Example Input: Article: Several overseas trips with the family have taught us that they can be rewarding, but you always have to be careful of pickpockets. On a lovely visit to Paris an encounter with a pickpocket gave the would-be thief a little more than he _ While walking down the famous Champs Elysee, I was astonished to feel someone unzip my handbag and remove my purse. I turned to glimpse a young man turning away and pretending to be absorbed in the mouth-watering contents on display in a bakery window. Being only a teenager at the time, I had no idea what to do. So I tapped the young man in question on the shoulder and said. "Excuse me can you please give me back my purse?" Of course the pickpocket had no idea what I was saying (and didn't want to know) and proceeded to shrug his shoulders and basically say (in French) "I don't speak English"? Meanwhile my Mother (a Scotswoman with a bad temper), came to see why I had stopped walking and what was going on. When I informed her of the situation she lost control and started yelling at the thief who still stood there making gestures in French while a crazy Scotswoman harangued him. At this stage we were starting to attract onlookers, and when my Mother started hitting the young man with her handbag the would-be thief decided it was time to get away. Luckily, amid all the disorder the thief lost his control of my purse, and as he made a break-for-it, my purse dropped to the ground! I quickly snatched it up and for the rest of vacation we walked around with our handbags clutched against our chests!

Example Input: Article: I have two sons. They are as different as night and day. My youngest is sweet, loveable, easy-going, and finds joy in everything. My oldest we've nicknamed the "Evil Genius" is ambitious, self-confident, and suffers no fools. Whenever we mentioned Santa my husband and I were rewarded with major eye rolling and deep sighs from my oldest. At first we both tried to ignore it. We both knew that our eldest had figured out the big secret. But I'd be damned if he was going to ruin it for his six-year-old brother who had plenty of Santa-loving years ahead of him. I looked at my husband in the eye and said, "I'll handle this." to which he responded "Okay just be careful because I'm not sure he knows - he might just be acting like it." But I knew. And I had it in my mind that he was about to break his younger brothers spirit and break the news to him. I was afraid he was going to take the Christmas spirit away from my sweet innocent youngest and stamp all over it. I had to protect him. I needed to control this now before it got out of control. I rushed into the play room where my oldest was playing alone. I looked him dead in the eyes and said: "Well you know Santa isn't real, right?" And as I stared at my eight-year-old son for what seemed like a long time of silence, his eyes started to fill with tears. And a tear dropped down his cheek when he screamed out, "He's not?" "Um well it's not that he's not real (shut up you idiot - stop saying he's not real), but he doesn't really make and deliver all the toys. Dad and I get some of them for you. So he's real. He's just got a little help from us." _ . He just sat there looking at me with an expression of doubt. You know when you make a terrible mistake but you can't stop yourself from making it worse? That was me because I just had to know. I had to know why he had seemed to be over Santa. So I asked him why he rolled his eyes and sighed every time his father and I mentioned Santa. To which he replied that kids at school had been saying Santa wasn't real but that he still thought he was.

Example Input: Article: Children today spend less time outdoors than ever before and it may be harmful not only to their physical health, but also to their cognitive development. A year-long study, recently published in the Sciences, found that elementary school children who were exposed to more green space within or directly outside their school showed improved learning and memory. The findings reinforce that of a recent six-year study on 905 Massachusetts public elementary schools, which found that students in schools that had more "greenness" in their surroundings reported higher scores on standardized testing in English and math. "There is an expanding body of scientific evidence linking the human experience in the natural world to better physical and mental health and improved cognitive abilities," journalist Richard Louv, co-founder of the Children & Nature Network, said in an email to The Huffington Post. "An increasing number of homeschoolers, nature preschools, independent primary and secondary schools, and forward-thinking public schools are incorporating nature experience into learning." The new study was conducted on more than 2,500 children in second, third and fourth grade at 36 primary schools in Barcelona, Spain. Researchers found that the students who attended schools with more green space showed a 5 percent improvement in the short-term memory that's critical for reasoning, learning and comprehension. But their inattentiveness decreased slightly. Spending time outside could have a number of benefits for children beyond improved memory and attention. Another recent study found that adventurous outdoor play such as climbing, rough and tumble play, and exploring alone improves children's physical health while also help them develop creativity and social skills greatly. Some schools are starting to take notice, creating more space for children to enjoy being in nature, including community gardens, outdoor playgrounds and small parks.
Question: What did the study lasting a year find?
Options: (A) The cognitive abilities of children today decreased. (B) The findings of another six-year study were incorrect. (C) Being exposed to nature was beneficial to the learning of pupils. (D) Students had higher scores on testing in English and math than before.
