I am pretty sure that themes on which William Folkner focuses and takes as a basis of his masterpieces are definitely : love, honor, compassion, and sacrifice. First of all, there is a prompt in question that is put in quotation marks. Love and compassion are the points which always were in need for people's relationships and honor with sacrifice, as told by Folkner in many of his works, are connected to more global sphere of demand - they are universal issues.
Is there choices like A BC and stuff ?
The best answer would be "She evinced an interest in drama, so I took her to the play."
The definition for evinced is to show or express clearly. So, this is the only answer that makes sense.
I hope this helps!
