Question

Difficulty: MediumAntonyms and Words Opposite in Meaning

Complete the sentence below by filling in the blank with a word that is MOST NEARLY OPPOSITE in meaning to the capitalized word.

Answer:Although the lead researcher's initial presentation was praised for being extraordinarily LUCID, the final technical report offered an explanation so 【obscure】 that very few members of the review panel could follow it.

Answer

The word opposite in meaning to 'LUCID' in this context is 'obscure' (or accepted contextual equivalents such as 'convoluted', 'abstruse', or 'ambiguous').
In the context of the sentence, 'lucid' means clear, coherent, and easy to understand. The contrasting transition word 'Although' signals that the condition of the final report stands in opposition to the initial presentation. Therefore, the blank requires a word meaning unclear, complicated, or difficult to understand, such as 'obscure', 'convoluted', or 'abstruse'.

Step-by-Step Solution

1
Determine the contextual meaning of the capitalized target word 'LUCID'.
'Lucid' means expressed clearly, transparent, or easy to understand.
Identifying the target word's specific meaning in context is necessary before finding its opposite.
2
Analyze the sentence structure for contextual contrast cues.
The subordinating conjunction 'Although' sets up a contrast between the initial presentation ('lucid') and the final technical report, which 'very few members... could follow'.
The sentence logic dictates that the blank must contain a word describing something hard to comprehend.
3
Identify an appropriate antonym that fits both syntactically and semantically.
'Obscure' directly opposes 'lucid' by meaning hard to understand, indistinct, or unclear.
Filling the blank with 'obscure' satisfies the required contrast and completes the grammatical structure.
