1. which of the following sentences is correct? a. today we celebrate abraham lincoln, to who this monument was raised. b. today we celebrate abraham lincoln, to whom this monument was raised. c. today we celebrate abraham lincoln, to whose this monument was raised. 2. which is the antecedent of the capitalized pronoun in the sentence below? jason and his friends listened to the speaker carefully and then asked her a few questions. a. jason b. his friends c. the speaker 3. choose the correct pronoun to complete the sentence below. mrs. chen offered both her friends a ride in her car, but they preferred to use a. hers b. they c. theirs

1. b. Today we celebrate Abraham Lincoln, to whom this monument was raised.

This option is  correct because it contains the pronoun "whom". "Whom" is an objective pronoun that is used when talking about the object rather than the subject of the sentence. In this case, Abraham Lincoln is the object of the sentence and thus, the objective pronoun "whom" is most accurate when talking about him.

2. c. the speaker 

The speaker is the antecedent of the pronoun "her" in the sentence, "Jason and his friends listened to the speaker carefully and then asked her a few 
questions."

 This is because "her" cannot be the pronoun associated with Jason (a male), nor his friends, because their gender is not specified, and additionally a group of friends (plural) cannot be the antecedent of the singular pronoun "her". 

3. c. theirs

 a. "hers" cannot be the correct option since Mrs. Chen's friends refused the offer to ride in her car.
b. "they" is also incorrect because the pronoun "they" cannot be used when referring to the friends' cars. We say "their cars" instead of "they cars" because "their" indicates possessiveness, demonstrating that the cars belong to the two friends respectively. This is why option c."theirs" is the correct answer.
