Please answer this: Extract the answer to the question from the following context. Question: How is liu written? Context: Examples are he "river", hu "lake", liu "stream", chong "riptide" (or "flush"), hua "slippery". All these characters have on the left a radical of three short strokes (), which is a reduced form of the character shui meaning "water", indicating that the character has a semantic connection with water. The right-hand side in each case is a phonetic indicator. For example, in the case of chong (Old Chinese *-lju), the phonetic indicator is zhong (Old Chinese *k-lju), which by itself means "middle". In this case it can be seen that the pronunciation of the character is slightly different from that of its phonetic indicator; the process of historical phonetic change means that the composition of such characters can sometimes seem arbitrary today.

As a share of total investment in power plants, wind and solar PV grew from 14% in 2000 to over 60% in 2012.

Please answer this: Extract the answer to the question from the following context. Question: What was being protested by the Alsatians in the storming of the city hall? Context: The year 1789 brought the French Revolution and with it the first division of Alsace into the departements of Haut- and Bas-Rhin. Alsatians played an active role in the French Revolution. On 21 July 1789, after receiving news of the Storming of the Bastille in Paris, a crowd of people stormed the Strasbourg city hall, forcing the city administrators to flee and putting symbolically an end to the feudal system in Alsace. In 1792, Rouget de Lisle composed in Strasbourg the Revolutionary marching song "La Marseillaise" (as Marching song for the Army of the Rhine), which later became the anthem of France. "La Marseillaise" was played for the first time in April of that year in front of the mayor of Strasbourg Philippe-Frederic de Dietrich. Some of the most famous generals of the French Revolution also came from Alsace, notably Kellermann, the victor of Valmy, Kleber, who led the armies of the French Republic in Vendee and Westermann, who also fought in the Vendee.
