Step-by-step solution for: Commas, Colons, and Semicolons
Here are the correct punctuation marks needed for each sentence, along with where they go and why.
1. At the party there were cake, cookies, punch, and fruit.
* Mark: Commas (`,`)
* Where: After "cake," "cookies," and "punch."
* Why: You need commas to separate items in a list.
2. Our basketball team had too many fouls; we lost the game.
* Mark: Semicolon (`;`)
* Where: After "fouls."
* Why: This connects two complete sentences that are closely related without using a word like "and" or "but."
3. My gym teacher is a strong, healthy man.
* Mark: Comma (`,`)
* Where: After "strong."
* Why: Use a comma between two adjectives ("strong" and "healthy") that describe the same noun ("man").
4. My whole family knew who would win the NBA Championships: the Lakers.
* Mark: Colon (`:`)
* Where: After "Championships."
* Why: A colon is used to introduce an explanation or a specific detail (the name of the team) after a complete thought.
5. He walked all the way to school, but he arrived late.
* Mark: Comma (`,`)
* Where: Before "but."
* Why: Use a comma before a joining word (like "but") when it connects two complete sentences.
6. We wanted to visit three countries in Asia: China, India, and Indonesia.
* Mark: Colon (`:`)
* Where: After "Asia."
* Why: The colon introduces the list of countries mentioned in the first part of the sentence.
7. I saw that my mom was on the phone, so I waited to talk to her.
* Mark: Comma (`,`)
* Where: Before "so."
* Why: Use a comma before a joining word (like "so") when it connects two complete sentences.
8. My teacher said, “If you are unsure about this math problem, please let me know.”
* Mark: Comma (`,`)
* Where: After "said."
* Why: Use a comma to separate the speaker from the quote. (Note: There is also a comma inside the quote after "problem," but the main missing mark usually tested here is the one introducing the quote).
9. You can order different sandwiches at the restaurant: one with bacon and cheese, one with chicken and avocado, or one with ham and provolone.
* Mark: Colon (`:`) and Commas (`,`)
* Where: Colon after "restaurant"; commas after "cheese" and "avocado."
* Why: The colon introduces the list of sandwich options. The commas separate the long descriptions in the list.
10. After our plane landed in Miami, we went to the hotel.
* Mark: Comma (`,`)
* Where: After "Miami."
* Why: When a sentence starts with an introductory phrase telling *when* or *where*, put a comma after it.
11. I ate a lot at lunch; however, I am still hungry.
* Mark: Semicolon (`;`) and Comma (`,`)
* Where: Semicolon after "lunch"; comma after "however."
* Why: Use a semicolon before transition words like "however" when they connect two complete sentences.
12. Last Wednesday, there was a blizzard, and school was canceled.
* Mark: Commas (`,`)
* Where: After "Wednesday" and after "blizzard."
* Why: The first comma follows the introductory time phrase. The second comma goes before "and" because it joins two complete sentences.
13. Let’s go to GameStop; there are new games released today.
* Mark: Semicolon (`;`)
* Where: After "GameStop."
* Why: It connects two related complete sentences without a joining word.

* Mark: Colon (`:`) and Commas (`,`)
* Where: Colon after "I"; commas after "Idaho," "Illinois," and "Indiana."
* Why: The colon introduces the list of states. The commas separate the items in the list.
16. My uncle and aunt live in Conroe, Texas.

* Why: The colon introduces the list of treats. The commas separate the items.
18. My favorite book, *Wonder*, makes me cry.
* Mark: Commas (`,`)
* Where: After "book" and after "*Wonder*."
* Why: The title of the book is extra information. You use two commas to surround extra details inserted in the middle of a sentence.
19. Andre, my brother, has to attend detention after school.
* Mark: Commas (`,`)
* Where: After "Andre" and after "brother."
* Why: "My brother" explains who Andre is. Since it is extra information in the middle of the sentence, it needs commas on both sides.
