The statement, "When the writer met Jerry at the orphanage, he was years old," implies a specific age for Jerry at the time of their meeting. The correct answer, 'd: eight,' signifies that Jerry was eight years old. This choice helps to create a clear understanding of Jerry’s childhood and the context of the orphanage setting, which often serves as a place for younger children who are in need of care and support.

Choosing eight as the age reflects the innocence and vulnerability of a child who might be living in an orphanage. It sets a tone for the relationship between the writer and Jerry, suggesting a formative experience that could impact both of their lives significantly. The other options—ten, twelve, and fourteen—suggest a more mature age, which could shift the dynamics of their interaction away from the typical experiences found among younger children, such as playfulness, naivety, and a sense of discovery.

Overall, selecting 'eight' provides insight into Jerry's character, the emotional depth of the story, and the poignant atmosphere of the orphanage, aligning perfectly with the themes of childhood and connection inherent in such narratives.
