Input: Consider Input: Article: A dog who chewed off his owner's infected toe while he was passed-out drunk has been called a lifesaver. Jerry Douthett had been out drinking when his dog Kiko bit off a large part if his big toe. His wife, Rosee, rushed him to hospital where tests showed the 48-year-old musician had dangerous high blood-sugar levels. Doctors told him his toe would have had to be cut off anyway. Mr Douthett said he had refused to get medical advice despite his toe being swollen for months. "I was hiding it from people, Rosee included," he said. "It smelled , and I look back now and realize every time we'd visit someone with a dog, their dog would smell all over my foot." The night before Mr Douthett had agreed to see a doctor, he passed out at home after going out drinking. He said, "I woke up and the dog was lying along side by foot. I said, 'Ah, there's blood everywhere.' I ran to the bathroom and started to scream." However, he believes Kiko could sense the disease coming from his big toe. "He's a hero," Mr Douthett said. "It wasn't an aggressive attack. He just ate the infection. He saved my life. He ate it. I mean, he must have eaten it, because we couldn't find it anywhere else in the house. I look down. There's blood all over, and my toe is gone." Before the operation, Mr Douthett asked a nurse, "Is there any chance I can get whatever's left of my toe, so I can give it to Kiko as a treat?" Kiko is still with the family but is under observation by authorities.
Answer: he was unwilling to let others know about his disease

Output: .Mr Douthett didn't want to get medical treatment because _ .

Input: Consider Input: Article: To prevent the deserts coming near, China has planted billions of trees---to replace destroyed forests and as barriers against the sand. This isn't a cure, though, say experts, as thirsty trees can make the problem worse by taking in groundwater. "Planting tress is one way, but it isn't that simple. It doesn't solve the basic issue of water resources," says Wu Bo, a professor. "We need to calculate how much water the trees will absorb, or else it could have a negative effect." Villagers in Zhengxin have taken on this challenge, with limited success. When the irrigation channels began to run dry, Lu Xianglin switched from wheat to cotton on his land. He also planted trees to protect his fields from sandstorms. He says he still gets good yields using flood irrigation and earns a good income for his family. Other farmers haven't stuck it out : about one in three have left Zhengxin in the past 10 years after their wheat crops died. Young people who can find jobs in the towns rarely return. Last week, Mr Lu joined the other men in his village on a government-arranged trip to see the land that has been set aside for their relocation, nearly 40 miles to the south. The next day, he was back, shaking his head at the plan. The idea of uprooting his family troubles him, as does the idea of giving up the land that fed his forefathers. He prefers to stay and keep up the fight. "With enough water, this problem can be solved," Lu says. "We can plant trees and grass, and they will grow bigger. That will stop the desert." Experts say that farmers could switch to drip irrigation to lessen their water intake for growing crops. Elsewhere in the region, farmers have built brick greenhouses as part of a plan to grow vegetables using less water. Roadside signs urge farmers to "Save Water, Protect the Environment".
Answer: it can make groundwater become less

Output: The negative effect of planting trees in deserts is that _ .

Input: Consider Input: Article: Every day I go into the same coffee shop on the way to work. It's part of a large chain here in the UK. I am new to the anonymous act of kindness concept. I came across it recently. A few weeks ago I worked up the courage to ask the barista if I could pay for a coffee for someone later that day. He looked at me kind of strangely and said "okay" and then put the money into the drawer where some change was put. I walked out feeling doubtful whether this would happen and privately thinking he might just add the money to his tips. This chain stamps a card every time you buy a coffee and when you get 9 stamps, the 10th coffee is free. I had just completed my card today and was due a free cup of coffee next time, so I cheered up as I headed out of the coffee shop. I believe that giving the card to people on the street is better than giving them cash so I forgot about the barista and passed the card on to a homeless guy I met later. A week later I was in the same store and I ordered my usual coffee and a new barista said to me, "Your coffee is on us." I was surprised and asked why he would give me a free coffee. He said that the staff were allowed to give out one free coffee a day to anyone they chose. And that today I was the lucky one. He said they knew that I was a regular and that I was always so cheerful with the staff. By the way, I was not sure I had been the first lucky person in the morning! This put a big smile on my face but I decided to ask if I could choose to pay it forward to someone else instead. Finally, he gave me the power to make a decision.
