add a comma, semicolon, or colon if needed. otherwise, submit the text without any additional punctuation.\n\nsince the national spelling bees inception in 1925, its winner has been determined by some rather unchallenging words knack (1928), initials (1941), and luge (1984).
Answer
Explanation:
To determine the appropriate punctuation, we analyze the sentence structure. The part after "words" is providing examples of the "unchallenging words" mentioned. A colon is used to introduce a list of examples or explanations. So we use a colon here.
Step1: Analyze the sentence purpose
The sentence is introducing examples of "unchallenging words" after the phrase "some rather unchallenging words".
Step2: Choose the correct punctuation
A colon (:) is suitable to introduce the list of examples (knack (1928), initials (1941), and luge (1984)). So we insert a colon in the blank.
Answer:
Since the National Spelling Bee's inception in 1925, its winner has been determined by some rather unchallenging words: knack (1928), initials (1941), and luge (1984).
