Question: Solar cookers use sunlight for cooking, drying and pasteurization. They can be grouped into three broad categories: box cookers, panel cookers and reflector cookers. The simplest solar cooker is the box cooker first built by Horace de Saussure in 1767. A basic box cooker consists of an insulated container with a transparent lid. It can be used effectively with partially overcast skies and will typically reach temperatures of 90150 C (194302 F). Panel cookers use a reflective panel to direct sunlight onto an insulated container and reach temperatures comparable to box cookers. Reflector cookers use various concentrating geometries (dish, trough, Fresnel mirrors) to focus light on a cooking container. These cookers reach temperatures of 315 C (599 F) and above but require direct light to function properly and must be repositioned to track the Sun.
Try to answer this question if possible: Reflector cookers can reach temperatures in Celsius of up to what?
Answer: 315
Question: The task of organizing the U.S. Army commenced in 1775. In the first one hundred years of its existence, the United States Army was maintained as a small peacetime force to man permanent forts and perform other non-wartime duties such as engineering and construction works. During times of war, the U.S. Army was augmented by the much larger United States Volunteers which were raised independently by various state governments. States also maintained full-time militias which could also be called into the service of the army.

Question: With his mazurkas and polonaises, Chopin has been credited with introducing to music a new sense of nationalism. Schumann, in his 1836 review of the piano concertos, highlighted the composer's strong feelings for his native Poland, writing that "Now that the Poles are in deep mourning [after the failure of the November 1830 rising], their appeal to us artists is even stronger ... If the mighty autocrat in the north [i.e. Nicholas I of Russia] could know that in Chopin's works, in the simple strains of his mazurkas, there lurks a dangerous enemy, he would place a ban on his music. Chopin's works are cannon buried in flowers!" The biography of Chopin published in 1863 under the name of Franz Liszt (but probably written by Carolyne zu Sayn-Wittgenstein) claims that Chopin "must be ranked first among the first musicians ... individualizing in themselves the poetic sense of an entire nation."

Answer: sense of nationalism
Question: Napoleon could be considered one of the founders of modern Germany. After dissolving the Holy Roman Empire, he reduced the number of German states from 300 to less than 50, paving the way to German Unification. A byproduct of the French occupation was a strong development in German nationalism. Napoleon also significantly aided the United States when he agreed to sell the territory of Louisiana for 15 million dollars during the presidency of Thomas Jefferson. That territory almost doubled the size of the United States, adding the equivalent of 13 states to the Union.

Answer:
the Holy Roman Empire
