Question

Which sentence contains a punctuation error? A. Sixteen boys and nine girls registered for the community center's art class. B. Twelve of the twenty-four hikers forgot to bring sunscreen. C. The committee needs the following: forty five chairs, fifteen candles, and twenty yards of white muslin. D. Ninety-nine of a hundred people surveyed preferred the first candidate.

Answer 1

"C. The committee needs the following: forty five chairs, fifteen candles, and twenty yards of white muslin" contains a punctuation error since "forty-five" should be hyphenated. All numbers under 100 should in general by hyphenated.
