Which word set completes the analogy? chat : talk : :

sigh : frustrated pain : moan sorrow : tears scribble : write

The correct answer is "scribble: write."

The word set that completes the analogy is "scribble: write."

To chat is to have a light informal conversation with another person. It could be person to person or using an electronic device as Watts up or any social media chat. To talk is to have a more formal or serious conversation with another person.  

The set that completes the analogy is "scribble: word." To scribble is to draw or write something very quickly without paying much attention to the style. It could be a careless piece of drawing. On the other hand, to write is to make marks that represent words that have some meaning.

the swan might be a metaphor for our soul, which is ancient and timeless. the speaker wants to know where it's going and what it wants, what's the purpose in life. he asks our soul to follow him in knowing that god is us and the answer to the question "who am i" that was written on the wind of god's whim to know himself that blew over his being in the beginning of creation. and to connect to god consciously on the path to knowing him is the joy of loving him, like a bee that will grow and end our sorrows by ending desire. in that connection there is no doubt about god and existing forever.
