Example Question #1 : Identifying Apostrophe Errors

Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.

The boy's teacher had forgotten to correct their homework; she had spent the entire night planning the new geography lesson. No error

Possible Answers:

The boy's

had forgotten

homework; she

planning

No error

Correct answer:

The boy's

Explanation:

Be watchful of possessive plural nouns: here, the correct apostrophe will be at the end of the word: "boys'" is correct because the subject is plural.

Example Question #1 : Identifying Apostrophe Errors

Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.

Alyssa collected hundreds of childrens' hats, scarves, gloves, and coats for the local shelter's winter clothing drive. No error

Possible Answers:

shelter's

hundreds of

gloves and,

No error

childrens'

Correct answer:

childrens'

Explanation:

The correct possessive form for "children" is "children's," not "childrens." "Children" is a noun that changes form in plural, from "child" to "children" instead of "childs." In irregular plural nouns that do not end in "s," you need to add an apostrophe followed by an "s" to form the possessive form of the word. For plural nouns ending in "s" such as "girls," you need to add the apostrophe at the end, but not an "s." For example, the possessive of "girls" is "girls'."

Example Question #2 : Identifying Apostrophe Errors

Select the underlined word or phrase that needs to be changed to make the sentence correct. Some sentences contain no error at all.

Possible Answers:

More often than not

the Davis's 

could expect

No error

their

Correct answer:

the Davis's 

Explanation:

The above sentence's error is "the Davis's," as "Davis" is not a possessive noun in this case and therefore does not need an apostrophe.

Possible Answers:

girl's

practice; they

as soon as 

No error

Correct answer:

girl's

Explanation:

The sentence indicates that there is more than one girl on the team by using the word "they;" therefore, "the girl's" needs to be changed to "the girls'" in order to reflect the correct possessive plural form.

Example Question #1 : Identifying Apostrophe Errors

Select the underlined word or words that need to be changed to make the sentence correct. Some sentences may not contain an error.

Scientists have been tracking the Canadian geeses’ migratory patterns for the better part of thirty years, and they have begun to notice some unusual habits. No error.

Possible Answers:

have been tracking

have begun

No error.

geeses'

the better

Correct answer:

geeses'

Explanation:

The plural of goose is “geese,” not “geeses,” so the correct possessive form would be “geese’s.” "The better part of" is a commonly used phrase, and "have been tracking" and "have begun" are both the correct forms of the present perfect.

Example Question #81 : Identifying Punctuation Errors: Other Punctuation

Select the underlined word or words that need to be changed to make the sentence correct. Some sentences may not contain an error.

Everyone at the hospital was complaining bitterly about the new overtime policy; the nurse’s station in particular was a hotbed of dissent. No error.

Possible Answers:

nurse's station

about

dissent.

No error.

policy;

Correct answer:

nurse's station

Explanation:

Because multiple nurses work at the hospital, we need a plural possessive: “nurses’ station” is the correct form. Elsewhere in the sentence, “about” is the correct preposition to use with “complaining,” “dissent” is a word that means strong disagreement, and the semicolon is used correctly to separate two independent clauses.

Example Question #1 : Identifying Apostrophe Errors

Select the underlined word or words that need to be changed to make the sentence correct. Some sentences may not contain an error.

The fervency of the congregation’s prayers was felt by everyone at the service as Our Father’s rang out left and right. No error.

Possible Answers:

Our Father's

congregation's

as

No error.

fervency

Correct answer:

Our Father's

Explanation:

The correct plural of “Our Father” is “Our Fathers.” No apostrophe is used to form the plural. Because there’s only one congregation at the service, “congregation’s” is the correct possessive.

Example Question #82 : Identifying Punctuation Errors: Other Punctuation

Select the underlined word or words that need to be changed to make the sentence correct. Some sentences may not contain an error.

Journalists and animal enthusiasts alike flocked to the wolf's enclosure to gawk at the pack’s newest litter. No error.

Possible Answers:

alike

gawk at

pack's

wolf's

No error.

Correct answer:

wolf's

Explanation:

Because there’s an entire pack of wolves (and some new pups!), the singular possessive “wolf’s enclosure” should actually be “wolves’ enclosure.” “Pack’s” has the correct apostrophe form.

Correct answer:

loafs'

The correct plural of loaf is loaves, not loafs, so the possessive should be loaves’, not loafs’.
