Input: Consider Input: Article: The fact that blind people can see things using parts of their bodies apart from their eyes may help us to understand our feelings about color.If they can sense color differences, then perhaps we, too, are affected by color without knowing it.Salesmen have discovered by experience over a long period of time that sugar sells badly in green wrappings, that blue foods are considered not agreeable to the taste, and that cosmetics should never be packed in brown.These discoveries have grown into a whole subject of color psychology. Some of our preferences are clearly psychological.Dark blue is the color of the night sky and therefore connected with calm, while yellow is a day color connected with energy and encouragement.Experiments have shown that colors, partly because they are connected with psychology, also have a direct effect on people's mind.People in bright red surroundings show an increase in breathing speed, heartbeat and blood pressure.Red is exciting.Pure blue has exactly the opposite effect; it is a calming color.Being exciting, red was chosen as the signal for danger, but a closer study shows that a bright yellow can produce a more basic state of alarm, so fire engines in some advanced areas are now rushing around in bright yellow colors that stop buses, trucks and cars.
Answer: found out that colors affect sales

Output: The passage tells us that salesmen have _ .

Input: Consider Input: Article: A man came home from work late, tired and irritated, to find his 5-year-old son waiting for him at the door. "Daddy, may I ask you a question?" "Yeah sure, what is it?" replied the man. "Daddy, how much do you make an hour?" "That's none of your business. Why do you ask such a thing?" the man said angrily. "I just want to know. Please tell me. How much do you make an hour?" pleaded the little boy. "If you must know, I make $20 an hour." "Oh," the little boy replied, with his head down. Looking up, he said, "Daddy, may I please borrow $10?" The father was furious, "If the only reason you asked that is so you can borrow some money to buy a silly toy or some other nonsense, then you march yourself straight to your room and go to bed. Think about why you are being so selfish. I don't work hard every day for such childish behavior." The little boy quietly went to his room and shut the door. The man sat down and started to get even angrier about the little boy's questions. How dare he ask such questions only to get some money? About an hour or so, the man had calmed down, and started to think: maybe there was something he really needed to buy with that $10 and he really didn't ask for money very often. The man went to the door of the little boy's room and opened the door. "Are you asleep, son?" He asked. "No daddy, I'm awake," replied the boy. "I've been thinking, maybe I was too hard on you earlier," said the man. "It's been a long day and I took out my aggravation on you. Here's the $10 you asked for." The little boy sat straight up, smiling. "Oh, thank you, daddy!" he yelled. Then, reaching under his pillow he pulled out some crumpled up bills. The man, seeing that the boy already had money, started to get angry again. The little boy counted out his money, then looked up at his father. "Why do you want more money if you already have some?" the father grumbled. "Because I didn't have enough, but now I do," the little boy replied. "Daddy, I have $20 now. Can I buy an hour of your time? Please come home early tomorrow. I would like to have dinner with you."

Input: Consider Input: Article: The first time we started using it, we thought it would just be a bit of fun, a one-time thing. _ A _ "Let's just give it a try," my fiancee said. I was a bit nervous, but I knew some of our friends were already into it, and they said it was fine and that I should relax because everyone was doing it."OK," I agreed, convinced it would be harmless. _ B _ Before long, we were using it once a week. Then it became twice a week. We went from using it after work to using it in the mornings, and then at lunchtime, too. Suddenly we reached a point where we were using it every day. Even when I wasn't using it, I was thinking about using it. _ C _ That's when I realized the terrible truth. We couldn't stop. Dear readers, it shames me to admit it, but I am an addict of online shopping site Taobao. And I don't think I'm the only one. _ D _ I see the telltale signs every where: People with bags under their eyes, clearly exhausted after staying up late browsing items they might one day need (but probably won't),like the 1940s leather aviator cap I bought in the event I ever need to become an aviator in the 1940s. I see co-workers furtively sneaking down to the mailroom, eyes darting around suspiciously. I know what's going through your mind as you read this. "This isn't me," you're thinking, "I can stop anytime I want." But can you? In China you can get same day delivery for just about anything you buy online. In Australia, my home country, the same item would take weeks to arrive. "It's the convenience," I said to my fiancee. "That's why we're hooked." But is that convenience worth the risk of waking up one morning to discover you've been buried alive in masses of brand new women's shoes? In my case it's probably not, especially because I suspect my fiancee won't realize I'm missing until weeks later, when my credit card stops working and I've long since expired. So what can you do to battle this terrible addiction? Never fear, dear readers, because I've created a special five-step list to help you stop online shopping. Step one: Acknowledge you have a problem. Resist buying adult-sized, Star Wars Stormtrooper outfit on Taobao. You don't really need it. Step two: Try not to feel guilty about buying adult-sized, Star Wars Stormtrooper outfit on Taobao. Step three: Put the computer and smartphone away, get back to nature, and take a walk in the park. Step four: Try not to feel guilty about buying a new outfit for your walk in the park. I mean, it was on sale, right? Step five: Buying a book on how to quit Taobao...from Taobao. On second thoughts, maybe don't listen to me, after all.
