Read the following article and select the best answer. Article: Today I was at the mall waiting for friends, when a lady wearing a knit hat and a sweater came up to me and, shivering, said, "I'm homeless. Would you mind buying me some food?" In that split second, everything I'd learned since kindergarten flashed through my mind. Don't talk to strangers ... Be a good citizen ... People will take advantage of you ... Treat others as you wish to be treated ... The greatest thing you'll ever learn is just to love and be loved in return ... I guess love won the debate. "Sure," I said. "What would you like?" She thought and then said, "I'd like to get Chinese food." We headed upstairs. On the way she told me about when she was a teenager. She remembers taking pictures for the yearbook with her best friend. She was in the band and played basketball. She got good grades and was a good student. She ordered soup, an egg roll, white rice, and pepper chicken. I would normally think that was a lot, but she had probably barely eaten in the last few days. I got my usual - lo mein and General Tso's chicken. As we ate, we got to know each other. She asked if I played any instruments. I replied that I played the violin, cello, and guitar. She told me she played the flute, piano, guitar, and violin. In the middle of our meal, I realized something. And she thought of it at exactly the same time. "So, what's your name?" she asked. "I'm Claire," I said, startled at our exact same thought. "What's yours?" "Joyce," she said with a smile. We continued talking, and she asked my favorite subjects in school and if I wanted to go to college. "Hopefully," I replied. "I'm interested in nursing." "I went to college for nursing," she said. I was taken aback. How could we have so much in common? Was she pretending so I'd feel sympathy for her? But her eyes were genuine as she said this. Meanwhile I was eating my lo mein, picking around the cabbage and the other vegetables. Joyce said, "If you don't like it you can take it back." I told her that I liked it, but was not fond of the vegetables. She broke... Question: Why did Joyce end up unemployed and homeless? - She was a victim of high education - She actually had some kind of mental disorder - She graduated with average grades - The reason is not yet given.
The reason is not yet given.
