Question: Although it is said that the "dog is man's best friend" regarding 1724% of dogs in the developed countries, in the developing world they are feral, village or community dogs, with pet dogs uncommon. These live their lives as scavengers and have never been owned by humans, with one study showing their most common response when approached by strangers was to run away (52%) or respond with aggression (11%). We know little about these dogs, nor about the dogs that live in developed countries that are feral, stray or are in shelters, yet the great majority of modern research on dog cognition has focused on pet dogs living in human homes.
Is there an answer to this question: When these feral dogs are approached by a person, they tend to do this 52% of the time?

Answer: run away

Question: Political and economic relations were drastically influenced by these theories as the concept of the guild was subordinated to the theory of free trade, and Roman Catholic dominance of theology was increasingly challenged by Protestant churches subordinate to each nation-state, which also (in a fashion the Roman Catholic Church often decried angrily) preached in the vulgar or native language of each region. However, the enlightenment was an outright attack on religion, particularly Christianity. The most outspoken critic of the church in France was Francois Marie Arouet de Voltaire, a representative figure of the enlightenment. After Voltaire, religion would never be the same again in France.
Is there an answer to this question: The enlightenment was an outright attack on what?

Answer: religion

Question: General Frossard's II Corps and Marshal Bazaine's III Corps crossed the German border on 2 August, and began to force the Prussian 40th Regiment of the 16th Infantry Division from the town of Saarbrucken with a series of direct attacks. The Chassepot rifle proved its worth against the Dreyse rifle, with French riflemen regularly outdistancing their Prussian counterparts in the skirmishing around Saarbrucken. However the Prussians resisted strongly, and the French suffered 86 casualties to the Prussian 83 casualties. Saarbrucken also proved to be a major obstacle in terms of logistics. Only one railway there led to the German hinterland but could be easily defended by a single force, and the only river systems in the region ran along the border instead of inland. While the French hailed the invasion as the first step towards the Rhineland and later Berlin, General Le Buf and Napoleon III were receiving alarming reports from foreign news sources of Prussian and Bavarian armies massing to the southeast in addition to the forces to the north and northeast.
Is there an answer to this question: What proved its worth against the Dreyse rifle?

Answer:
The Chassepot rifle
