Final answer:
The question is about foreshadowing the racial backgrounds of Desiree and Armand in Kate Chopin's 'Desiree's Baby.' The provided passages do not seem to be from this story and therefore do not offer the necessary quotes or reasons to answer the question accurately.
Step-by-step explanation:
The question seems to be referring to the backstory of characters in a narrative, possibly from a novel or short story, which would fall under the English literature category. However, the key detail here is that the question mentions foreshadowing that Desiree was white and Armand was not, which is a clear reference to Kate Chopin's short story 'Desiree's Baby'. The story is set in the Antebellum South and deals with issues of race and identity. It is a classic example used to illustrate the literary device of foreshadowing. Unfortunately, from the passages provided, none explicitly showcase the foreshadowing in question pertaining to Desiree and Armand's racial backgrounds.
To accurately provide three instances of foreshadowing from the story, one must refer directly to the text of 'Desiree's Baby' by Kate Chopin, which depicts how Desiree's background is shrouded in mystery and how Armand's behavior and the setting foretell the twist regarding their races. Without direct excerpts from the actual story, it is impossible to provide the precise instances of foreshadowing required by the question based on the provided references, which appear to be from different texts and do not relate directly to 'Desiree's Baby'.
