One boarding house, College, is reserved for seventy King's Scholars, who attend Eton on scholarships provided by the original foundation and awarded by examination each year; King's Scholars pay up to 90% of full fees, depending on their means. Of the other pupils, up to a third receive some kind of bursary or scholarship. The name "King's Scholars" is because the school was founded by King Henry VI in 1440. The original School consisted of the seventy Scholars (together with some Commensals) and the Scholars were educated and boarded at the foundation's expense.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many regular students at Eton receive a scholarship but not a bursary?
Ah, so.. unanswerable

Some bacteria produce intracellular nutrient storage granules for later use, such as glycogen, polyphosphate, sulfur or polyhydroxyalkanoates. Certain bacterial species, such as the photosynthetic Cyanobacteria, produce internal gas vesicles, which they use to regulate their buoyancy – allowing them to move up or down into water layers with different light intensities and nutrient levels. Intracellular membranes called chromatophores are also found in membranes of phototrophic bacteria. Used primarily for photosynthesis, they contain bacteriochlorophyll pigments and carotenoids. An early idea was that bacteria might contain membrane folds termed mesosomes, but these were later shown to be artifacts produced by the chemicals used to prepare the cells for electron microscopy. Inclusions are considered to be nonliving components of the cell that do not possess metabolic activity and are not bounded by membranes. The most common inclusions are glycogen, lipid droplets, crystals, and pigments. Volutin granules are cytoplasmic inclusions of complexed inorganic polyphosphate. These granules are called metachromatic granules due to their displaying the metachromatic effect; they appear red or blue when stained with the blue dyes methylene blue or toluidine blue. Gas vacuoles, which are freely permeable to gas, are membrane-bound vesicles present in some species of Cyanobacteria. They allow the bacteria to control their buoyancy. Microcompartments are widespread, membrane-bound organelles that are made of a protein shell that surrounds and encloses various enzymes. Carboxysomes are bacterial microcompartments that contain enzymes involved in carbon fixation. Magnetosomes are bacterial microcompartments, present in magnetotactic bacteria, that contain magnetic crystals.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How does gas vesicles produced by Cyanobacteria help her to move in water?
Ah, so.. move up or down into water layers with different light intensities

In contrast, Europe has a greater history of unitary states than North America, thus European "federalism" argues for a weaker central government, relative to a unitary state. The modern American usage of the word is much closer to the European sense. As the power of the Federal government has increased, some people have perceived a much more unitary state than they believe the Founding Fathers intended. Most people politically advocating "federalism" in the United States argue in favor of limiting the powers of the federal government, especially the judiciary (see Federalist Society, New Federalism).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What does federalism mean in Europe? 
Ah, so..
weaker central government, relative to a unitary state
