1.
In the sentence 'The cake, which was chocolate, was delicious, ' what role does the phrase 'which was chocolate' play?
A) Essential clause.
B) Nonessential clause.
C) Appositive.
D) Direct address.
Show Answer
Explanations:
The phrase "which was chocolate" provides additional information about the cake but is not essential to the sentence's meaning. It can be removed without changing the core message: "The cake was delicious." This makes it a nonessential clause, which requires a comma before and after.
Option Analysis:
Option A:
Essential clause - Incorrect because an essential clause is necessary for the sentence to make sense. Removing this phrase does not affect the main idea.
Option B:
Nonessential clause - Correct, as it provides extra information that can be removed without altering the basic meaning of the sentence.
Option C:
Appositive - Incorrect because an appositive renames or reidentifies a noun. This phrase describes the cake's flavor rather than renaming it.
Option D:
Direct address - Incorrect, as direct address involves speaking to someone directly and is not applicable here.
2.
In the sentence, 'My friend, who is a talented musician, will perform tonight, ' where should the nonessential clause be placed?
A) A.
B) B.
C) At the beginning of the sentence.
D) C.
Show Answer
Explanations:
The nonessential clause "who is a talented musician" provides additional information about the subject but is not essential to the sentence's meaning. According to the rules of comma usage with nonessential clauses, such clauses should be set off by commas. In this case, placing the clause at the beginning of the sentence (Option C) would require surrounding it with commas: "Who is a talented musician, my friend will perform tonight." However, since the original sentence structure places the clause after the subject and before the main verb, Option B correctly identifies where the nonessential clause should be placed without additional punctuation.
Option Analysis:
Option A:
Incorrect as it does not address the placement of the nonessential clause.
Option B:
Correct because the nonessential clause is properly placed after the subject and before the main verb, requiring no additional commas.
Option C:
Incorrect as placing the clause at the beginning would require surrounding it with commas.
Option D:
Incorrect for the same reason as Option C.
3.
Which of the following sentences punctuates the nonessential clause correctly?
A) The book, that I read last night, was fascinating.
B) The book which I read last night was fascinating.
C) The book that I read last night, was fascinating.
D) The book, which I read last night, was fascinating.
Show Answer
Explanations:
Option D correctly uses a comma to set off the nonessential clause "which I read last night." The relative pronoun "which" introduces this additional information that is not essential to the main idea of the sentence, which is that the book was fascinating.
Option Analysis:
Option A:
Incorrect. While a comma is used before "that," it should be "which" for nonessential clauses.
Option B:
Correct in terms of punctuation, but "that" should be "which" for nonessential clauses.
Option C:
Incorrect. The comma after the clause is unnecessary and disrupts the sentence structure.
Option D:
Correct. Uses proper punctuation with a comma before "which" to set off the nonessential clause.
4.

D) B.
Show Answer
Explanations:
The correct answer is
D) B.
The sentence "A. A. D. The book, that I borrowed from the library, is due next week." uses commas to set off a nonessential clause correctly. The relative clause "that I borrowed from the library" provides additional information but is not essential to the meaning of the sentence. Commas are used to separate this nonessential information.
Option Analysis:
Option A:
No sentence provided.

Correct usage of commas for a nonessential clause.

5.
We lived on Oxford Drive which is close to the airport.
A) Essential-no commas needed.
B) Non-essential-add commas around the highlighted part.
C) All the above.
D) None of the above.
Show Answer
Explanations:
The sentence "We lived on Oxford Drive which is close to the airport" contains a nonessential clause, "which is close to the airport," that provides additional information but is not crucial to the main meaning of the sentence. Nonessential clauses should be set off by commas.
Option Analysis:
Option A:
Incorrect because it suggests no commas are needed for a nonessential clause.
Option B:
Correct as it adds the necessary commas to separate the nonessential clause, making the sentence grammatically correct.
Option C:
Incorrect because only one option is correct in this case. Option A and D are incorrect.
Option D:
Incorrect because there is a correct answer among the options provided.
6.
In the sentence, 'My friend, who is a talented musician, will perform tonight, ' where should the nonessential clause be placed?A. Before 'My friend'B. After 'My friend'C. After 'will perform tonight'
A) At the beginning of the sentence.
B) C.
C) A.
D) B.
Show Answer
Explanations:
The nonessential clause "who is a talented musician" provides additional information about the subject "My friend," but it is not essential to the sentence's meaning. According to the rules of comma usage with nonessential clauses, such clauses should be set off by commas and placed either before or after the main clause. In this case, placing the clause after "My friend" (Option B) is correct because it maintains clarity while still providing additional detail.
Option Analysis:
Option A:
Incorrect; placing the nonessential clause at the beginning of the sentence would not be appropriate for a nonessential element.
Option B:
Correct; this placement is standard and maintains proper comma usage.
Option C:
Incorrect; placing the clause after "will perform tonight" would make it essential, which is not the case here.
Option D:
Incorrect; while Option B is correct, this option does not provide a specific placement within the sentence structure.
7.
Choose the sentence that applies commas with nonessential clauses correctly.
A) The book, that I borrowed from the library, is due next week.
B) The book, that I borrowed from the library, is due next week.
C) The book that I borrowed from the library is due next week.
D) A.
Show Answer
Explanations:
Option A and B are identical, making them the same sentence. This sentence includes a nonessential clause "that I borrowed from the library" which provides additional information but is not essential to the meaning of the sentence. Therefore, it should be set off by commas: "The book, that I borrowed from the library, is due next week." However, in standard English grammar, we typically use "which" instead of "that" for nonessential clauses. Thus, the correct form would be: "The book, which I borrowed from the library, is due next week."
Option C omits the commas around the nonessential clause, making it incorrect.
Option D (A) is marked as correct but is actually a duplicate of Option A/B.
Option Analysis:
Option A:
Incorrect; should use "which" and commas.
Option B:
Same as A, incorrect for the same reason.
Option C:
Incorrect; no commas around nonessential clause.
Option D:
Correctly identified but duplicate of A/B.
8.
The scene, loaded with pathos, was beautifully performed.
A) Nonessential appositives.
B) Direct address.
C) Nonessential participial phrase.
D) Conjunctive adverb.
Show Answer
Explanations:
The phrase "loaded with pathos" is a participial phrase that modifies the scene and provides additional descriptive information, but it is not essential to the basic meaning of the sentence. It adds extra detail without changing the core message that the scene was beautifully performed.
Option Analysis:
Option A:
Nonessential appositives are noun phrases that rename or identify a noun and are typically set off by commas, but "loaded with pathos" is not an appositive.
Option B:
Direct address involves speaking directly to someone, which is not present in the sentence.
Option C:
Correct. A nonessential participial phrase like "loaded with pathos" provides additional information but can be set off by commas because it is not essential to the basic meaning of the sentence.
Option D:
Conjunctive adverbs connect independent clauses and are typically used to show transitions, which is not applicable here.
9.
Which of the following sentences uses commas to set off a nonessential clause correctly?A. The book that I borrowed from the library is due next week.B. The book, which I borrowed from the library, is due next week.C. The book which I borrowed from the library is due next week.
A) A.
B) D.
C) The book, that I borrowed from the library, is due next week.
D) B.
Show Answer
Explanations:
The correct usage of commas to set off a nonessential clause is demonstrated in option B: "The book, which I borrowed from the library, is due next week." The relative pronoun "which" introduces a nonessential clause that provides additional information but is not essential to the meaning of the sentence. Therefore, it should be preceded by a comma.
Option Analysis:
Option A:
Incorrect; no commas are needed.
Option B:
Correct; uses commas properly around "which I borrowed from the library."
Option C:
Incorrect; lacks necessary commas, making it a run-on sentence.
Option D:
Incorrect; incorrectly places commas and includes an extra comma before "that."
10.
In the sentence, 'The cake, which was delicious, was baked by my aunt, ' where should the nonessential clause be placed?
A) Before 'was baked by my aunt'.
B) After 'The cake'.
C) Before 'which was delicious'.
D) After 'was delicious'.
Show Answer
Explanations:
The nonessential clause "which was delicious" provides additional information about the cake but is not essential to understanding the main idea that the cake was baked by your aunt. Therefore, it should be placed after 'The cake' with a comma before and after the clause.
Option Analysis:
Option A:
Incorrect. The nonessential clause cannot come before the main clause.
Option B:
Correct. This places the nonessential clause appropriately, maintaining proper sentence structure.
Option C:
Incorrect. Placing it before 'which was delicious' would make it a necessary part of the sentence, which is not the case here.
Option D:
Incorrect. This placement would create an incomplete sentence and disrupt its flow.
11.
What is the purpose of commas in the sentence:My brother, who is a doctor, lives in New York.
A) To separate items in a list.
B) To connect two independent clauses.
C) To set off a nonessential clause.
D) To indicate a pause.
Show Answer
Explanations:
Commas are used to set off a nonessential clause in the sentence "My brother, who is a doctor, lives in New York." The phrase "who is a doctor" provides additional information but is not essential to understanding the main idea that your brother lives in New York. This type of clause can be removed without changing the fundamental meaning of the sentence.
Option Analysis:
Option A:
Incorrect. Commas do not separate items in a list.
Option B:
Incorrect. Commas are not used to connect two independent clauses; that would require a conjunction and a comma, or a semicolon alone.
Option C:
Correct. The commas set off the nonessential clause "who is a doctor."
Option D:
Incorrect. Commas are not used to indicate a pause in this context; they serve to separate additional information.
12.
In the sentence, 'The car, which is parked in the driveway, belongs to my friend, ' where should the nonessential clause be placed?
A) C.
B) B.
C) Before 'belongs to my friend'.
D) A.
Show Answer
Explanations:
The nonessential clause "which is parked in the driveway" provides additional, but not essential, information about the car. According to the rules of comma usage with nonessential clauses, such clauses should be set off by commas. In this sentence, placing the clause before 'belongs to my friend' (Option C) would make it a part of the essential information and thus incorrect.
Option Analysis:
Option A:
Incorrect as it does not address comma usage with nonessential clauses.
Option B:
Correct. The clause "which is parked in the driveway" should be placed after 'belongs to my friend' and set off by commas, making this option correct according to English grammar rules for nonessential clauses.
Option C:
Incorrect as it would make the clause essential information, which is not the case here.
Option D:
Incorrect as it does not address comma usage with nonessential clauses.
13.
The French Revolution, which began in 1789, destroyed the monarchy.
A) A comma connecting two independent clauses.
B) A comma after a dependent clause.
C) Commas surrounding nonessential information.
D) Commas separating items in a list.
Show Answer
Explanations:
The sentence "The French Revolution, which began in 1789, destroyed the monarchy." contains a nonessential clause ("which began in 1789") that provides additional information but is not crucial to the main idea. This type of clause requires commas to set it off from the rest of the sentence.
Option Analysis:
Option A:
Incorrect. The two clauses are connected by a comma, indicating they are independent and could stand alone as separate sentences.
Option B:
Incorrect. There is no dependent clause that requires a comma after it.
Option C:
Correct. A nonessential clause like "which began in 1789" should be set off by commas to indicate it is additional information not essential to the main idea of the sentence.
Option D:
Incorrect. There are no items in a list separated by commas that require analysis here.
14.

A) The artist, who painted this mural is famous.
B) The artist, who painted this mural, is famous.
C) The artist who painted this mural is famous.
D) The artist who painted this mural, is famous.
Show Answer
Explanations:
Option B is correct because it properly uses a comma to set off the nonessential clause "who painted this mural." This clause provides additional information but is not essential to the main idea that "The artist is famous."
Option Analysis:
Option A:
The placement of commas here is incorrect. Commas should be used before and after the nonessential clause for clarity.
Option C:
No comma is needed because the relative clause "who painted this mural" is essential to the meaning of the sentence, identifying which artist is being referred to.
Option D:
The comma placement here is incorrect. A comma should be placed before and after the nonessential clause for clarity.

This clause provides additional information but is not essential to the main idea of the sentence. Therefore, it should be set off with commas.
Option Analysis:
Option A:
Incorrect because no commas are needed for nonessential clauses.
Option B:
Correct as it requires adding commas around the nonessential clause.
Option C:
Incorrect since only one option is correct.

The phrase "who spends a lot of time at the gym" provides additional information but is not essential to the main idea that your neighbor is in excellent shape.
Option Analysis:
Option A:
Incorrect. This rule applies to introductory clauses or phrases, which are typically followed by a comma.
Option B:
Incorrect. This rule pertains to separating items in a series, such as "apples, bananas, and oranges."
Option C:
Correct. The phrase "who spends a lot of time at the gym" is nonessential and should be set off by commas.
Option D:
Incorrect. This rule involves using conjunctions to connect independent clauses with or without commas, which does not apply here.
17.
Choose the sentence that applies commas with nonessential clauses correctly.The dog that is barking, belongs to my neighbor.The dog, that is barking belongs to my neighbor.The dog, which is barking, belongs to my neighbor.
Show Answer
Explanations:
The correct sentence is "The dog, which is barking, belongs to my neighbor." The comma before "which" and the one after it are correctly placed because "which is barking" provides additional information but is not essential to the main clause. This usage of a nonessential relative clause requires commas around the clause.
Option Analysis:
Option A:
Incorrect placement of commas; no comma before or after "that."
Option B:
Incorrect placement of commas; only one comma is needed.
Option C:
Correct usage of commas with a nonessential clause.
Option D:
No comma before or after "that," making it incorrect.
18.
In the sentence, 'My brother, who is a chef, cooked dinner, ' where should the nonessential clause be placed?
A) After 'is a chef'.
B) Before 'who is a chef'.
C) Before 'cooked dinner'.
D) After 'My brother'.
Show Answer
Explanations:
The nonessential clause "who is a chef" provides additional information about the brother but is not essential to the main idea of the sentence, which is that the brother cooked dinner. Nonessential clauses should be set off by commas and can be placed before or after the main clause. However, placing it after "My brother" (Option D) maintains clarity and readability.
Option Analysis:
Option A:
Incorrect. Placing "who is a chef" after "is a chef" would make the sentence confusing as it wouldn't clearly identify who cooked dinner.
Option B:
Incorrect. While this option places the clause before the main verb, it disrupts the natural flow of the sentence and could be seen as less clear.
Option C:
Incorrect. This would place the nonessential clause between two verbs, which is not a standard placement for such clauses.
Option D:
Correct. Placing "who is a chef" after "My brother" keeps the sentence clear and maintains proper punctuation with commas.
19.

B) Non-essential-add commas around the highlighted part.
C) All the above.
D) None of the above.
Show Answer
Explanations:
The phrase "Many Scottish names begin with the prefix 'Mac' which means 'the son of.'" is a non-essential clause providing additional information that can be set off by commas to improve readability but does not change the core meaning. Therefore, adding commas around this part (Option B) is correct.
Option Analysis:
Option A:
Incorrect as it suggests no commas are needed for a non-essential clause.
Option B:
Correct as it properly identifies the need to add commas for clarity in this case.
Option C:
Incorrect since only Option B is correct based on the given context.
Option D:
Incorrect as there is a correct answer among the options provided.
20.
We need a girl who can speak with a Southern accent to play the part.
A) Essential-no commas needed.
B) Non-essential-add commas around the highlighted part.
C) All the above.
D) None of the above.
Show Answer
Explanations:
The sentence "We need a girl who can speak with a Southern accent to play the part" is describing an essential requirement for the role, not additional information that could be set off by commas. Nonessential clauses or phrases are typically introduced by words such as "which," "who," "that," and often contain optional information that does not change the core meaning of the sentence if removed.
Option Analysis:
Option A:
Correct. The requirement is essential, so no commas are needed.
Option B:
Incorrect. Commas would be used to set off nonessential information, which is not present here.
Option C:
Incorrect. Only one option can be correct in this case.
Option D:
Incorrect. The correct answer is among the given options.
21.
Which sentence correctly uses commas with a nonessential clause?
A) The book, which I borrowed from the library, is due tomorrow.
B) The book, that I borrowed from the library, is due tomorrow.
C) The book which I borrowed from the library is due tomorrow.
D) The book that I borrowed from the library is due tomorrow.
Show Answer
Explanations:
The correct answer is A) The book, which I borrowed from the library, is due tomorrow.
In a nonessential clause, commas are used to set off information that is not crucial to the main meaning of the sentence. In option A, "which I borrowed from the library" provides additional but non-essential information about the book and thus requires commas around it.
Option Analysis:
Option A:
Correct use of commas for a nonessential clause.
Option B:
Incorrect; no commas are needed as "that" introduces an essential clause here, not a nonessential one.
Option C:
Incorrect; no commas are used in this case since the relative pronoun "which" is introducing a nonessential clause.
Option D:
Correct grammar but no commas around the nonessential clause, making it incorrect for this question.
22.

A) Essential-no commas needed.
B) Non-essential-add commas around the highlighted part.
C) All the above.
D) None of the above.
Show Answer
Explanations:
The sentence "The store pays the parking fee of any customer who makes a purchase of twenty dollars or more." does not contain a nonessential clause that requires commas. The phrase "who makes a purchase of twenty dollars or more" is essential to the meaning of the sentence, as it specifies the condition under which the store will pay the parking fee.

The nonessential clause "who is a doctor" provides additional information about the subject "My sister," but it is not essential to the sentence's meaning.

Which of the following sentences contains a nonessential clause?
A) The dog which barked loudly was taken to the vet.
B) The dog, which barked loudly, was taken to the vet.
C) The dog that barked loudly, was taken to the vet.
D) The dog that barked loudly was taken to the vet.
Show Answer
Explanations:
Option B is correct because the nonessential clause "which barked loudly" provides additional information about the dog but is not essential to the main idea of the sentence. This clause can be removed without changing the core meaning, making it a nonessential element that should be set off by commas.
Option Analysis:
Option A:
The comma before "which" is unnecessary, as this is an essential relative clause.
Option B:
Correct. Nonessential clause properly set off by commas.
Option C:
The comma after "loudly" is incorrect; it should be a period or no punctuation if using "that." However, since the question focuses on nonessential clauses, this option is not considered correct based on that criterion alone.
Option D:
No commas are needed around the clause "which barked loudly," as it is essential to the sentence's meaning.
Frequently Asked Questions
What are nonessential clauses, and why do we use commas with them?
Nonessential clauses provide additional information that is not crucial to the main meaning of a sentence. Commas are used to set off these clauses, making the sentence easier to read and understand without changing its essential meaning.
Can you give an example of how commas with nonessential clauses work in a sentence?
Sure, consider the sentence "The dog, which is brown and fluffy, likes to play fetch." The clause "which is brown and fluffy" provides extra information about the dog but is not essential. Commas are used before and after this clause to separate it from the main part of the sentence.
How do nonessential clauses differ from essential clauses in terms of punctuation?
Nonessential clauses are set off by commas, whereas essential clauses, which are necessary for the sentence to make sense, are not separated by commas. For example, "The dog that barked loudly scared the neighbors" uses no commas because the clause "that barked loudly" is essential.
Are there any exceptions to using commas with nonessential clauses?
Yes, sometimes commas are not used even for nonessential clauses if the clause is very short or closely tied to a noun. For instance, in "The book on the shelf, which I bought yesterday, is missing," the comma after "shelf" is optional because the clause is relatively brief and directly related to the noun.
Why are nonessential clauses important in writing?
Nonessential clauses add detail and context, making writing more vivid and informative. They help convey additional information without disrupting the flow of the sentence, allowing for a smoother reading experience.
