Problem: A residential elevator is often permitted to be of lower cost and complexity than full commercial elevators. They may have unique design characteristics suited for home furnishings, such as hinged wooden shaft-access doors rather than the typical metal sliding doors of commercial elevators. Construction may be less robust than in commercial designs with shorter maintenance periods, but safety systems such as locks on shaft access doors, fall arrestors, and emergency phones must still be present in the event of malfunction.
What type of elevators are generally less costly than full commercial elevators?
The answer is the following: residential

Problem: It is thought that annelids were originally animals with two separate sexes, which released ova and sperm into the water via their nephridia. The fertilized eggs develop into trochophore larvae, which live as plankton. Later they sink to the sea-floor and metamorphose into miniature adults: the part of the trochophore between the apical tuft and the prototroch becomes the prostomium (head); a small area round the trochophore's anus becomes the pygidium (tail-piece); a narrow band immediately in front of that becomes the growth zone that produces new segments; and the rest of the trochophore becomes the peristomium (the segment that contains the mouth).
What do annelids' larvae live like?
The answer is the following: plankton

Problem: Just days before the relay supporters of Falun Gong demonstrated in front of the Chinese embassy in the Malaysian capital. As many as 1,000 personnel from the special police unit were expected to be deployed on the day of the relay. A Japanese family with Malaysian citizenship and their 5-year-old child who unfurled a Tibetan flag were hit by a group of Chinese nationals with plastic air-filled batons and heckled by a crowd of Chinese citizens during the confrontation at Independence Square where the relay began, and the Chinese group shouted: "Taiwan and Tibet belong to China." Later during the day, the Chinese volunteers forcefully took away placards from two other Malaysians protesting at the relay. One of the protesting Malaysian was hit in the head.
What did Chinese volunteers take from two Malaysian demonstrators?
The answer is the following: placards

Problem: Another point of interest is the Old Town. In the centre are the large Marktkirche (Church St. Georgii et Jacobi, preaching venue of the bishop of the Lutheran Landeskirche Hannovers) and the Old Town Hall. Nearby are the Leibniz House, the Nolte House, and the Beguine Tower. A very nice quarter of the Old Town is the Kreuz-Church-Quarter around the Kreuz Church with many nice little lanes. Nearby is the old royal sports hall, now called the Ballhof theatre. On the edge of the Old Town are the Market Hall, the Leine Palace, and the ruin of the Aegidien Church which is now a monument to the victims of war and violence. Through the Marstall Gate you arrive at the bank of the river Leine, where the world-famous Nanas of Niki de Saint-Phalle are located. They are part of the Mile of Sculptures, which starts from Trammplatz, leads along the river bank, crosses Königsworther Square, and ends at the entrance of the Georgengarten. Near the Old Town is the district of Calenberger Neustadt where the Catholic Basilica Minor of St. Clemens, the Reformed Church and the Lutheran Neustädter Hof- und Stadtkirche St. Johannis are located.
What is the name of the momument to the victims of war and violence?
The answer is the following:
Aegidien Church
