Iam failing a class and my mother keeps putting me in grounding of not going anywhere and even talking to my foster siblings. even though the foster sister is failing three classes and can do whatever. the foster sister is also the favorite and never gets grounded and is allowed to do whatever she wants to us like hit us and get us in trouble for no reason. she is 17. idk what to do i'm considering running away.

idk how you get this but its hard for me : c

explanation: the line "to save the day, harry must get past a scary three-headed guard dog" from the summary best justifies the conclusion that harry potter and the sorcerer’s stone was influenced by ancient greek mythological literature. the three other choices had nothing to do with ancient greek literature - and the words "three-headed guard dog" are what makes that choice the correct answer.
