Question

I need help on this I am very confused

Answer 1

For similes, your comparing using like or as, for metaphors, your comparing without using like or as. So in this your just inserting words (that make since, of course) I'll give you the first to answers to Similes and Metaphors, if you need any more help you can let me know. 

Simile-A friend is like a ice cream cone, or Friendship is like a mountain.

Metaphor-A friend is a sibling.
