Fischel and Paul use imagery to describe their approach to exam questions, comparing it "with Martin Handford and his wonderful drawings that hide Waldo in a maze of design and color." Here, they are emphasizing the complex nature of the questions.
Battle imagery
Fischel and Paul often use imagery that suggests the law exam is a kind of "battle." For example, "our colleagues often remind us that spotting an issue is only half the battle and that many students fall down when the task turns to analysis."

Fischel and Paul state their objectives for the section "Issues in Living Color," in which they "seek to explain why issues (rather than merely chaos and confusion) lurk within those long hypotheticals." By using the word "lurk," the professors suggest that the hidden nature of these issues within the exam questions.
