In the provided text from the Kay and Robert story "Brotherless," the punctuation needs to be corrected according to the editing guide given. Let's go step by step:
1. Capitalization:
- Start sentences with a capital letter.
- Proper nouns (like names) should be capitalized.
2. End Marks:
- Each sentence should end with the appropriate punctuation mark: period (.), question mark (?), or exclamation mark (!).
3. Commas:
- Use commas where necessary to separate parts of the sentence, like in lists or before conjunctions.
4. Quotation Marks:
- Use quotation marks at the beginning and end of direct speech.
Let's correct the text based on these guidelines:
Robert chuckled as he eyed his sister with respect. "Kay, I've decided to move on with my life," he said. "Besides, I know that it is to your advantage to have a brother," Robert declared airily. "Having a brother means that there are always boys around making goo-goo eyes at you."
"Oh, my! Have we increased our vocabulary since we discovered the dictionary?" retorted Kay.
