Question

identify examples of personification and the effect that they have on the meaning and tone of the text

Answer 1

You will need to provide the text that you are analysing for a specific answer, but basically, you are looking for any time where the author has used describing words that you would use for humans on object or animal, or where the author is making the object/animal use human characteristics like speech.
the effect that this may have on the piece could be that it creates a friendlier atmosphere if the object/animals are described in a positive and useful way but it can work in reverse as well.
