Final answer:
To correctly punctuate the sentence, it should include an apostrophe in "who's", an apostrophe in "evening's", and end with a question mark.
Step-by-step explanation:
The correctly punctuated sentence should read: "Guess who's coming to this evening's dinner?". The sentence requires an apostrophe in "who's" to indicate a contraction of "who is".
Additionally, "evening's" needs an apostrophe to show possession, indicating that the dinner belongs to the evening. Lastly, the sentence should end with a question mark since it is a direct question being posed.
"Guess who's coming to this evening's dinner?" punctuates the sentence correctly. The contraction "who's" combines "who is," conveying anticipation about the dinner guest. The apostrophe in "evening's" signifies possession, indicating the dinner belonging to the evening.
The sentence, through proper punctuation, prompts the reader to speculate about the anticipated guest, creating a sense of curiosity and engagement. It showcases the importance of punctuation in conveying meaning and clarity, enhancing written communication by accurately reflecting the intended structure and tone
