How does the author use foreshadowing in The Last Question?

Parker's poems often portray tough, cynical, world-wise women..... women who don't believe their own words, and women who long for love, even though they know intellectually that it is unlikely or impossible. This kind of passivity helps to create tension in The Last Question, as well as to foreshadow the tragedy to come. For the speaker to know that an unacceptable outcome is arriving, and that she is unable to do anything about it, is cause of great frustration. The speaker, however, seems committed to her new love.... at least for the time being, and thus, she consciously does things that she herself regards as against her own interests.
