Article: Well I decided to cut my front lawn today, especially since I live on a main street downtown with lots of traffic. Anyway, I finished mine and decided to cut my neighbor--Jean's grass while I was at it. She is a sweet person who has gone through some _ times in the last year. Her brother passed away of cancer last year; her sister (who lives with her) is mentally challenged--yet so sweet! It was a difficult time with physical and mental challenges that led her employer in our local hospital to let her go after 25 years of service! Lastly, my neighbor Jean, who is a nurse in our local hospital, was diagnosed with esophageal cancer in December. She went through radiation and a long recovery--but thankful she is in remission . Anyway, in short I was leaving my house this afternoon and she stopped me to thank me for cutting her grass. She told me her dad passed away on Friday and she just arrived home from the funeral service, so she didn't know when I would have time to cut her grass. So, when she arrived home and saw it cut she was more than happy and grateful! I said to her "You are welcome, just a small act of kindness for a neighbor." I did it for exercise and shared pleasure not knowing it meant more to her than just doing a neighbor a favor!
Question: Although a lot of unfortunate matters happened to Jean, she is still _ .
Options: (A) pessimistic (B) optimistic (C) depressed (D) disappointed

Ex Output:
B

Article: Can you imagine exchanging the pleasure of city life for a quiet life in the countryside? Many people want to move from the country to the city because they think that life in the city is more exciting and better than that in countryside, especially young people who like new, modern things.

Other people are interested in technological things and high-tech jobs and think they can only find them in big cities.

Article: Dear son, The day that you see me old and I am already not in good health, have patience and try to understand me. If I get dirty when eating, if I can not dress, have patience and remember the hours I spent teaching it to you. If, when I speak to you, I repeat the same things thousand and one times, do not interrupt me, listen to me. When you were small, I had to read to you thousand and one times the same story until you got to sleep. When I do not want to have a shower, neither shame me nor scold me. Remember when I had to chase you with thousand excuses I invented, in order that you wanted to breathe. When you see my knowing little about new technologies, give me the necessary time and do not look at me with your mocking smile. I taught you how to do so many things: to eat good, to dress well, to confront life... When at some moment I lose the memory or the thread of our conversation, let me have the necessary time to remember, and if I cannot do it, do not become nervous, as the most important thing is not our conversation but surely to be with you and to have you listening to me. If ever I do not want to eat, do not force me. I know well when I need to and when not. When my tired legs do not allow me to walk, give me your hand, the same way I did when you made your first step. And when someday I say to you that I do not want to live anymore--that I want to rest forever, do not get angry. Someday you will understand. Try to understand that _ . Some day you will discover that, despite my mistakes, I always wanted the best thing for you and that I tried to prepare the way for you. You must not feel sad, angry or impotent for seeing me near you. You must be next to me, try to understand me and to help me as I did it when you starting living. I will pay you by a smile and by the immense love I have had always for you.
