Passage: During the Franco-Prussian War and the Siege of Strasbourg, the city was heavily bombarded by the Prussian army. The bombardment of the city was meant to break the morale of the people of Strasbourg. On 24 and 26 August 1870, the Museum of Fine Arts was destroyed by fire, as was the Municipal Library housed in the Gothic former Dominican church, with its unique collection of medieval manuscripts (most famously the Hortus deliciarum), rare Renaissance books, archeological finds and historical artifacts. The gothic cathedral was damaged as well as the medieval church of Temple Neuf, the theatre, the city hall, the court of justice and many houses. At the end of the siege 10,000 inhabitants were left without shelter; over 600 died, including 261 civilians, and 3200 were injured, including 1,100 civilians. Question: Who bombarded the city of Strasbourg?
answer:
Prussian army

question:
Passage: The softness of copper partly explains its high electrical conductivity (59.6106 S/m) and thus also high thermal conductivity, which are the second highest (to silver) among pure metals at room temperature. This is because the resistivity to electron transport in metals at room temperature mostly originates from scattering of electrons on thermal vibrations of the lattice, which are relatively weak for a soft metal. The maximum permissible current density of copper in open air is approximately 3.1106 A/m2 of cross-sectional area, above which it begins to heat excessively. As with other metals, if copper is placed against another metal, galvanic corrosion will occur. Question: What is the explanation for copper's capacity for electrical conductivity?
answer:
The softness

question:
Passage: There are as many as 22 public beaches (most beaches on St Barthelemy are known as "Anse de..." etc. ) of which 15 are considered suitable for swimming. They are categorized and divided into two groups, the leeward side (calm waters protected by the island itself) and windward side (some of which are protected by hills and reefs). The windward beaches are popular for windsurfing. The beach of St Jean is suitable for water sports and facilities have been created for that purpose. The long beach at Lorient has shade and is a quiet beach as compared to St. Jean. Question: How many public beaches are there in St. Barts?
answer:
22
