which sentence shows correct subject- verb agreement? A. My friend and her mother were listening to the radio. B. My friend and her mother was listening to the radio.
A is correct because "my friend and her mother" can be substituted by the pronoun "they" which is plural, therefore the plural verb needs to be used, which is "were".
A is correct. this is because more than one person was listening to the radio (my friend AND her mom) so you would use were as a plural tense rather than was because was refers to only one person using the radio. i hope this helped!!!!
