In architecture Durer cites Vitruvius but elaborates his own classical designs and columns. In typography, Durer depicts the geometric construction of the Latin alphabet, relying on Italian precedent. However, his construction of the Gothic alphabet is based upon an entirely different modular system. The fourth book completes the progression of the first and second by moving to three-dimensional forms and the construction of polyhedra. Here Durer discusses the five Platonic solids, as well as seven Archimedean semi-regular solids, as well as several of his own invention. In all these, Durer shows the objects as nets. Finally, Durer discusses the Delian Problem and moves on to the 'construzione legittima', a method of depicting a cube in two dimensions through linear perspective. It was in Bologna that Durer was taught (possibly by Luca Pacioli or Bramante) the principles of linear perspective, and evidently became familiar with the 'costruzione legittima' in a written description of these principles found only, at this time, in the unpublished treatise of Piero della Francesca. He was also familiar with the 'abbreviated construction' as described by Alberti and the geometrical construction of shadows, a technique of Leonardo da Vinci. Although Durer made no innovations in these areas, he is notable as the first Northern European to treat matters of visual representation in a scientific way, and with understanding of Euclidean principles. In addition to these geometrical constructions, Durer discusses in this last book of Underweysung der Messung an assortment of mechanisms for drawing in perspective from models and provides woodcut illustrations of these methods that are often reproduced in discussions of perspective.

Question: "In which book does Durer show the understanding of Euclidean principles?"

OPTIONS:
- no
- yes

Answer: "His last book"

Response: yes

Moscow (CNN) -- Divers have completed their search of a Russian cruise ship that sank last weekend with the loss of many lives, the Emergency Situations Ministry told CNN Friday. The official death toll has reached 114 -- including 66 women, 28 children and 20 men, the ministry said. The bodies of 15 people are still missing. There were 208 people on the "Bulgaria" at the time of the accident Sunday, of whom 79 were rescued. Divers have checked all the boat's compartments, the ministry said, and are now looking for more bodies around the boat as well downstream on the Volga River, where they could have been carried by the current. The area where search efforts continue has been enlarged to 200 kilometers (125 miles) from the scene, Russian Transport Minister Igor Levitin said at a briefing Friday. Preparations are under way for the cruise ship to be raised from the river bottom in the coming days. Two large boat cranes, one from Moscow and another one from Volgograd, which will be used for the lifting, are on the way to the accident site. "We have asked the Emergency Situations Ministry to keep 23 divers at the scene to continue the search for bodies even during the lifting operation," Levitin said. Specialist military divers were brought in mid-week to aid in the search efforts. Four people face criminal charges over the sinking of the ship, which Russian media have called the most devastating river accident in the country's history.

Question: "How many had the official death toll reached?"

Problem: Ratners Group PLC, a fast-growing, acquisition-minded London-based jeweler, raised its price for Seattle-based specialty jeweler Weisfield's Inc. to $57.50 a share, or $62.1 million, from $50 a share, or $55 million, after another concern said it would be prepared to outbid Ratners's initial offer. The other concern wasn't identified. Ratners's chairman, Gerald Ratner, said the deal remains of "substantial benefit to Ratners." In London at mid-afternoon yesterday, Ratners's shares were up 2 pence (1.26 cents), at 260 pence ($1.64). The sweetened offer has acceptances from more than 50% of Weisfield's shareholders, and it is scheduled for completion by Dec. 10. The acquisition of 87-store Weisfield's raises Ratners's U.S. presence to 450 stores. About 30% of Ratners's profit already is derived from the U.S.

Question: "Was the increased share price a good or bad deal for Ratners Group PLC?"

Answer: "Good"
