Read the following poem and give answers to the given questions. 

The way a crow

 Shook down on me

 The dust of snow

 From a hemlock tree

 Has given my heart

 A change of mood

And saved some part

Of a day I had rued.

Q:

What uplifted his mood?

• 1
  falling of snow on his shoulder
• 2
  the crow
• 3
  hemlock tree
• 4
  all of the above
