Which technique is the author using in this passage to reveal character traits

I think the complete question would be;

Which technique is the author using in this passage to reveal the character’s traits?

passage from the grapes of wrath muley’s face was smooth and unwrinkled, but it wore the hateful look of a bad child. the mouth was held tight and small, the little eyes half scowling, half fretful.

is:

the Imagery used in describing the details about the face, and the metaphor used in comparing it to a child's face. These details tell the reader about the character's personality.

uncanny would be like unlucky or disaster. you can look for more in the dictionary or if you have text book then turn to a. 17 but it's different with textbooks.

are there multiple choice options?
