Step-by-step solution for: Commas, Colons, and Semicolons, Free PDF Download - Learn Bright
Let's solve each sentence by identifying the missing punctuation mark (comma, colon, or semicolon), where it should go, and why it is needed.
---
- Missing: Comma
- Where: After "cake", "cookies", "punch"
- Why: This is a list of items. Commas separate items in a series.
- Corrected: *At the party there were cake, cookies, punch, and fruit.*
---
- Missing: Semicolon or period
- Where: Between "fouls" and "we"
- Why: Two independent clauses joined without proper punctuation. A semicolon can join two closely related independent clauses.
- Corrected: *Our basketball team had too many fouls; we lost the game.*
*(Alternatively: "Our basketball team had too many fouls. We lost the game." with a period)*
---
- Missing: Comma
- Where: Between "strong" and "healthy"
- Why: Two adjectives modifying the same noun ("man") that are coordinate adjectives (can be reversed or joined with "and").
- Corrected: *My gym teacher is a strong, healthy man.*
---
- Missing: Colon
- Where: After "Championships"
- Why: The second part explains or lists what the first part refers to — a definition or explanation.
- Corrected: *My whole family knew who would win the NBA Championships: the Lakers.*
---
- Missing: Comma
- Where: Before "but"
- Why: A coordinating conjunction ("but") joins two independent clauses. A comma is needed before it.
- Corrected: *He walked all the way to school, but he arrived late.*
---
- Missing: Comma
- Where: After "Asia", after "China", after "India"
- Why: List of countries; needs commas between items. Also, "in Asia" is followed by a list, so a comma after "Asia" helps separate the prepositional phrase from the list.
- Corrected: *We wanted to visit three countries in Asia: China, India, and Indonesia.*
*(Note: Colon may also be appropriate here for clarity. But if only comma/semicolon/colon allowed, colon is best.)*
---
- Missing: Comma
- Where: Before "so"
- Why: Two independent clauses joined by a coordinating conjunction ("so").
- Corrected: *I saw that my mom was on the phone, so I waited to talk to her.*
---
- Missing: Comma
- Where: After "problem"
- Why: In direct quotation, a comma separates the introductory clause from the quote.
- Corrected: *My teacher said, “If you are unsure about this math problem, please let me know.”*
*(Also needs comma inside quote after "problem")*
---
- Missing: Colons and commas
- Where: After "restaurant", between sandwich descriptions
- Why: The sentence introduces a list of options. Use a colon after "restaurant". Then use commas to separate the items.
- Corrected: *You can order different sandwiches at the restaurant: one with bacon and cheese, one with chicken and avocado, or one with ham and provolone.*
---
- Missing: Comma
- Where: After "Miami"
- Why: A dependent clause ("After our plane landed in Miami") is followed by an independent clause. A comma is needed to separate them.
- Corrected: *After our plane landed in Miami, we went to the hotel.*
---
- Missing: Comma
- Where: After "lunch" and before "however"
- Why: "However" is a conjunctive adverb used to connect two ideas. It requires a comma before and after when used mid-sentence.
- Corrected: *I ate a lot at lunch; however, I am still hungry.*
*(Semicolon before "however" is acceptable, or use a period: "I ate a lot at lunch. However, I am still hungry.")*
---
- Missing: Comma
- Where: After "blizzard"
- Why: Two independent clauses joined by "and" — need a comma before the conjunction.
- Corrected: *Last Wednesday there was a blizzard, and school was canceled.*
---
- Missing: Semicolon or period
- Where: Between "GameStop" and "there"
- Why: Two independent clauses. A semicolon can link them if they're closely related.
- Corrected: *Let’s go to GameStop; there are new games released today.*
*(Or: "Let’s go to GameStop. There are new games released today.")*
---
- Missing: Comma
- Where: After "15"
- Why: Dates require a comma between day and year.
- Corrected: *My little cousin was born on August 15, 2018.*
---
- Missing: Colon
- Where: After "I"
- Why: Introduces a list of states.
- Corrected: *There are four states that start with the letter I: Idaho, Illinois, Indiana, and Iowa.*
---
- Missing: Comma
- Where: After "Conroe"
- Why: City and state names require a comma between them.
- Corrected: *My uncle and aunt live in Conroe, Texas.*
---
- Missing: Colon and commas
- Where: After "party", after each item except last
- Why: Introduces a list of treats. Use colon after "party". Then use commas in the list.
- Corrected: *I bought a lot of treats for the party: ice cream, cookies, cake, candy, and chocolate.*
---
- Missing: Quotation marks or italics (not punctuation listed)
- But: If only comma, colon, semicolon allowed — no correction needed unless considering title formatting.
- Wait: "Wonder" is a book title — should be italicized or in quotes. But since only comma, colon, semicolon are options, perhaps no punctuation needed.
- Conclusion: No punctuation error using only the three given marks.
- Answer: No punctuation needed from the three options.
---
- Missing: Comma
- Where: After "Andre"
- Why: Appositive — "my brother" identifies "Andre". Needs comma around it.
- Corrected: *Andre, my brother, has to attend detention after school.*
---
- Missing: Comma
- Where: After "school"
- Why: Dependent clause ("When I am in high school") followed by independent clause. Need comma.
- Also: List of clubs — need commas between items.
- Corrected: *When I am in high school, I want to join the wrestling, basketball, drama club, and chess club.*
