Answer:
Flung
Step-by-step explanation:
In this case, the idiom that would best complete the sentence is "to fling aside." This refers to the action of tossing or slinging something or someone out of the way. It also refers to tossing something out of one's own path. The idiom conveys a sense of impatience or annoyance. In this example, Max is tossing the book aside due to his annoyance at the fact that the poem makes little sense to him.
