Example Question #1 : Identifying Punctuation Errors: Commas In Lists
Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.
Carlos, Jim, and their sister, decided not to visit the old shack by the beach; instead, they stayed home and shared ghost stories in the dark. No error
beach; instead,
in the dark
No error
shared ghost stories
sister, decided
sister, decided
A comma should never end a list: "Carlos, Jim, and their sister decided . . ."
Example Question #1 : Identifying Punctuation Errors: Commas In Lists
Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.
Sarah wanted to arrive at the store in time to buy the fresh bread cereal, and chocolate sauce. No error
fresh bread
No error
in time
Sarah
to arrive
fresh bread
Without a comma to make the "fresh bread" an item on the list, the item is unclear: is "fresh bread cereal" an item, or "fresh bread?" We need a comma to clarify.
Example Question #1 : Identifying Punctuation Errors: Commas In Lists
Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.
Bill, Jane and Jared went to the movies every Sunday afternoon; they liked to sit at the back of the movie theatre because it offered the best view. No error
Bill, Jane and Jared
No error
it offered
afternoon; they
every
Bill, Jane and Jared
The phrase “Bill, Jane and Jared” should be “Bill, Jane, and Jarred” because the friend’s names are presented as a list. Words, clauses, or phrases in a series should always be separated by a comma. The sentence “Bill and Jane went to the movies” does not require a comma, but adding the third name, Jared, requires a comma between the three names. Be sure to note that there is no comma after the last word or phrase in the sequence.
Example Question #2 : Identifying Punctuation Errors: Commas In Lists
Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.
Mr. Williams has a number of diverse interests, including skateboarding, and playing video games. No error
interests, including
a number
No error
playing
skateboarding, and
skateboarding, and
There should not be a comma between the words “skateboarding” and “and.” In other words, the second part of the sentence should read “including skateboarding and playing video games.” This is because there are only two interests listed. A comma should only be used in lists containing three or more items.
Example Question #3 : Identifying Punctuation Errors: Commas In Lists
Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.
By the end of the night, Derrick could tell that all the guests were full, happy and tired; the party had truly been a success. No error
happy and
night, Derrick
been
tired; the
No error
happy and
Since the list "full, happy, and tired" has more than 2 items, each item before the last item must be separated using a comma. Inserting a comma after "happy" will make this sentence correct, so the underlined phrase "happy and" must be changed. Note that a semicolon is correctly used to separate two independent clauses from one another in this sentence.
Example Question #4 : Identifying Punctuation Errors: Commas In Lists
Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.
Yolanda, Sam are going to college in the fall, and they are nervous about living away from home. No error
are
fall, and
No error
Yolanda, Sam
about living
Yolanda, Sam
Since the names Yolanda and Sam are the only items in the list, they do not need to be separated by a comma. We use the conjunction "and" to combine items in a two-item list, so "Yolanda, Sam" should be changed to "Yolanda and Sam." If Yolanda and Sam had a third friend, named, say, Suzannah, then commas would be needed to separate each name in the list.
