Example 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

Example Input: Article: It was the first day of second grade, and Sarah had been looking forward to this moment. The night before, she laid out her favorite clothes: a white coat and a bright yellow shirt. When having breakfast, Sarah dropped some food on her shirt, so she had to change into her second-best clothes, blue jeans and a Jonas Brothers T-shirt. After breakfast Sarah rushed to catch the school bus and when she was just reaching the door the bus driver opened it. The door hit right in Sarah's face and blood dripped from her nose. The driver wanted to send her home, but she refused, "It is the most important day of the year! I can't miss it!" Before classes, Sarah went to her favorite swing. When rising high, she saw her best friend little Jack. She let go of the swing and waved to him with one hand. Unfortunately, she flew out of the swing and landed hard on the sand, breaking a leg and an arm. As she lay in the sand, she noticed a shiny thing on the ground beside her. With her good hand she took it. When Sarah' mother rushed into the ward she was surprised by what she saw: her girl was lying in bed with an arm and a leg in the splint , a broken nose, and blood stains on her second-best clothes. Expecting to see her child crying, she was confused when she saw a big, bright smile on Sarah's face. "Sarah, look at you!" her mother cried. "You were hurt so badly and why are you smiling?" "Look, Mommy, I found a diamond!" Sarah laughed. Life can be like that. It can be tough, even painful sometimes. But there are always treasures that make the pain worth suffering.
