Input: Consider Input: Article: Joey is loyal, encouraging and self-sacrificing, always putting others' interests ahead of his own. He is a hard worker, who also loves to run and play. In short, he's an ideal friend and a heroic character. Here is the thing: Joey is a horse, who appears as the main character in Steven Spielberg's new film War Horse. It is based on Michael Morpurgo's 1982 novel, which also caused the same-titled Tony Awards winning play. The film follows the saga of Joey, a racehorse that's trained for farm work under the loving care of Albert (Jeremy Irvine )after Albert's drunk father Ted(Peter Mullan ) overpays for the animal at auction . Then the World War I tears Albert and Joey apart. Joey is sold into the war effort for the British and starts his episodic adventures in Europe. Splendidly staged, the battle plots in the film are visually and impressive. And with Spielberg's unique, top-notch direction and storytelling skills, War Horse cannot escape its episodic nature, calling to mind another Spielberg film about the horrors of war and its effects upon soldiers and civilians--Saving Private Ryan. While that film shocked with horrific scenes of bleeding, it relied on a company of easily-described characters and a focused storyline to present heroic themes. Like Saving Private Ryan, War Horse clings to a series of characters, not only Albert, but also British officers, French civilians and German soldiers, who display courage in the face of danger. Everyone who comes in contact with Joey is either already in touch with their inner angel or is quickly moved to become more humane. Although none of this covers the fact that we've seen this stuff elsewhere before, the lovely sentiment will steal your heart. And the emotional signature of Spielberg can be felt as he establishes the relationship between the boy and the horse and the mood of the piece - there will be tears. Therefore, calling this beautiful, dramatically incomplete film " Saving Private Joey", is entirely justifiable. 
 Answer: tells the story happening in the Second World War

Output: In common with " Saving Private Ryan", the film  War Horse    _    .


Input: Consider Input: Article: Our first winter in Canada was the happiest we have experienced. We were living in the countryside then and had just arrived from Hong Kong that autumn. One evening in mid December snow began to fall. When we looked out of the window and saw that it was snowing, we all cheered. It was the first snow we had ever seen and we were excited. We could hardly wait for the snow to stop so that we could go out to play. Next morning when we woke up, it was still snowing. We switched on the radio and learned that more than ten inches of snow had falled during the night and that since the roads were blocked there would be no school that day. We jumped up and down for joy and begged mother to let us go outside to play in the snow. She said we could go out after breakfast if we dressed ourselves warmly and promised to come back as soon as we felt cold. When we went out, the snow had almost stopped. The roads , paths, gardens, and playing grounds were all hidden under a white blanket of soft snow. It was the most beautiful sight we had ever seen. Just then, we saw some neighbour's children coming out to play. We ran over to join them. Together we built a snowman and a snow house. After that, we took turns sliding down a hill on a large piece of cardboard. We were having so much fun when supper time came. Mother almost had to force us to go in and eat. 
 Answer: it was the first time they had seen snow

Output: The children all cheered when they saw the snow because   _  .


Input: Consider Input: Article: California places limits on water use to deal with the state's four-year drought. Californians are feeling the heat after Governor Jerry Brown announced an order that puts mandatory  statewide water cutbacks into effect. California has faced water-use cutbacks in the past. In January 2014, Governor Brown called for residents to curb their water use by 20 percent, but many places around the state failed to meet that goal. This most recent announcement, however, marks the first time in the state's history that mandatory restrictions have been ordered. Most of California's water supply comes from the Sierra Nevada mountain range snowpack. Normally, during the spring and summer, this snow melts and puts new supplies into groundwater. but this past winter, the snowpack reached its lowest point since 1950. "today we are standing on dry grass where there should be feet of snow" announced Governor Brown. As part of his order, Governor Brown called upon the state Water Resource Control Board to draft emergency rules for water use in the coming month. Cities and towns across the state must cut water usage by 25 percent. If city water agencies fail to meet these targets for water conservation, they could be fined $10,000 a day. The state will also support local governments in replacing 50 million square feet of lawns with drought-tolerant plants that use less water. Outdoor lawn watering will be limited to two days per week, and residents will not be permitted to water their lawns during rainstorms and for two days afterwards. The order also asks local water agencies to raise the price of water to discourage excessive water use. Governor Brown said change may not be easy, but it's necessary to ensure that residents can fill their water glasses into the future. "it is a wake-up call," he said. "it's requiring action and changes in behavior." 
 Answer: Its residents' excessive water use.


Output: This year's drought in California is mainly caused by_.
