Select the sentence that uses hyphenation correctly in compound modifiers.
Answer and explanation
Correct answer: A. The university unveiled a state-of-the-art laboratory for renewable energy research.
- Step 1: Compound adjectives preceding a noun ('laboratory') must be hyphenated to function as a unit: 'state-of-the-art'. Step 2. The hyphenation stops before the noun being modified. Answer: The university unveiled a state-of-the-art laboratory for renewable energy research. Why not the others: Leaving the compound unhyphenated creates ambiguity; hyphenating through to the noun is improper.
