Step-by-step explanation:
In this passage, the author employs foreshadowing. Foreshadowing is a literary device in which an author gives the reader a hint of what is going to happen later in the story. In this text, after we learn about the time, we lear that there is enough time for the characters to accomplish what they desire. The promise of accomplishment, as well as the cheerful tone, contribute to creating a tone of excitement in the text.
