The governor's visit is an unprecedented event in the history of the social club

Step 1: Analyze the question The italicized word is "unprecedented" (the "an" in the options suggests the phrase is "an unprecedented"). We need the option that is opposite in meaning.

Step 2: Meaning of the word Unprecedented means never having happened or existed before. It describes something exceptional, remarkable, or without a parallel. Its opposites would be words like usual, ordinary, commonplace, or unremarkable.

Step 3: Test each option

• A. a perfect: This is about flawlessness, not about whether something has happened before. It is not an opposite.
• B. momentous: This means very important or significant. It is close to a synonym of "unprecedented" in this context, so it is wrong.
• C. an insignificant: This means unimportant or trivial. It is the opposite of an exceptional, remarkable event.
• D. an unnecessary: This is about need, not about how remarkable the event is. It is not an opposite.

Step 4: Note on the question The ideal opposite would be "commonplace" or "usual", and neither is offered. Of the options, "insignificant" is the nearest in meaning, because it describes an unremarkable event.

Answer: C. an insignificant

Exam tip: In "opposite meaning" questions, first eliminate any option that is a synonym (here, momentous). Then pick the option that best reverses the core idea, which here is "exceptional and remarkable" versus "unimportant". Also, don't pick an option just because it sounds positive or negative.
