Example Input: You know that friction also causes heat. Think about when you rub your hands together. It is friction that makes them warm. But why does this happen? Friction causes the molecules on rubbing surfaces to move faster. Faster moving particles have more heat energy. Heat from friction can be useful. Can you think of other places where you might find friction? Friction also lets you light a match. Heat from friction can also cause problems. It can cause a car to overheat. To reduce friction, oil is added to the engine. Oil coats the surfaces of moving parts. This coating of oil makes them slippery. When things are slippery there is less friction. Have you ever seen a sign that says, slippery when wet? This too has to do with friction. Water, like oil, can reduce friction. The wet surface may allow your shoes to slide more easily. <sep>What can be done to prevent friction problems in engines?<sep>Oil is added to the engine
Example Output: Yes

Example Input: 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. <sep>Who were many of the people happy about what the president was saying in his speech about renewing the country's transportation infrastructure?<sep>Republicans
Example Output: No

Example Input: A government-sponsored coup last year made Bruce Iwasaki and Neal Dudovitz the kings of Los Angeles County's federally funded legal aid community. The two men emerged atop a changed landscape that resulted from a decade of begging for a share of shrinking public dollars doled out by an unsympathetic GOP-controlled Congress. That era was capped in 1998, when the Legal Services Corp. forced 275 legal aid providers nationwide to combine into 179. To comply with the orders from their main funding source, a new species of poverty lawyer emerged - a tech-savvy and button-down breed who swapped neighborhood walkin offices for toll-free phone lines, self-help kiosks and Internet access to legal advice. While some organizations made the dramatic change look effortless, for others, it did not come easy. And few programs provide more dramatic illustrations of the promise and pitfalls of government-funded legal services than Los Angeles County's two largest providers of federally funded services - Legal Aid Foundation of Los Angeles and Pacoima-based Neighborhood Legal Services of Los Angeles County. From his offices in Koreatown, Iwasaki, a soft-spoken former O'Melveny & Myers attorney, quietly engineered a merger between a much smaller Legal Aid Society of Long Beach and his program, the Legal Aid Foundation of Los Angeles. The merger was completed peacefully within a year of the federal order. Today, the programs operate seamlessly, offering new innovations - including toll-free multilingual phone advisers, expanded hours for domestic-violence clinics, and renewed immigration and consumer aid - built on the foundations of the old program. The organization is Los Angeles' largest government-funded group, with a budget of $11 million leveraged into $40 million in legal services to the poor. <sep>What was the result of the merger?<sep>Less funding
