Input: Consider Input: 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

Output: B

Input: Consider Input: Article: Nature is full of color, from rainbows and roses to butterfly wings and peacock tails. Even the fruits and vegetables you eat have different colors: blue blueberries, red strawberries, green broccoli, and orange carrots. Plant and animals often use color to attract attention. The substances responsible for these colors belong to a class of chemical called antioxidants . Plants make antioxidant to protect themselves from the sun's ultraviolet(UV) light. Ultraviolet light causes chemicals called free radicals to form within plant cells. They can destroy parts of plant. Free radicals also have damaging effects on human beings. Some of these effects like wrinkled skin can be seen. The damage is caused by the free radicals attacking cells in our bodies. Certain cancers and heart disease are linked to free radicals. Our bodies have natural defences for fighting off free radicals. While we are young, our defences are pretty strong. However, they get weaker as we get older. The body's built-in defences can only go so far without extra help. The key to fighting free radicals with fruits and vegetables is to mix and match colors. It's like sunscreen for the inside of your body. Go for a range of very bright colors. Colorful foods contain hundreds of healthy chemicals not found anywhere else. Research into how chemicals in blueberries affect the brain's function in rats suggests that these chemicals may help our own brains work more efficiently. Don't just blame the sun. Ultraviolet light isn't the only source of free radicals. If you breathe polluted air such as smog, automobile exhaust , or wasted gas from a factory, you take in chemicals that also cause such damage. And, the body itself produces free radicals as it processes food.
Question: Which of the following not true?
Options: (A) Antioxidants are responsible for plant colors (B) Plants use color to attract attention (C) Antioxidants can protect plants from UV light (D) Antioxidants help free radicals to attack plants

Output: D
