I'll be glad to check your answers.

To determine the correct comma usage in each sentence, we need to follow the rules of punctuation and grammar. Let's analyze each sentence:

7. Correct comma usage is shown in Option C: "By the end of the first stanza, I had guessed that the new kid was a girl." This sentence correctly uses a comma after the introductory phrase "By the end of the first stanza" to separate it from the main clause "I had guessed that the new kid was a girl."

Option A ("Yes i enjoy writing poetry in my spare time.") is incorrect because it does not include a comma after the introductory word "Yes."

Option B ("After, a while, i suppose, the boy became less scared of the new girl.") is incorrect because it uses commas indiscriminately, leading to unnecessary and incorrect punctuation.

Option D ("Before he walked down the street he checked to make sure the new kid wasn't there.") is incorrect because it does not include a comma to separate the introductory clause "Before he walked down the street."

8. Correct comma usage is shown in Option B: "The girl, unlike the boy, is a new kid on the block." This sentence correctly uses commas to set off the nonessential clause "unlike the boy."

Option A ("This poem, by the way, has two long stanzas.") is correct in terms of comma usage, as it adds a parenthetical phrase "by the way" and sets it off with commas, but it is incorrect in terms of punctuation. The phrase "This poem, by the way" should be separated from the rest of the sentence with a period, not a comma.

Option C ("The boy, as the poem says, doesn't care for her at all.") is incorrect because it uses unnecessary commas around the phrase "as the poem says."

Option D ("The poem, in my opinion, has a funny ending.") is incorrect because it incorrectly places a comma after the introductory phrase "The poem" without any additional needed punctuation.

Therefore, the correct answers are:

7. Option C: "By the end of the first stanza, I had guessed that the new kid was a girl."

8. Option B: "The girl, unlike the boy, is a new kid on the block."
