Question: A new delimitation of the federal territory keeps being debated in Germany, though "Some scholars note that there are significant differences among the American states and regional governments in other federations without serious calls for territorial changes ...", as political scientist Arthur B. Gunlicks remarks. He summarizes the main arguments for boundary reform in Germany: "... the German system of dual federalism requires strong Lander that have the administrative and fiscal capacity to implement legislation and pay for it from own source revenues. Too many Lander also make coordination among them and with the federation more complicated ...". But several proposals have failed so far; territorial reform remains a controversial topic in German politics and public perception.
Try to answer this question if possible: What is one argument for increasing the number of Lander?
Answer: unanswerable
Question: At present, plans are being considered for building a new dual carriageway west of Strasbourg, which would reduce the buildup of traffic in that area by picking up north and southbound vehicles and getting rid of the buildup outside Strasbourg. The line plans to link up the interchange of Hrdt to the north of Strasbourg, with Innenheim in the southwest. The opening is envisaged at the end of 2011, with an average usage of 41,000 vehicles a day. Estimates of the French Works Commissioner however, raised some doubts over the interest of such a project, since it would pick up only about 10% of the traffic of the A35 at Strasbourg. Paradoxically, this reversed the situation of the 1950s. At that time, the French trunk road left of the Rhine not been built, so that traffic would cross into Germany to use the Karlsruhe-Basel Autobahn.

Question: Some rock formations in the path of a glacier are sculpted into small hills called roche moutonnee, or "sheepback" rock. Roche moutonnee are elongated, rounded, and asymmetrical bedrock knobs that can be produced by glacier erosion. They range in length from less than a meter to several hundred meters long. Roche moutonnee have a gentle slope on their up-glacier sides and a steep to vertical face on their down-glacier sides. The glacier abrades the smooth slope on the upstream side as it flows along, but tears loose and carries away rock from the downstream side via plucking.
Try to answer this question if possible: What is smooth on the downstream side?
Answer: unanswerable
Question: A solar balloon is a black balloon that is filled with ordinary air. As sunlight shines on the balloon, the air inside is heated and expands causing an upward buoyancy force, much like an artificially heated hot air balloon. Some solar balloons are large enough for human flight, but usage is generally limited to the toy market as the surface-area to payload-weight ratio is relatively high.
Try to answer this question if possible: What happens when sunlight shines on a solar balloon?
Answer:
the air inside is heated and expands causing an upward buoyancy force
