Which sentence is punctuated incorrectly?

A:Kenneth Grahame's novel "The Wind in the Willows" was first published in 1908.
B:Kenneth Grahame's novel The Winds in the Willows<-(this is underlined) was first published in 1908.
C:Kenneth Grahame's novel The Winds in the Willows<-(this is italicized) was first published in 1908.
D:The Winds in the Willows<-(this is italicized), Kenneth Grahame's novel, was first published in 1908.

Just checking the first one. For the second, I saw that the incorrectly punctuated sentence is A. Why is this the case over B? (I know it's not C or D)

For your second question, remember that titles of books, movies, plays, artwork, magazines, etc., need to be either underlined or in italics. A is the incorrectly punctuated sentence because of the quotation marks -- those are for items that can be published within something else: poems, song lyrics, magazine articles ...

And I agree with you that A is the incorrectly punctuated sentence for the first question. There doesn't need to be a hyphen between "internal" and "combustion" since the first is an adjective modifying the noun.

Ok I understand, thank you so much Writeacher

You're welcome.

A. He explained the principle of internal-combustion (although not very well.) is the incorrectly punctuated sentence.

The parentheses indicate an aside or additional information, and the period inside the parentheses is unnecessary. The correct punctuation would be: He explained the principle of internal-combustion (although not very well).

To determine which sentence is punctuated incorrectly in the first set of options, you can analyze the punctuation in each sentence individually.

A. He explained the principle of internal-combustion (although not very well.)
The punctuation in this sentence appears correct. The parentheses are used to provide additional information and are appropriately placed.

B. John Lennon (1940-1980) was a founding member of The Beatles.
The punctuation in this sentence appears correct as well. The parentheses are used to provide the dates of John Lennon's lifespan and are appropriately placed.

C. The Latin expression "per se" ("in itself") has found wide use in legal circles.
The punctuation in this sentence appears correct. The quotation marks are used to indicate the specific Latin expression and its translation, and they are appropriately placed.

D. Fredrick (not known as "Tex") was becoming a well-known animator.
The punctuation in this sentence is incorrect. The parentheses should not be used to provide this kind of additional information. Instead, a comma should be used: Fredrick, not known as "Tex," was becoming a well-known animator.

Therefore, the correct answer to the first question is D. Fredrick (not known as "Tex") was becoming a well-known animator.

Regarding the second question about why sentence A is incorrect over B, let's analyze the options:

A. Kenneth Grahame's novel "The Wind in the Willows" was first published in 1908.
The punctuation in this sentence appears correct. The title of the novel is enclosed in double quotation marks, which is a valid way to indicate a specific work's title.

B. Kenneth Grahame's novel The Winds in the Willows was first published in 1908.
In this sentence, the title of the novel should be enclosed in quotation marks or italicized to indicate it's a book title. Without any indication, this sentence is punctuated incorrectly.

Therefore, the correct answer to the second question is B. Kenneth Grahame's novel The Winds in the Willows<-(this is underlined) was first published in 1908.
