Final answer:
The passage describes Amy reflecting on her own beauty and desires for the future, not about a dare given to Annie at Amelia's sleepover.
Step-by-step explanation:
The passage you provided does not include a specific event at Amelia's sleepover; rather, it describes Amy's personal reflections and aspirations as she gazes at herself in the mirror after the festivities of the sleepover. Amy finds herself inspired by a picture of a girl who had only her beauty but yearned for happiness.
Amy adorns herself with scarves, indulges in a moment of vanity, and vocalizes her desires for a joyous and affluent life, full of admirers and opportunities. This intimate moment of self-contemplation illustrates Amy's dreams and the beginnings of her envisioning a future for herself and her loved ones. There is no mention of a dare involving Annie or any action she took.
