There, Their, And They're

The correct answer is "There". In this sentence, "There" is used as an adverb to indicate the existence or presence of someone in the room. "Their" is a possessive pronoun used to show ownership, and "They're" is a contraction of "they are".

The correct answer is "Their" because it is the possessive form of the pronoun "they". In this sentence, the subject "they" is indicating that someone lost their cat. "There" is used to indicate a location, "their" shows possession, and "they're" is a contraction of "they are" which does not fit in this context.

The correct answer is "Their" because it is the possessive form of "they" and indicates that the books belong to a specific group of people.

The correct answer is "They're". In this sentence, the speaker expresses surprise and disbelief that a certain group of people is not on the road yet. "They're" is the contraction of "they are", which indicates that the speaker expected the group to be present at the current time.

The correct answer is "They're". In this sentence, the speaker is expressing excitement about watching the Saprissa vs. La Liga game and mentioning that "they" are playing in Alajuela today. "They're" is the contraction of "they are," which correctly indicates that the teams are playing in Alajuela.

The correct answer is "There". In this context, "there" is used to indicate a place or location. It is the correct choice because the other options, "their" and "they're", do not make sense in this sentence.
