Other buildings of its kind are the "Hôtel de Hanau" (1736, now the city hall), the Hôtel de Klinglin (1736, now residence of the préfet), the Hôtel des Deux-Ponts (1755, now residence of the military governor), the Hôtel d'Andlau-Klinglin (1725, now seat of the administration of the Port autonome de Strasbourg) etc. The largest baroque building of Strasbourg though is the 150 m (490 ft) long 1720s main building of the Hôpital civil. As for French Neo-classicism, it is the Opera House on Place Broglie that most prestigiously represents this style.
What is the largest baroque building in Strasbourg?

Problem: The most dense rail network in Europe of 5,063 km (3,146 mi) carries over 350 million passengers annually. In 2007, each Swiss citizen travelled on average 2,258 km (1,403 mi) by rail, which makes them the keenest rail users. The network is administered mainly by the Federal Railways, except in Graubünden, where the 366 km (227 mi) narrow gauge railway is operated by the Rhaetian Railways and includes some World Heritage lines. The building of new railway base tunnels through the Alps is under way to reduce the time of travel between north and south through the AlpTransit project.
Who mainly administers the Swiss railway system?
The answer is the following: Federal Railways

Problem: Many adult insects use six legs for walking and have adopted a tripedal gait. The tripedal gait allows for rapid walking while always having a stable stance and has been studied extensively in cockroaches. The legs are used in alternate triangles touching the ground. For the first step, the middle right leg and the front and rear left legs are in contact with the ground and move the insect forward, while the front and rear right leg and the middle left leg are lifted and moved forward to a new position. When they touch the ground to form a new stable triangle the other legs can be lifted and brought forward in turn and so on. The purest form of the tripedal gait is seen in insects moving at high speeds. However, this type of locomotion is not rigid and insects can adapt a variety of gaits. For example, when moving slowly, turning, or avoiding obstacles, four or more feet may be touching the ground. Insects can also adapt their gait to cope with the loss of one or more limbs.
Most adult insects have adopted what kind of gait?
The answer is the following:
tripedal
