I'm a bit stuck as in one question of a CIE Primary English exam students have to decide what a phrase is an example of (the underlined part below). They can choose from: alliteration, imagery, metaphor, simile or personification. The answer in the mark scheme is "imagery", but I would have ticked "metaphor". "All my life I had thought he would have a predatory look of an ancient crow under the shadow of his sou’wester." Help!
