A) Tuesday,.
B) Since,.
C) Work,.
D) Absent,.
Show Answer

Option Analysis:
Option A:
Correct. Comma goes after "Tuesday".
Option B:
Incorrect. The conjunction "Since" does not require a comma before it.
Option C:
Incorrect. No comma is needed after "Work" in this context.
Option D:

No comma needed as this is not a quoted speech followed by attribution.
Option C:
No comma required for introductory phrases or clauses that are not direct quotations.

4.
Identify each group of words:Kevin Durant is a good basketball player, LBJ is bad at basketball.
A) Fragment.
B) Run-on.
C) Sentence.
D) Comma Splice.
Show Answer
Explanations:
A comma splice occurs when two independent clauses are joined by a comma instead of appropriate punctuation such as a semicolon or conjunction. In the given example, "Kevin Durant is a good basketball player" and "LBJ is bad at basketball" are both independent clauses that could be correctly connected with a semicolon: "Kevin Durant is a good basketball player; LBJ is bad at basketball." Alternatively, they can be joined by a coordinating conjunction like "but": "Kevin Durant is a good basketball player, but LBJ is bad at basketball."
Option Analysis:
Option A:
Fragment: Neither sentence is incomplete or lacks a subject and verb.
Option B:
Run-on: This term describes sentences that lack appropriate punctuation between independent clauses, which fits the given example.
Option C:
Sentence: Both provided statements are complete thoughts with subjects and verbs.
Option D:
Comma Splice: Correct. Two independent clauses joined by a comma without additional punctuation or conjunction.
5.
When should a comma be used when directly addressing a person?
A) Between the name of the person being addressed and the content of the message.
B) Between the subject and verb in a sentence.
C) Between two independent clauses joined by a coordinating conjunction.
D) Before and after a transitional term or non-essential information.
Show Answer
Explanations:
Commas are used to separate the name of the person being addressed from the content of the message when directly addressing a person. This is known as an appositive phrase and requires a comma before and after the name if it is set off by "Mr.", "Mrs.", "Ms.", etc., or if it's not essential information.
Option Analysis:
Option A:
Correct. Commas are used between the name of the person being addressed and the content of the message.
Option B:
Incorrect. Commas are not typically used to separate the subject and verb in a sentence unless it is part of a list or for other specific reasons like interrupting dialogue.
Option C:
Incorrect. Commas are used between independent clauses joined by coordinating conjunctions, but this does not apply to directly addressing someone.
Option D:
Incorrect. Commas are used before and after a transitional term or non-essential information, not for directly addressing someone.
6.
Where should the comma be placed? I attend school in Neosho Missouri.
A) Neosho,.
B) In,.
C) I,.
D) School,.
Show Answer
Explanations:
The correct placement of the comma in this sentence is after "Neosho" because it separates the city from the state, which are two distinct pieces of geographical information. This usage of a comma helps to clarify that Neosho is a specific location within Missouri.
Option Analysis:
Option A:
Correct. Comma properly placed after "Neosho" to separate city and state.
Option B:
Incorrect. Placing the comma before "In" would be redundant and grammatically incorrect.
Option C:
Incorrect. Starting with a comma is not appropriate here as it's the beginning of the sentence.
Option D:
Incorrect. A comma after "School" does not make sense in this context.
7.
Mark searched the nearly empty refrigerator for a midnight snack his only choices were curdled milk, stale pizza, and grape jelly.
A) Snack, but his.
B) Snack, his.
C) Snack, so his.
D) No change needed.
Show Answer
Explanations:
The correct answer is Option A: "Snack, but his." This option correctly uses a comma to separate two independent clauses and indicates a contrast between the actions of searching for a snack and the reality of what was available. The phrase "but his" suggests that despite looking for something better, Mark's only options were not ideal.
Option Analysis:
Option A:
Correct usage of comma to separate independent clauses indicating contrast.
Option B:
Incorrect; no comma is needed here as it does not separate two independent clauses.
Option C:
Incorrect; "so" would imply a result, which is not the intended meaning in this sentence.
Option D:
Incorrect; the sentence requires a comma to properly structure the ideas presented.
8.
When should a comma be used after an introductory word, phrase, or clause?
A) When joining two independent clauses.
B) When the subject of the sentence is placed at the end.
C) When beginning a sentence with an introductory word, phrase, or clause.
D) When directly addressing a person.
Show Answer
Explanations:
Commas are used after an introductory word, phrase, or clause to ensure clarity and proper separation of ideas in a sentence. This rule applies when the introductory element is at the beginning of the sentence, making option C correct.
Option Analysis:
Option A:
Commas are not typically used to join two independent clauses; instead, a conjunction (such as "and," "but," etc.) or a semicolon would be appropriate.
Option B:
When the subject of the sentence is placed at the end, no comma is needed before it unless there's an introductory element that requires separation.
Option C:
Correct. Commas are used after an introductory word, phrase, or clause to separate them from the main part of the sentence for clarity.
Option D:
While commas can be used when directly addressing a person (e.g., "Hey there!"), this is not a universal rule and depends on context. It's more about introductory elements at the beginning of sentences.
9.
Which of the following sentences is a comma splice?
A) I love pizza, it's my favorite food.
B) She went to the store, and bought some bread.
C) He is tired, so he went to bed early.
D) The cat is sleeping, and the dog is barking.
Show Answer
Explanations:
A comma splice occurs when two independent clauses are joined by a comma instead of a conjunction, semicolon, or period. In Option A, "I love pizza" and "it's my favorite food" are both independent clauses that could stand as separate sentences but are incorrectly joined with just a comma.
Option Analysis:
Option A:
Incorrect - Comma splice.
Option B:
Correct - Proper use of conjunction "and".
Option C:
Correct - Proper use of conjunction "so" and comma before it.
Option D:
Correct - Proper use of conjunction "and".
10.
The clowns were scary, the jester was funny.
A) Run-on.
B) Fragment.
C) Sentence.
D) Comma Splice.
Show Answer
Explanations:
A comma splice occurs when two independent clauses are joined by a comma instead of being properly connected with appropriate punctuation, such as a semicolon or conjunction. In the given sentence, "The clowns were scary" and "the jester was funny" are both independent clauses that could stand alone as separate sentences. However, they are incorrectly joined by a period to form two complete sentences.
Option Analysis:
Option A:
Run-on refers to a sentence that is too long or complex and lacks proper punctuation for clarity.
Option B:
Fragment means a sentence that is incomplete and does not express a full thought.
Option C:
Sentence is the correct grammatical structure, but it does not apply here as there are issues with how the sentences are joined.
Option D:
Correct. Comma splice because two independent clauses are incorrectly joined by a comma or in this case, no punctuation at all.
11.

A) The cake was delicious, everyone enjoyed it.
B) I will call you tomorrow, after I finish work.
C) She is a talented musician, and she plays the piano beautifully.
D) The weather is nice, let's go for a walk.
Show Answer
Explanations:

Option Analysis:
Option A:
No comma error.
Option B:
Correct use of a comma to separate two independent clauses joined by "after."
Option C:
Correct use of a comma to separate an introductory element and the main clause.
Option D:
Comma should be placed before "let's" to separate the two independent clauses: "The weather is nice, let's go for a walk."
12.
Which of the following sentences contains a comma splice?
A) I like to swim, it's very relaxing.
B) She went to the store, and bought some bread.
C) He is tired, so he went to bed early.
D) The cat is sleeping, and the dog is barking.
Show Answer
Explanations:
A comma splice occurs when two independent clauses are joined by a comma instead of appropriate punctuation, such as a semicolon or conjunction with a coordinating conjunction (and, but, for, nor, so, yet).
Option Analysis:
Option A:
This sentence contains a comma splice because "I like to swim" and "it's very relaxing" are two independent clauses joined by a comma. It should be corrected to: "I like to swim; it's very relaxing." or "I like to swim, and it's very relaxing."
Option B:
This sentence is correctly punctuated with an appropriate conjunction ("and").
Option C:
This sentence uses a comma followed by the coordinating conjunction "so," which is correct.
Option D:
This sentence also uses a comma followed by the coordinating conjunction "and," which is correct.
13.
Correct the comma usage in sentence or indicate that the comma was used correctly. Peekskill NY, 10566
A) Peekskill, NY 10566.
B) Peekskill, NY, 10566.
C) No Comma error.
D) Peekskill NY 10566,.
Show Answer
Explanations:
The correct answer is Option A: Peekskill, NY 10566. In this case, a comma is used to separate the city and state in an address format that does not include a zip code as part of the state designation. The claimed correct answer omits the unnecessary second comma after "NY," which would be appropriate if the postal code were included immediately following.
Option Analysis:
Option A:
Correct usage; no additional commas needed.
Option B:
Incorrect; the second comma is unnecessary and creates a redundancy in the address format.
Option C:
Incorrect; there is indeed a comma error that needs correction.
Option D:
Incorrect; this option incorrectly adds a period at the end, which is not part of standard address formatting.
14.
What punctuation should end the following sentence?Your choices for breakfast are scrambled eggs, pancakes, or cereal
A) Period.
B) Question mark.
C) Exclamation point.
D) None of the above.
Show Answer
Explanations:
The sentence "Your choices for breakfast are scrambled eggs, pancakes, or cereal" is a statement providing information about available options. Statements in English typically end with a period to indicate the completion of an idea.
Option Analysis:
Option A:
Correct. The sentence is a statement and should end with a period.
Option B:
Incorrect. This would be used for questions, which this sentence is not.
Option C:
Incorrect. This is used to express strong emotion or emphasis, neither of which apply here.

15.

A) No comma error.
B) Darla bit into the hot gooey, bread.
C) Darla bit into the hot, gooey, bread.
D) Darla bit into the hot gooey bread.
Show Answer
Explanations:
The sentence "Darla bit into the hot, gooey bread" is correctly punctuated. The comma between "hot" and "gooey" is used to separate two adjectives that both modify "bread." This usage is correct according to the rule that when two or more adjectives are used to describe a noun and they could be separated by "and," a comma should be placed before the last adjective.
Option Analysis:
Option A:
No comma error. (Correct)
Option B:
Incorrect; it adds an unnecessary comma after "gooey."
Option C:
Incorrect; it adds a redundant comma between adjectives modifying the same noun.
Option D:
Incorrect; it omits necessary commas, making the sentence grammatically incorrect.
16.

B) Jen isn't very funny, but her best friend Pam is hilarious.
C) Jen isn't very funny but her best friend, Pam is hilarious.

Show Answer
Explanations:
Option B is correct because it properly uses a comma to separate two independent clauses joined by the conjunction "but." The sentence structure requires a comma before "but" to ensure clarity and proper punctuation.
Option Analysis:
Option A:
Incorrect. No comma is needed between the two independent clauses.
Option B:
Correct. Proper use of a comma before "but."
Option C:
Incorrect. The comma after "Pam" is unnecessary and disrupts the sentence structure.

A) Yes.
B) No.

Option A:
No comma error. Incorrect as it omits the necessary comma to separate the two independent clauses.
Option B:
I think I have a fever, so I want to go home. Correct usage of comma before "so."
Option C:
I think I have a fever so, I want to go home. Incorrect as it places the comma after "so," which is not required.

Show Answer
Explanations:
The correct answer is

This sentence does not require a comma before any coordinating conjunction because it consists of a single independent clause and no dependent clauses or elements that would necessitate a comma for separation.
Option Analysis:
Option A:
No comma needed as there is only one independent clause.
Option B:
Incorrect. "However" should be preceded by a comma when it starts a sentence, but in this case, it's not the beginning of the sentence and no comma is required before it.
Option C:
Incorrect. The coordinating conjunction "but" connects two independent clauses without requiring a comma as there are no other elements that would necessitate one.

20.
What is the error in this sentence:'I went to the park, I saw a duck.'
A) Comma splice.
B) Run-on sentence.
C) No error.
D) Sentence fragment.
Show Answer
Explanations:
The sentence "I went to the park, I saw a duck." contains a comma splice. A comma splice occurs when two independent clauses are joined by a comma instead of being properly connected with appropriate punctuation (such as a semicolon) or a conjunction.
Option Analysis:
Option A:
Correct. The sentence uses a comma to join two independent clauses, which is a comma splice.
Option B:
Incorrect. While the sentence does have two independent clauses, it is not a run-on sentence because there is punctuation between them (albeit incorrect).
Option C:
Incorrect. The sentence has an error related to proper punctuation of independent clauses.
Option D:
Incorrect. The sentence does not consist of a single clause, so it cannot be classified as a sentence fragment.
21.
Which of the following words would BEST complete the sentence:If you want to REALLY know me, just take a sneak peek ..... my journals.
A) For.
B) Around.
C) Beside.
D) Into.
Show Answer
Explanations:
The word "Into" is the best choice to complete the sentence because it implies a deeper, more intimate exploration of the journals, which aligns with the idea of wanting someone to really know you by delving into your personal writings. "For," "Around," and "Beside" do not convey this sense of penetration or deep understanding.
Option Analysis:
Option A:
For - This preposition does not fit the context well as it suggests a purpose rather than an action of looking inside.
Option B:
Around - This implies circling around or surrounding, which is too superficial for the intended meaning.
Option C:
Beside - This means next to or alongside, not indicating any form of exploration or insight.
Option D:
Into - This correctly suggests a deep look inside, fitting the context perfectly.
22.
Which of the following sentences correctly uses a comma to set off non-essential information?
A) I will unfortunately not be able to attend graduation this year.
B) International Students, who come from all over the world, often live close to the college.
C) The GED test has 5 sections; furthermore, the writing test has 2 parts.
D) Paco told his parents, 'I've just signed up for a Yoga course at Edmonds CC!'.
Show Answer
Explanations:
Option B correctly uses a comma to set off non-essential information: "who come from all over the world" is additional, non-essential information about International Students that can be removed without changing the core meaning of the sentence. The comma before "who" properly sets this phrase apart.
Option Analysis:
Option A:
No non-essential information to set off with a comma.
Option B:
Correct use of commas for non-essential information.
Option C:
Semicolons are used instead, not commas. "Furthermore" is a coordinating conjunction that does not require a comma in this context.
Option D:
Commas are correctly used to separate the dialogue tags but do not set off non-essential information within the sentence itself.
23.
Where should the comma go in this sentence? 'In the morning I like to drink coffee.'
A) In, the morning.
B) The sentence does not need a comma.
C) In, the morning,.
D) In the morning,.
Show Answer
Explanations:
The sentence "In the morning I like to drink coffee." does not require a comma because it is a simple statement without any clauses that would necessitate punctuation for clarity. Commas are used in English to separate elements within a list, introduce or interrupt direct speech, set off non-essential information, and manage complex sentences with multiple clauses.
Option Analysis:
Option A:
Incorrect. The prepositional phrase "In the morning" is essential to the meaning of the sentence and does not require a comma.
Option B:
Correct. The sentence does not need any commas for proper grammar and clarity.
Option C:
Incorrect. Adding a comma after "morning" would create an unnecessary pause in the sentence, making it grammatically incorrect.
Option D:
Incorrect. While "In the morning," could be used to introduce a dependent clause (e.g., "In the morning, I like to drink coffee before starting work"), this is not necessary for the given independent clause.
24.
I marked the passage with a purple flag, that weekend I investigated it further.
A) Fragment.
B) Comma Splice.
C) Sentence.
D) Run-on.
Show Answer
Explanations:
A comma splice occurs when two independent clauses are joined by a comma instead of appropriate punctuation such as a semicolon, period, or conjunction. In the given sentence, "I marked the passage with a purple flag" and "that weekend I investigated it further" are both independent clauses that could stand alone as sentences. Joining them with only a comma creates a comma splice.
Option Analysis:
Option A:
Fragment - This is incorrect because each part of the sentence can be a complete thought.
Option B:
Comma Splice - This is correct as explained above.
Option C:
Sentence - While technically this is a complete sentence, it's not the specific error being identified here.
Option D:
Run-on - A run-on typically involves joining independent clauses without any punctuation or conjunctions, which isn't the case here as there is a comma present.
25.
I went to Italy last year, it was a great trip.
A) Comma splice.
B) Sentence fragment.
C) No error.
D) Run-on sentence.
Show Answer
Explanations:
A comma splice occurs when two independent clauses are joined by a comma instead of appropriate punctuation such as a semicolon, conjunction with a coordinating conjunction (and, but, for, nor, yet, so), or a period. In the given sentence "I went to Italy last year, it was a great trip," there is no proper punctuation between the two independent clauses.
Option Analysis:
Option A:
Correct. The sentence demonstrates a comma splice.
Option B:
Incorrect. The sentence does not form a fragment.
Option C:
Incorrect. There is an error in the sentence structure.
Option D:
Incorrect. The sentence is not a run-on sentence due to missing appropriate punctuation between clauses.
26.
How many commas are needed in this sentence? 'The conference was attended by scientists engineers doctors and teachers.'
Show Answer
Explanations:
The sentence 'The conference was attended by scientists, engineers, doctors, and teachers.' requires three commas to separate the items in a list of four professions. Commas are used to create a series of elements that are non-essential to the main clause.
Option Analysis:
Option A:
Incorrect. Only one comma is not sufficient for separating multiple items in a list.
Option B:
Incorrect. Four commas would be needed if 'and' were replaced with another conjunction, but here it's used to separate the last item in the series.
Option C:
Correct. Three commas are necessary for proper punctuation of a list within a sentence.
Option D:
Incorrect. Two commas would not be enough to properly separate all items in the list.
27.
How many commas should be added to this sentence? I need to stop by the store to pick up tortillas grated cheese tomatoes ground beef and jalapenos.
Show Answer
Explanations:
The sentence requires four commas to separate the items in a list according to the Oxford comma rule, which is commonly used in English writing for clarity and readability. The items are "tortillas," "grated cheese," "tomatoes," "ground beef," and "jalapenos."
Option Analysis:
Option A:
Incorrect. Only one comma would separate the first two items, not enough to list all five.
Option B:
Incorrect. Three commas are insufficient as they do not fully separate each item in the list.
Option C:
Incorrect. Six commas are too many; only five items need separation.
Option D:
Correct. Four commas properly separate the five items in the list, adhering to the Oxford comma rule.
28.
Correct the comma usage in sentence or indicate that the comma was used correctly. "My little sister, won the whole tournament" , Jackie said.
A) "My little sister won the whole tournament" Jackie, said.
B) " My little sister won the whole tournament, " Jackie said.
C) "My little sister won the whole tournament" , Jackie said.
D) No comma error.
Show Answer
Explanations:
The correct answer is
B) " My little sister won the whole tournament, " Jackie said.
This option uses a comma to separate the introductory phrase from the main clause and places the closing quotation mark before the attribution tag ("Jackie said"). The comma here is necessary because it indicates a pause in speech or writing that separates additional information (the description of the sister) from the direct statement.
Option Analysis:
Option A:
Incorrect. It removes the needed comma, making the sentence structure unclear.
Option B:
Correct. Uses a comma to separate the introductory phrase and places quotation marks correctly.
Option C:
Incorrect. Places an unnecessary comma after "tournament," which is not required in this context.
Option D:
Incorrect. Indicates no comma error, but there is one in the original sentence.

B) After the rock show the musicians headed to the diner, for snacks.
C) After the rock show the musicians headed to the diner for snacks.
D) No comma error.
Show Answer
Explanations:
The sentence "After the rock show, the musicians headed to the diner for snacks." is correctly punctuated. The comma after "rock show" separates the introductory element from the main clause and improves readability without altering the meaning of the sentence.
Option Analysis:
Option A:
Incorrect. Commas are not needed between "After" and "the rock show."
Option B:
Incorrect. The comma after "diner" is unnecessary, as it does not introduce a non-essential clause or phrase.

Correct. No comma error in the sentence.
30.
Identify the sentence with the correct use of commas.
A) My brother, who is a great cook made dinner for us.
B) My brother who is a great cook made dinner for us.
C) My brother who is a great cook, made dinner for us.
D) My brother, who is a great cook, made dinner for us.
Show Answer
Explanations:
The correct use of commas in this sentence is to set off the non-essential clause "who is a great cook." This clause provides additional information but is not essential to the meaning of the sentence, hence it should be separated by commas. Option D correctly uses these commas.
Option Analysis:
Option A:
Commas are incorrectly placed; they should separate the non-essential clause.
Option B:
No commas are used, which is incorrect for a non-essential clause.
Option C:
The comma after "brother" is misplaced and unnecessary.
Option D:
Correct use of commas to set off the non-essential clause.
