Final answer:
The question regarding the Ung children is unclear as it seems to confuse different narratives. In 'Riders of the Purple Sage', there are no Ung children, while in 'First They Killed My Father', they seek safety and normalcy, often met with harsh realities as opposed to their expectations.
Step-by-step explanation:
It appears there is a confusion regarding the passage or book related information in your question, it is not clear which text the Ung children are from; however, the excerpts provided seem to relate to different works. For example, the first passage about Jane Withersteen and Fay is from the novel 'Riders of the Purple Sage' by Zane Grey. If we refer to this text, the 'Ung children' are not part of this narrative. Alternatively, if you are referring to 'First They Killed My Father' by Loung Ung, this question could then be about a different story. In this memoir, the Ung children are seeking safety and a semblance of normalcy amidst the Cambodian genocide. When they find a foster family after being separated from their parents, Loung Ung expects stability and compassion but is often faced with harsh treatment and disappointment, contrasting her expectations of familial warmth. However, without a specific reference to the 'Ung children' in the provided chapters, it is challenging to provide an accurate answer to your question.
