Question: Imagine you are standing in a farm field in central Illinois. The land is so flat you can see for miles and miles. On a clear day, you might see a grain silo 20 miles away. You might think to yourself, it sure is flat around here. If you drive one hundred miles to the south, the landscape changes. In southern Illinois, there are rolling hills. Why do you think this is? What could have caused these features? There are no big rivers that may have eroded and deposited this material. The ground is capable of supporting grass and trees, so wind erosion would not explain it. To answer the question, you need to go back 12,000 years. Around 12,000 years ago, a giant ice sheet covered much of the Midwest United States. Springfield, Illinois, was covered by over a mile of ice. Its hard to imagine a mile thick sheet of ice. The massive ice sheet, called a glacier, caused the features on the land you see today. Where did glaciers go? Where can you see them today? Glaciers are masses of flowing ice. <sep>What couldn't the erosion have been caused by?<sep>Wind

Answer: Yes


Question: Jake was walking to the park to play baseball with his friends. He loved being outside on sunny days, and now that school was over for the year, he was playing baseball every day. The more he played, the better he got. Only Frank was better than he was. He liked playing third base, but he often played in the field. He was carrying his favorite mitt that his Grandfather had bought him. His Grandfather had taught him to catch. He loved spending time with him when he was younger, but he had moved last year. Now he only saw his Grandfather in the summer. Jake was really excited to show him his skills when he came to their next game. He could throw really fast now. He was sure his Grandfather would want to sit in the front to watch him. He knew he would jump up and down. Jake happily ran the rest of the way to the park thinking about how much fun he was going to have playing baseball this year. <sep>Did jake walk to the park everyday to play baseball with his friends during school days?<sep>No
