In this task, you will be presented with a context passage, a question about that paragraph, and a possible answer to that question. The task is to check the validity of the answer. Answer with "Yes" or "No".

[EX Q]: You may be wondering, how can a glacier get so big? Why does it move? These are both good questions. In the winter months, precipitation falls as snow. This solid form of water builds up on the ground as long as the temperatures stay cold enough. As the temperature rises, the snow starts to melt. The frozen water changes state back into a liquid state. Nearer the poles, summer does not last very long. If the summer is long enough and warm enough, all the snow may melt. This is what typically happens now. The earth was a little cooler 12,000 years ago. As a result, during the summer months, that amount of snow did not melt. It may have only been an inch or so of snow that melted. The following winter, snow fell on top of this left-over snow. This next winters snowfall had a head start. Year after year, the snow that did not melt became thicker and thicker. Inch by inch the snow started to build up. Over many years, layer upon layer of snow compacted and turned to ice. <sep>What are two characteristics of glaciers?<sep>Big and compact
[EX A]: Yes

[EX Q]: So what is gravity? A typical definition of gravity is that it is a force. It causes an attraction between two masses. According to this definition, anything that has mass exerts a force. Any object exerts gravity on other objects. It does not matter how small it is, it has gravity. The more matter an object has, the more gravity it has. Your pencil has a tiny bit of gravity, but far too little to notice. What about a planet? It would have a lot of gravity. An objects gravity exerts a pull on other objects. Friction only occurs between objects that are touching. Gravity can act between objects that are not touching. In fact, gravity can act over very long distances. Where else can you feel gravity? <sep>How do objects interact under gravity?<sep>gravity causes an attraction between two masses
[EX A]: Yes

[EX Q]: Jack and Mackenzie wanted to do something fun during their day off from school. They knew that the library had story time on Monday, Tuesday, and Wednesday. Their mother told them they could go to the library every Tuesday for their story time. They packed up the car and drove to the library, ready for a fun morning. When they arrived to the story room, there were lots of other children their age, all sitting cross-legged and ready for the story of the day. The teacher told them they would be reading "The Wild Horse". She began to tell the story of Majestic, the wild horse who could not be calmed. His people had tried and tried to break him, but he was wild at heart. Every time they took him to the river to drink, he would run straight into the water and get soaking wet! He would splash and play until he was ready to go back home, where he would sleep for hours, having worn himself out playing. <sep>Where are Jack and Mckenzie going?<sep>To the library
[EX A]:
Yes
