A because you can see the kings kindness has changed him
Based on the given statement above, I can say that the type of comparison that is being shown is a SIMILE. A simile is a literary technique that compares two unlike objects with the use of the words "like" or "as...as". Apparently, this uses "as...as" in comparing "they" and "bark of a tree". Hope this helps.
The answer could be a pun??
