Context and question: The governments of Australia and New Zealand responded to the 2011 fresh-water crisis by supplying temporary desalination plants, and assisted in the repair of the existing desalination unit that was donated by Japan in 2006. In response to the 2011 drought, Japan funded the purchase of a 100 m3/d desalination plant and two portable 10 m3/d plants as part of its Pacific Environment Community (PEC) program. Aid programs from the European Union and Australia also provided water tanks as part of the longer term solution for the storage of available fresh water.
What type of device did Australia and New Zealand offer to Tuvalu during the 2011 drought?
Answer: desalination plants
Context and question: With the new stadium, Barcelona participated in the inaugural version of the Pyrenees Cup, which, at the time, consisted of the best teams of Languedoc, Midi and Aquitaine (Southern France), the Basque Country and Catalonia; all were former members of the Marca Hispanica region. The contest was the most prestigious in that era. From the inaugural year in 1910 to 1913, Barcelona won the competition four consecutive times. Carles Comamala played an integral part of the four-time champion, managing the side along with Amechazurra and Jack Greenwell. The latter became the club's first full-time coach in 1917. The last edition was held in 1914 in the city of Barcelona, which local rivals Espanyol won.
How many times did Barcelona win the Pyrenees Cup?
Answer: four
Context and question: It would appear that living organisms are remarkably inefficient (in the physical sense) in their use of the energy they receive (chemical energy or radiation), and it is true that most real machines manage higher efficiencies. In growing organisms the energy that is converted to heat serves a vital purpose, as it allows the organism tissue to be highly ordered with regard to the molecules it is built from. The second law of thermodynamics states that energy (and matter) tends to become more evenly spread out across the universe: to concentrate energy (or matter) in one specific place, it is necessary to spread out a greater amount of energy (as heat) across the remainder of the universe ("the surroundings").[note 3] Simpler organisms can achieve higher energy efficiencies than more complex ones, but the complex organisms can occupy ecological niches that are not available to their simpler brethren. The conversion of a portion of the chemical energy to heat at each step in a metabolic pathway is the physical reason behind the pyramid of biomass observed in ecology: to take just the first step in the food chain, of the estimated 124.7 Pg/a of carbon that is fixed by photosynthesis, 64.3 Pg/a (52%) are used for the metabolism of green plants, i.e. reconverted into carbon dioxide and heat.
Where is the hypothetical reason behind the pyramid of biomass observed?
