D.before he walked down the street he checked to make sure the new kid wasn"t there.

Which answer did you pick?

Right.

The correct sentence that demonstrates proper comma usage is option C: "By the end of the first stanza, I had guessed that the new kid was a girl."

To determine the correct comma usage, let's review the rules. Commas are used in several different scenarios, including:

1. To separate items in a list: For example, "I bought apples, oranges, and bananas."
2. To separate independent clauses joined by coordinating conjunctions: For example, "She likes to read, and he enjoys playing sports."
3. To set off introductory words or phrases: For example, "In conclusion, I want to thank everyone for their support."
4. To offset nonessential information or clauses: For example, "The new girl, who recently moved here, seems friendly."

Now, let's analyze the given options:

A. "Yes, I enjoy writing poetry in my spare time." - This sentence uses the correct comma placement to separate the introductory word "Yes" from the rest of the sentence.

B. "After, a while, I suppose, the boy became less scared of the new girl." - This sentence does not have correct comma usage. The commas are placed inconsistently and do not follow any specific grammar rules.

C. "By the end of the first stanza, I had guessed that the new kid was a girl." - This sentence is correctly using a comma to separate the introductory phrase "By the end of the first stanza" from the main clause.

D. "Before he walked down the street, he checked to make sure the new kid wasn't there." - This sentence uses a comma correctly to separate the introductory clause "Before he walked down the street" from the main clause.

Based on the analysis, options A and C demonstrate proper comma usage. However, the sentence in option C is more complex and exhibits the correct placement of a comma to separate an introductory phrase, making it the better choice.
