Love and Friendship 
 by Emily Brontë.
 Love is like the wild rose-briar, 
 Friendship is like the holly-tree— 
 The holly is dark when the rose-briar blooms 
 But which will bloom most constantly?
 The wild rose-briar is sweet in spring, 
 Its summer blossoms scent the air; 
 yet wait till winter comes again 
 And who will call the wild-briar fair?
 What types of symbols are the wild rose-briar and the holly-tree in this poem?
 a.supporting
 b.summarizing
 c.personal
 d.conventional
