Which option best replaces the underlined part of the sentence?

Possible Answers:

The menu includes, french fries, milkshakes, and hamburgers. 

The menu includes french fries milkshakes, and hamburgers. 

The menu includes: french fries; milkshakes; and hamburgers. 

The menu includes the following items: french fries; milkshakes; and hamburgers. 

The menu: includes french fries, milkshakes, and hamburgers. 

Correct answer:

The menu includes the following items: french fries; milkshakes; and hamburgers. 

Explanation:

A colon can only follow a grammatically complete, independently valid sentence. The only option that meets this requirement is "The menu includes the following items . . ."

Example Question #2 : Correcting Punctuation Errors: Other Punctuation

Replace the underlined portion with the answer choice that results in a sentence that is clear, precise, and meets the requirements of standard written English. One of the answer choices reproduces the underlined portion as it is written in the sentence.

The plan sought improvements to the city government in three areas municipal finances, emergency services, and traffic enforcement.

Possible Answers:

in three areas, municipal finances emergency services and traffic enforcement.

in three areas municipal finances, emergency services, and enforcing traffic.

in three areas: municipal finances, emergency services, and traffic enforcement.

in three areas municipal finances, emergency services, and traffic enforcement.

in three areas; municipal finances, emergency services, and traffic enforcement.

Correct answer:

in three areas: municipal finances, emergency services, and traffic enforcement.

Explanation:

The sentence is structured so that the list is given as the examples of the "three areas" the sentence mentions. When a list follows a phrase that can be a complete sentence and adds new information to the sentence, a colon should precede the list. Therefore, the correct answer choice is "in three areas: municipal finances, emergency services, and traffic enforcement."

Example Question #171 : Sentence Correction

Replace the underlined portion with the answer choice that results in a sentence that is clear, precise, and meets the requirements of standard written English.

Upon entering the room, you will have two choices either drink from the chalice or drinking from the mug.

Possible Answers:

Upon entering the room, you will have two choices; drinking from the chalice or drink from the mug.

Either drink from the chalice or drinking from the mug, upon entering the room, you will have two choices.

Upon entering the room, you will have two choices either drink from the chalice or drinking from the mug.

Upon entering the room, you will have too choices, either drink from the chalice or drink from the mug.

Upon entering the room, you will have two choices: either drink from the chalice or drink from the mug.

Correct answer:

Upon entering the room, you will have two choices: either drink from the chalice or drink from the mug.

Explanation:

A colon can be used to separate these two clauses. A semi-colon cannot be used, because the second clause cannot stand independently as a full sentence. Both of the verbs used need to be conjugated in the same way. The only answer choice that corrects both of these issues is, "Upon entering the room, you will have two choices: either drink from the chalice or drink from the mug."

Example Question #4 : Correcting Colon Errors

Replace the underlined portion with the answer choice that results in a sentence that is clear, precise, and meets the requirements of standard written English. One of the answer choices repeats the underlined portion as it is written.

The nineteenth-century athlete, C. W. Alcock, was a foundational figure for two separate sports soccer and cricket.

Possible Answers:

two separate sports, soccer, cricket.

two separate sports soccer and cricket.

soccer and cricket: two separate sports.

two separate sports: soccer and cricket.

two separate sports soccer, and cricket.

Correct answer:

two separate sports: soccer and cricket.

Explanation:

The underlined portion includes both a descriptive phrase, "two separate sports," and what it describes, "soccer and cricket." These two phrases need to be separated in a grammatically correct fashion. "Two separate sports: soccer and cricket," is the only answer choice that appropriately separates them,

Example Question #71 : Correcting Punctuation Errors

Replace the underlined portion with the answer choice that results in a sentence that is clear, precise, and meets the requirements of standard written English. One of the answer choices reproduces the underlined portion as it is written in the sentence.

Some laud wind power as a clean, renewable energy source: others worry about the environmental effect of setting up rows of turbines, or “wind farms,” either offshore or on land.

Possible Answers:

Some laud it as a clean, renewable energy source: others worry about the environmental effect of setting up rows of turbines, or “wind farms,” either offshore or on land. 

Some laud it as a clean, renewable energy source, others worry about the environmental effect of setting up rows of turbines, or “wind farms,” either offshore or on land. 

Some laud wind power as a clean, renewable energy source; others worry about the environmental effect of setting up rows of turbines, or “wind farms,” either offshore or on land.

Some laud it as a clean, renewable energy source others worry about the environmental effect of setting up rows of turbines, or “wind farms,” either offshore or on land. 

Some laud it as a clean, renewable energy source: and others worry about the environmental effect of setting up rows of turbines, or “wind farms,” either offshore or on land. 

Correct answer:

Some laud wind power as a clean, renewable energy source; others worry about the environmental effect of setting up rows of turbines, or “wind farms,” either offshore or on land.

Explanation:

The sentence is incorrect as it is written because it is using a colon to combine two independent clauses into a compound sentence. When combining two independent clauses into a compound sentence, one should use either a semicolon or a comma followed by a conjunction. The only answer choice that employs one of these strategies is "Some laud wind power as a clean, renewable energy source; others worry about the environmental effect of setting up rows of turbines, or “wind farms,” either offshore or on land."

Example Question #88 : Punctuation Errors

Replace the underlined portion with the answer choice that results in a sentence that is clear, precise, and meets the requirements of standard written English. One of the answer choices reproduces the underlined portion as it is written in the sentence.

The bride divided her wedding binder into four sections, venue, catering, decorations, and dress.

Possible Answers:

four sections; venue; catering; decorations; and dress.

four sections: venue, catering, decorations, and dress.

four sections; venue, catering, decorations, and dress.

four sections, venue, catering, decorations, and dress.

four sections: venue; catering; decorations; and dress.

Correct answer:

four sections: venue, catering, decorations, and dress.

Explanation:

Because “The bride divided her wedding binder into four sections” is an independent clause (a complete sentence that stands on its own) and because it’s followed by a list, a colon is needed. If the independent clause were followed by another independent clause, a semicolon would be needed. If the beginning of the sentence wasn’t an independent clause, then a colon would not be necessary before the list. Semicolons are only used to separate items in a list if those items contain commas, and since that’s not the case here, we use commas to separate the items in this list.

Example Question #91 : Punctuation Errors

Replace the underlined portion with the answer choice that results in a sentence that is clear, precise, and meets the requirements of standard written English. One of the answer choices reproduces the underlined portion as it is written in the sentence.

I don’t know if I want: the chicken, beef, or vegetarian option for this party, what do you think?

Possible Answers:

I don’t know if I want the chicken, beef, or vegetarian option for this party, what do you think?

I don’t know if I want the chicken, beef, or vegetarian option for this party; what do you think?

I don’t know if I want: the chicken, beef, or vegetarian option for this party, what do you think?

I don’t know if I want the chicken, beef, or vegetarian option for this party: what do you think?

I don’t know if I want: the chicken, beef, or vegetarian option for this party; what do you think?

Correct answer:

I don’t know if I want the chicken, beef, or vegetarian option for this party; what do you think?

Explanation:

Only use a colon to enumerate items in a list if the part of the sentence preceding the list is an independent clause (one that could stand as a complete sentence on its own). Since “I don’t know if I want” isn’t an independent clause, no colon is needed before listing the meal choices. And, since “I don’t know if I want the chicken, beef, or vegetarian option for this party” and “what do you think?” are both independent clauses, they must be separated by a semicolon.

Example Question #7 : Correcting Colon Errors

Replace the underlined portion with the answer choice that results in a sentence that is clear, precise, and meets the requirements of standard written English. One of the answer choices reproduces the underlined portion as it is written in the sentence.

I don’t know what I want, a poodle, a cocker spaniel, or a German shepherd, my sister tells me that each breed has its merits.

Possible Answers:

I don’t know what I want: a poodle, a cocker spaniel, or a German shepherd. My sister tells me that each breed has its merits.

I don’t know what I want; a poodle, a cocker spaniel, or a German shepherd. My sister tells me that each breed has its merits.

I don’t know what I want: a poodle, a cocker spaniel, or a German shepherd, my sister tells me that each breed has its merits.

I don’t know what I want, a poodle, a cocker spaniel, or a German shepherd, my sister tells me that each breed has its merits.

I don’t know what I want; a poodle, a cocker spaniel, or a German shepherd; my sister tells me that each breed has its merits.

Correct answer:

I don’t know what I want: a poodle, a cocker spaniel, or a German shepherd. My sister tells me that each breed has its merits.

Explanation:

Only use a colon to enumerate items in a list if the part of the sentence preceding the list is an independent clause (one that could stand as a complete sentence on its own). Since “I don’t know what I want” is an independent clause, we must use a colon before listing the dog breeds. Because “I don’t know what I want: a poodle, a cocker spaniel, or a German shepherd” and “My sister tells me that each breed has its merits” are both independent clauses, they must be separated by a semicolon or broken into two complete sentences.

Example Question #4 : Correcting Colon Errors

Replace the underlined section with the answer that best results in a sentence that is clear, precise, and meets the requirements of standard written English. 

Have you ever tried: pulpo, padron peppers, or paella? They’re all great examples of classic Spanish cuisine.

Possible Answers:

Have you ever tried pulpo, padron peppers, or paella? They’re all great examples of classic Spanish cuisine.

Have you ever tried pulpo, padron peppers, or paella; they’re all great examples of classic Spanish cuisine?

Have you ever tried pulpo, padron peppers, or paella, they’re all great examples of classic Spanish cuisine?

Have you ever tried, pulpo, padron peppers, or paella? They’re all great examples of classic Spanish cuisine.

Have you ever tried: pulpo, padron peppers, or paella? They’re all great examples of classic Spanish cuisine.

Correct answer:

Have you ever tried pulpo, padron peppers, or paella? They’re all great examples of classic Spanish cuisine.

Explanation:

Because “Have you ever tried” isn’t an independent clause (a complete sentence that can stand on its own), the list that follows it should not be separated with a colon or with any other punctuation. You would only use a colon to introduce the list if the part of the sentence before the list was an independent clause.

Example Question #3 : Correcting Colon Errors

Replace the underlined section with the answer that best results in a sentence that is clear, precise, and meets the requirements of standard written English. 

While I’m away at the convention, I need you to do the following chores: mow the lawn and clean the gutters, which are clogged.

Possible Answers:

While I’m away at the convention, I need you to mow the lawn and clean the gutters, which are clogged.

While I’m away at the convention, I need you to mow the lawn and clean the gutters which are clogged.

While I’m away at the convention, I need you to do the following chores, mow the lawn and clean the gutters, which are clogged.

While I’m away at the convention I need you to do the following chores: mow the lawn and clean the gutters, which are clogged.

While I’m away at the convention, I need you to do the following chores: mow the lawn and clean the gutters, which are clogged.

Correct answer:

While I’m away at the convention, I need you to mow the lawn and clean the gutters, which are clogged.

Explanation:

Because “mow the lawn and clean out the gutters,” isn’t a list of three or more items, no colon is necessary to introduce it. “While I’m away at the convention” and “which are clogged” are dependent clauses, so they must be separated from the main clause with a comma. A better sentence would read as follows: “While I’m away at the convention, I need you to mow the lawn and clean out the gutters, which are clogged.”
