Example Question #1 : Identifying Punctuation Errors: Other Commas
Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.
In the interest of advancing her career, Ollie decided to stop going out on the weekends, and spend more time in the office. No error.
decided
No error.
weekends, and
more time
advancing her career
weekends, and
This sentence has a comma before the last phrase, but that phrase does not have its own subject. A comma here is therefore not necessary. The corrected sentence reads, "In the interest of advancing her career, Ollie decided to stop going out on the weekends and spend more time in the office."
Example Question #2 : Identifying Punctuation Errors: Other Commas
Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.
The trouble with taffy, is that it requires huge quantities of sugar. No error.
it
huge quantities
taffy, is
No error.
trouble with
taffy, is
This sentence has an unnecessary comma separating the subject and predicate of the sentence. This should only happen if there is an interrupting phrase, and there isn't one in this sentence. The corrected sentence reads, "The trouble with taffy is that it requires huge quantities of sugar."
Example Question #3 : Identifying Punctuation Errors: Other Commas
Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.
Forgetting the key part of the instructions, Charlie preheated the oven, but did not prepare the cake. No error
No error
did not prepare
instructions, Charlie
key
oven, but
oven, but
This sentence has an unnecessary comma. Use commas to separate compound sentences, but not compound predicates like we have here. The corrected sentence reads, "Forgetting the key part of the instructions, Charlie preheated the oven but did not prepare the cake."
Example Question #2 : Identifying Punctuation Errors: Other Commas
Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.
The man who usually sits on the park bench every afternoon, was not there last Tuesday. No error
on the park bench
who
afternoon, was
last Tuesday
No error
afternoon, was
This sentence has a problem with commas. The comma between “afternoon” and “was” is not necessary because it is not setting off a nonrestrictive clause. It creates an awkward pause in the middle of the sentence. The corrected sentence reads, "The man who usually sits on the park bench every afternoon was not there last Tuesday."
