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. After reading the above, is "Hills" the correct answer to the question "What features did the glaciers cause in Illinois?"? OPTIONS:
- no
- yes

Answer:
yes

Question:
Milwaukee, Wisconsin (CNN) -- President Barack Obama, in a bid to create jobs and boost economic growth, called on Congress on Monday to pass a $50 billion plan to renew the country's transportation infrastructure. His address was the first of two speeches the president is scheduled to make this week to frame his administration's ongoing response to the recession, less than two months ahead of midterm elections in which Democratic majorities in the House and Senate are in jeopardy. "Today, I am announcing a new plan for rebuilding and modernizing America's roads, and rails and runways for the long term," said Obama, who spoke on Labor Day in Milwaukee, Wisconsin -- a state with competitive gubernatorial and U.S. Senate races. "We used to have the best infrastructure in the world. We can have it again," he said to loud cheers from a crowd of union workers. The proposal envisions -- over a six year period -- rebuilding 150,000 miles of roads, 4,000 miles of rail and 150 miles of airport runways. It also would include modernizing the nation's air traffic control system in an effort to reduce delays and travel time. "This will not only create jobs immediately. It's also going to make our economy hum over the long haul," said the president. Obama hopes to work with Congress to enact an up-front investment of $50 billion -- an amount a White House statement said would represent a significant chunk of new spending on infrastructure. The investment would then be paired with what the administration called a framework to improve transportation spending. The long-term plan would include the establishment of an Infrastructure Bank, which would leverage federal dollars and focus on projects that could deliver the the biggest bang for the buck, Obama said. The president stressed the need for Democrats and Republicans to work together on the transportation initiative, which would need to be approved by Congress. After reading the above, is "A modernized and improved infrastructure" the correct answer to the question "What does the proposal envision?"? OPTIONS:
- no
- yes

Answer:
yes

Question:
(CNN) -- Jo-Wilfried Tsonga ended Roger Federer's hopes of winning a record-equaling seventh Wimbledon title on Wednesday as the French 12th seed staged a stunning fightback to reach the semifinals. Federer appeared to be cruising into the last four after winning the first two sets, but Tsonga inflicted the Swiss world No. 3's first defeat from that vantage point in 179 grand slam matches. It was only the third time in the 29-year-old's glittering career that the 16-time grand slam champion had surrendered a two-set lead. Tsonga, ranked 19th in the world, triumphed 3-6 6-7 (3-7) 6-4 6-4 6-4 on Centre Court, serving out to love as he earned a clash with second seed Novak Djokovic. The Serbian, who beat Tsonga in the 2008 Australian Open final, ended the dream run of Australian 18-year-old Bernard Tomic. Tsonga defeated Federer for just the second time in six meetings, their first on grass. "It was amazing. I played unbelievable. It's never easy to come back against Roger. I'm so happy, it's crazy," the 26-year-old told reporters after reaching the semifinals at Wimbledon for the first time. "He's the biggest champion in the sport. He has achieved so much and is the best player in the world. To be two sets down and come back was unbelievable. I served really well. Against Djokovic I will have to come out and do the same again." Federer has now lost in the quarterfinals two years in a row, being beaten by eventual runner-up Tomas Berdych in 2010. "Jo played great. Really from start to finish I don't remember seeing a break point after I broke him in the first game," Federer said. After reading the above, is "Novak Djokovic" the correct answer to the question "What two players beat Federer in the quarterfinals?"? OPTIONS:
- no
- yes

Answer:
yes
