The best answer for the first question would be alliteration, because the letter W occurs in consecutive and/or adjacent words in the sentence "Watch the way the word-web weaves".
For the second question, the best answer would be hyperbole, since the sentence contains exaggeration.
For the third question, the best answer would be personification, since a human element is added to inanimate objects.
Hope my answer has come to your help.
