question:
Roofs are traditionally constructed from Alpine rocks such as pieces of schist, gneiss or slate. Such chalets are typically found in the higher parts of the valleys, as in the Maurienne valley in Savoy, where the amount of snow during the cold months is important. The inclination of the roof cannot exceed 40%, allowing the snow to stay on top, thereby functioning as insulation from the cold. In the lower areas where the forests are widespread, wooden tiles are traditionally used. Commonly made of Norway spruce, they are called "tavaillon". The Alpine regions are multicultural and linguistically diverse. Dialects are common, and vary from valley to valley and region to region. In the Slavic Alps alone 19 dialects have been identified. Some of the French dialects spoken in the French, Swiss and Italian alps of Aosta Valley derive from Arpitan, while the southern part of the western range is related to Old Provencal; the German dialects derive from Germanic tribal languages. Romansh, spoken by two percent of the population in southeast Switzerland, is an ancient Rhaeto-Romanic language derived from Latin, remnants of ancient Celtic languages and perhaps Etruscan.
answer:
What are roofs traditionally constructed from?

question:
Pitt's Act was deemed a failure because it quickly became apparent that the boundaries between government control and the company's powers were nebulous and highly subjective. The government felt obliged to respond to humanitarian calls for better treatment of local peoples in British-occupied territories. Edmund Burke, a former East India Company shareholder and diplomat, was moved to address the situation and introduced a new Regulating Bill in 1783. The bill was defeated amid lobbying by company loyalists and accusations of nepotism in the bill's recommendations for the appointment of councillors.
answer:
The name of the Act that was a failure in creating bourdaries for the Crown and the EIC for being subjective?

question:
Until the period following World War I the Near East and the Middle East coexisted, but they were not always seen as distinct. Bertram Lenox Simpson, a colonial officer killed eventually in China, uses the terms together in his 1910 book, The Conflict of Color, as "the Near and Middle East." The total super-region consisted of "India, Afghanistan, Persia, Arabistan, Asia Minor, and last, but not least, Egypt." Simpson (under his pen-name, Weale) explains that this entire region "is politically one region in spite of the divisions into which it is academically divided." His own term revives "the Nearer East" as opposed to "the Far East."
answer:
The Near East and the Middle East coexisted until what period?
