Question: Reverse osmosis (R/O) desalination units supplement rainwater harvesting on Funafuti. The 65 m3 desalination plant operates at a real production level of around 40 m3 per day. R/O water is only intended to be produced when storage falls below 30%, however demand to replenish household storage supplies with tanker-delivered water means that the R/O desalination units are continually operating. Water is delivered at a cost of A$3.50 per m3. Cost of production and delivery has been estimated at A$6 per m3, with the difference subsidised by the government.
Try to answer this question if possible: At what storage point is R/O water production meant to be used?
Answer: below 30%
Question: A hunter-gatherer is a human living in a society in which most or all food is obtained by foraging (collecting wild plants and pursuing wild animals), in contrast to agricultural societies, which rely mainly on domesticated species.

Question: There are four categories of terra nullius, land that is unclaimed by any state: the small unclaimed territory of Bir Tawil between Egypt and Sudan, Antarctica, the oceans, and celestial bodies such as the Moon or Mars. In the last three of these, international treaties (the Antarctic Treaty, the United Nations Convention on the Law of the Sea, and the Outer Space Treaty respectively) prevent colonization and potential statehood of any of these uninhabited (and, given current technology, not permanently inhabitable) territories.
Try to answer this question if possible: What are the four categories of terra nullius?
Answer: the small unclaimed territory of Bir Tawil between Egypt and Sudan, Antarctica, the oceans, and celestial bodies
Question: However, the classification of madaris as "universities" is disputed on the question of understanding of each institution on its own terms. In madaris, the ijazahs were only issued in one field, the Islamic religious law of shariah, and in no other field of learning. Other academic subjects, including the natural sciences, philosophy and literary studies, were only treated "ancillary" to the study of the Sharia. For example, a natural science like astronomy was only studied (if at all) to supply religious needs, like the time for prayer. This is why Ptolemaic astronomy was considered adequate, and is still taught in some modern day madaris. The Islamic law undergraduate degree from al-Azhar, the most prestigious madrasa, was traditionally granted without final examinations, but on the basis of the students' attentive attendance to courses. In contrast to the medieval doctorate which was granted by the collective authority of the faculty, the Islamic degree was not granted by the teacher to the pupil based on any formal criteria, but remained a "personal matter, the sole prerogative of the person bestowing it; no one could force him to give one".
Try to answer this question if possible: What was the purpose of not studying natural sciences in madaris?
