Read this short excerpt from an online article:
SEOUL, South Korea - After my older brother fell ill from the stress of being a student in South Korea, my mother decided to move me from our home in Seoul to Vancouver for high school to spare me the intense pressure to succeed. She did not want me to suffer like my brother, who had a chest pain that doctors could not diagnose and an allergy so severe he needed to have shots at home.
What part of aspect of his brother's development do you think needs to be addressed?
