Show Answer Key & Explanations Step-by-step solution for: Punctuation - Semi-colons. Using Semi-colons to Link Ideas
Here is the corrected version of each sentence with appropriate punctuation (semicolons, colons, dashes, quotation marks, italics/underlines, and parentheses) added where needed. I'll explain the changes after the corrections.

---

Corrected Sentences:

1. The men in question—Harold Keene, Jim Peterson, and Gerald Greene—deserve awards.
*Explanation:* Dashes are used to set off a parenthetical list that adds clarification.

2. Several countries participated in the airlift: Italy, Belgium, France, and Luxembourg.
*Explanation:* A colon introduces a list that explains or follows from the preceding clause.

3. Only one course was open to us: surrender, said the ex-major, and we did.
*Explanation:* A colon introduces the explanation ("surrender"). Quotation marks aren't needed because the speaker's words are not directly quoted; instead, the phrase "said the ex-major" is an interrupting clause. However, if we interpret this as a direct quote, it would be better written as:
Revised: Only one course was open to us: surrender, the ex-major said, and we did.
*(Note: This version uses a comma for the interrupting clause.)*

4. Judge Carswell, later to be nominated for the Supreme Court, had ruled against civil rights.
*Explanation:* Parentheses or commas can be used for nonessential information. Here, commas are sufficient to set off the additional detail about Judge Carswell.

5. In last week’s *New Yorker*, one of my favorite magazines, I enjoyed reading Leland’s article “How Not to Go Camping.”
*Explanation:* Italicize magazine titles (*New Yorker*), use quotation marks for article titles (“How Not to Go Camping”), and add commas around the appositive phrase.

6. “Yes,” Jim said, “I’ll be home by ten.”
*Explanation:* Direct speech requires quotation marks. Use commas to separate the dialogue from the speaker tag.

7. There was only one thing to do: study till dawn.
*Explanation:* A colon introduces the specific action that follows.

8. Montaigne wrote the following: “A wise man never loses anything, if he has himself.”
*Explanation:* A colon introduces the quote. Quotation marks enclose the direct quote.

9. The following are the primary colors: red, blue, and yellow.
*Explanation:* A colon introduces the list of colors.

10. Arriving on the 8:10 plane were Liz Brooks, my old roommate, her husband, and Tim, their son.
*Explanation:* Add a colon after “8:10” for time notation. Use commas to separate items in a compound list and clarify relationships.

11. When the teacher commented that her spelling was poor, Lynn replied, “All the members of my family are poor spellers. Why not me?”
*Explanation:* Use quotation marks for direct speech. Comma before the quote to separate it from the speaker tag. Capitalize the first word inside the quotation.

12. He used the phrase “you know” so often that I finally said, “No, I don’t know.”
*Explanation:* Place quotation marks around the repeated phrase “you know” and the response. Use a comma after “said.”

13. The automobile dealer handled three makes of cars: Volkswagens, Porsches, and Mercedes-Benz.
*Explanation:* A colon introduces the list of car brands. Note: “Mercedes-Benz” is hyphenated.

14. Though Phil said he would arrive on the 9:19 flight, he came instead on the 10:36 flight.
*Explanation:* Use colons in time notation (9:19, 10:36). No other punctuation needed.

15. Whoever thought, said Helen, that Jack would be elected class president?
*Explanation:* This is a question with a speaker interruption. Rewrite for clarity:
Better: “Whoever thought that Jack would be elected class president?” said Helen.
Or: “Whoever thought that Jack would be elected class president?” Helen asked.
But if keeping original structure:
Revised: “Whoever thought that Jack would be elected class president?” said Helen.
*(Direct question with quotation marks and proper speaker tag.)*

16. In baseball, a show boat is a man who shows off.
*Explanation:* This sentence is correct as is. "Show boat" is a metaphorical term; no special punctuation needed unless it's being defined. If emphasizing the term:
Alternative: In baseball, a *show boat* is a man who shows off.
*(Italics for emphasis or definition.)*

17. The minister quoted Isaiah 5:21 in last Sunday’s sermon.
*Explanation:* Use a colon in biblical references (Isaiah 5:21).

18. There was a very interesting article entitled “The New Rage for Folk Singing” in last Sunday’s *New York Times* newspaper.
*Explanation:* Use quotation marks for article titles and italics for the newspaper name.

19. Whoever is elected secretary of the club—Ashley, or Chandra, or Aisha—must be prepared to do a great deal of work, said Jumita, the previous secretary.
*Explanation:* Use dashes to set off the list of possible candidates. Alternatively, commas could be used, but dashes emphasize the list. Also, use a comma after “work” to separate the main clause from the speaker tag.

20. Darwin’s *On the Origin of Species* (1859) caused a great controversy when it appeared.
*Explanation:* Italicize book titles (*On the Origin of Species*). Use parentheses for the publication year.
