1. Squeaky was a skinny girl with a squeaky voice -

which, of course, is how she got her nickname.

Direct or indirect?

The correct answer is: direct characterization.

Explanation:

In literature, characters of a text can be portrayed by the author using either direct or indirect characterization. Direct characterization involves directly telling the reader the personality traits of a character. Indirect characterization on the other hand involves showing rather than telling the reader the character's personality through dialogues, actions, and they way the character is perceived by others, and so on.

The instance in the question is an instance of direct characterization as the author directly tells (rather than shows) the reader about Squeaky's characteristics by saying that Squeaky is skinny and has a squeaky voice.
