Answer:
"This is a bear of a lesson"
Step-by-step explanation:
"The wind exhaled" is a personification
"This is a bear of a lesson" is more of you comparing something
"I have been hungry for weeks" isn't a metaphor because it isn't REALLY over exaggerating, though it could still be a metaphor.
"This lesson is like a bear" is a simile because it uses "is"
if you need more help just ask : )
