A possessive pronoun shows who owns or has something.

The first sentence tells us that the kite belongs to "me". "Me" is a possessive noun. The correct possessive pronoun that goes with "me" is "my". 

The correct answer is "his." This sentence requires a singular possessive pronoun, because in this sentence, the chair belongs to the man. The only option that fits as both singular and possessive is "his."

The correct answer is "her." Since the subject is a singular female, the pronoun also needs to be singular and feminine. "Its" and "his" are singular, but aren't feminine, and "their" is plural.  The only choice that is singular and feminine is "her," so it is the best choice. 

The correct answer is "her." This pronoun refers to the subject, "she," which is singular and feminine, so the pronoun must also be singular and feminine. It also needs to be a possessive pronoun, since the pronoun describes something that belongs to the subject of the sentence ("her friend"). The only choice that fits these descriptions is "her," so it is the best choice. 

The correct answer is "its." This sentence requires a singular pronoun to agree with the subject, "apartment" which is singular, therefore, the choice "their," which is plural, is incorrect. The word apartment does not have a gender, so we do not use "his" or "her." That is why the best choice is "its."

This question is a simple interrogation of correct pronoun usage. The only possible correct answer is thus "her" since "Kathy" is the object of the second main clause. 

In this sentence, the subject/noun that is being replaced is Rebecca. It can be assumed that Rebecca is a female name, so the most appropriate pronoun to replace it is "she." "They" refers to a group of people, "he" is used for males, and "it" would refer to something previously mentioned or easily identified, so in this instance, "she" is the best fit.

In this sentence, the subject/noun that is being replaced is "the nurses". It can be assumed that "the nurses" is referring to a group of nurses or multiple nurses because of the -s ending, so the most appropriate pronoun to replace the noun is "they." "They" refers to a group of people, "he" is used for males, "she" is used for females, and "it" would refer to something previously mentioned or easily identified, so in this instance, "they" is the best fit.

In this sentence, the subject/noun that is being replaced is "the yogurt". It can be assumed that "the yogurt" is something recognizable, and because of the first sentence, it is something that has been made known, so the most appropriate pronoun to replace it is "it." "They" refers to a group of people, "he" is used for males, and "it" would refer to something previously mentioned or easily identified, so in this instance, "it" is the best fit.

In this sentence, the subject/noun that is being replaced is Gregory. It can be assumed that Gregory is a male name, so the most appropriate pronoun to replace it is “he.” The sentence mentions that the dog is "his" dog which also hints that Gregory is a male. “They” refers to a group of people, "she" is used for females, “he” is used for males, and “it” would refer to something previously mentioned or easily identified, so in this instance, “he” is the best fit.
