its opposite that also fits the gap.

Step 2: Understand the concept

• Dogged means stubbornly persistent, firm, unyielding.
• The word "While" signals contrast. Victor's support was firm and unwavering, so the other teachers' support must have been the opposite: unsteady, hesitant, not firm.

Step 3: Test the options

• A. declining: means decreasing. It suggests a reduction over time, not the direct opposite of persistence, so it is a weak fit.
• B. disappointing: describes the quality of the support, but it is not an antonym of dogged.
• C. wavering: means hesitating or being unsteady, the direct opposite of firm and persistent. It fits the contrast perfectly.
• D. woeful: means very bad or sorrowful, which has nothing to do with persistence.

Step 4: Answer The best option is C. wavering. It is the closest opposite of dogged and makes the sentence logical: "While other teachers' support for the action was wavering, Victor's was dogged."

Tip: In "opposite meaning + fill the gap" questions, look for contrast words like while, but, although, whereas. They tell you the missing word must contrast with the given one. Also learn some synonyms for dogged: tenacious, resolute, persistent, steadfast. Their opposites include wavering, hesitant, irresolute.
