Question: Equivalently, the smallness of the Planck constant reflects the fact that everyday objects and systems are made of a large number of particles. For example, green light with a wavelength of 555 nanometres (the approximate wavelength to which human eyes are most sensitive) has a frequency of 7014540000000000000♠540 THz (7014540000000000000♠540×1012 Hz). Each photon has an energy E = hf = 6981358000000000000♠3.58×10−19 J. That is a very small amount of energy in terms of everyday experience, but everyday experience is not concerned with individual photons any more than with individual atoms or molecules. An amount of light compatible with everyday experience is the energy of one mole of photons; its energy can be computed by multiplying the photon energy by the Avogadro constant, NA ≈ 7023602200000000000♠6.022×1023 mol−1. The result is that green light of wavelength 555 nm has an energy of 7005216000000000000♠216 kJ/mol, a typical energy of everyday life.

Answer: the fact that everyday objects and systems are made of a large number of particles
Question: France's major upscale department stores are Galeries Lafayette and Le Printemps, which both have flagship stores on Boulevard Haussmann in Paris and branches around the country. The first department store in France, Le Bon Marché in Paris, was founded in 1852 and is now owned by the luxury goods conglomerate LVMH. La Samaritaine, another upscale department store also owned by LVMH, closed in 2005. Mid-range department stores chains also exist in France such as the BHV (Bazar de l'Hotel de Ville), part of the same group as Galeries Lafayette.
Try to answer this question if possible: Who currently owns Le Bon Marche?
Answer: LVMH
Question: Athanasius knew Greek and admitted not knowing Hebrew [see, e.g., the 39th Festal Letter of St. Athan.]. The Old Testament passages he quotes frequently come from the Septuagint Greek translation. Only rarely did he use other Greek versions (to Aquila once in the Ecthesis, to other versions once or twice on the Psalms), and his knowledge of the Old Testament was limited to the Septuagint. Nonetheless, during his later exile, with no access to a copy of the Scriptures, Athanasius could quote from memory every verse in the Old Testament with a supposed reference to the Trinity without missing any.[citation needed] The combination of Scriptural study and of Greek learning was characteristic of the famous Alexandrian School.
Try to answer this question if possible: Did he understand Hebrew?
Answer: not knowing Hebrew
Question: As of 2012, renewable energy plays a major role in the energy mix of many countries globally. Renewables are becoming increasingly economic in both developing and developed countries. Prices for renewable energy technologies, primarily wind power and solar power, continued to drop, making renewables competitive with conventional energy sources. Without a level playing field, however, high market penetration of renewables is still dependent on a robust promotional policies. Fossil fuel subsidies, which are far higher than those for renewable energy, remain in place and quickly need to be phased out.
