from lloyd alexander, the book of three. copyright 1964 by lloyd alexander
what is the effect of the metaphor on the passages meaning or tone?
it indicates dallbens beard is big and bushy.
it suggests dallben has a stormy personality.
it implies dallben has bad eyesight.

Explanation:

A metaphor compares two unlike things without using "like" or "as". Here, the beard is compared to a cloud. A cloud is large and covers a significant area. So, this metaphor emphasizes the size and bushy nature of the beard. There is no indication in the text about a stormy personality (no words related to anger or turbulence) or bad eyesight (the action of closing eyes is for meditating, not due to poor vision).

Answer:

It indicates Dallben's beard is big and bushy.
