This question asks for your personal feelings, so each student’s answer will be different. A model answer could be:
I once knew someone very much like the author’s grandmother – my own grandmother. She lived a simple, disciplined life, prayed regularly and always put the family first. When she passed away, I felt a deep emptiness at home. Even now, whenever I remember her voice, her stories and her quiet presence, I feel the same sense of loss that the author felt for his grandmother. At the same time, her memory gives me strength and comfort.
