This sentence does not contain quotation marks where necessary: song titles should always be surrounded by quotation marks. Note that you should not add a comma before the song title and that ending punctuation (in this case, the period) should always be on the inside of quotation marks. The correct choice is, "her friends loved listening to the song "Hey Jude." "

This sentence does not contain quotation marks where it is necessary. Since the word "Spring" is the name of the poem, it should be in quotations. Note: it is books and complete works that should be underlined or italicized and you should never underline/italicize and quote a title. Also note that one choice is incorrect because the comma appears on the outside of the quotation marks after the word "Spring." Ending punctuation must always appear inside of quotation marks. The correct choice is, "The title of the poem, "Spring," confused many of the students."

This sentence misuses quotation marks. Titles of full books should never be surrounded by quotation marks; they should be italicized or underlined. The choice that fixes this issue is, "the book To Kill A Mockingbird is a literary classic."

This sentence does not use quotation marks where necessary. Quotation marks are always used around the titles of short stories, poems, excerpts, and so on. Note that ending punctuation should appear within quotation marks, so the comma at the end of the clause should appear within the ending quotation mark. The correct choice is, "short story, "The Tell-Tale Heart," is quite famous."

This sentence does not contain the right type of quotation marks. Single quotation marks should only appear when a quote appears within another quotation. No other changes are necessary. The correct choice is, "he said, "When love and skill work together, expect a masterpiece." "

This sentence uses the wrong type of quotation marks. Single quotation marks should only be used when the thing being quoted appears within another quotation. Since this is a regular quotation, double quotation marks should be used. The correct choice is, "once said, "Action is the foundational key to all success." "

This sentence contains no errors. The first part of the sentence, "My friend said that," begins an indirect statement, so neither quotation marks nor a comma are necessary because it is not a direct quotation. After the words "Willie Nelson said," however, a direct quotation starts, so a comma is necessary after that "said" and double quotation marks should surround the quote. The correct choice is, "My friend said that Willie Nelson said, "Once you replace negative. "

This sentence misuses quotation marks. What we have is a quotation within another direct quote. Quotation marks should surround both "Confucius...steps" and "When...steps." The difference, however, is that, since "When...steps" is within the quotation "Confucius...steps," single quotation marks should be used for this quote. Note that single quotation marks only appear within another quotation. The correct choice is, " "Confucius said, 'When it is obvious that the goals cannot be reached, don't adjust the goals, adjust the action steps.' " "

This sentence misuses quotation marks. Single quotation marks are only used when a quotation appears within another quotation. In this case, a "special use" of a word, regular quotation marks should be used. The correct choice is, ""study" for tests."

While a colon can be used to introduce a list at the end of an independent clause, the list of three figures is, in this case, a parenthetical aside explaining who the sentence is talking about. As such, it should be set off like other interrupting parenthetical clauses—as in the credited response, which uses em-dashes.
