Final answer:
Annie gained resilience and determination from her painful childhood, as indicated by her ability to remain unfazed by harsh circumstances and to work hard with contentment in New York.
Step-by-step explanation:
A student has asked about the strengths Annie gained from her experience with a painful childhood. Considering the context provided, it seems that resilience and determination would best describe the strengths developed by someone who had an adverse early life. This assessment comes from the last piece of the reference material provided where we see a description of Annie as unfazed by her harsh circumstances, showing fortitude by working hard and being content with little social interaction in New York. Resilience is a person's ability to withstand or recover quickly from difficult conditions, and determination relates to the persistence she may have shown in facing life's challenges. These traits are often born out of necessity in tough times, as we can surmise from the narrative given.
Therefore, the correct answer to the question 'What strengths did Annie gain from her experience with a painful childhood?' would be B) Resilience and determination.
