Question: The first half of the 14th century saw much important scientific work being done, largely within the framework of scholastic commentaries on Aristotle's scientific writings. William of Ockham introduced the principle of parsimony: natural philosophers should not postulate unnecessary entities, so that motion is not a distinct thing but is only the moving object and an intermediary "sensible species" is not needed to transmit an image of an object to the eye. Scholars such as Jean Buridan and Nicole Oresme started to reinterpret elements of Aristotle's mechanics. In particular, Buridan developed the theory that impetus was the cause of the motion of projectiles, which was a first step towards the modern concept of inertia. The Oxford Calculators began to mathematically analyze the kinematics of motion, making this analysis without considering the causes of motion.
Try to answer this question if possible: What theory did impetus pave the way for?
Answer: inertia
Question: Due to the work nature of airline pilots, who often cross several timezones and regions of sunlight and darkness in one day, and spend many hours awake both day and night, they are often unable to maintain sleep patterns that correspond to the natural human circadian rhythm; this situation can easily lead to fatigue. The NTSB cites this as contributing to many accidents[unreliable medical source?] and has conducted several research studies in order to find methods of combating fatigue in pilots.
Try to answer this question if possible: Who follows a very natural human circadian rhythem?
Answer: unanswerable
Question: Animals are also involved in the distribution of seeds. Fruit, which is formed by the enlargement of flower parts, is frequently a seed-dispersal tool that attracts animals to eat or otherwise disturb it, incidentally scattering the seeds it contains (see frugivory). Although many such mutualistic relationships remain too fragile to survive competition and to spread widely, flowering proved to be an unusually effective means of reproduction, spreading (whatever its origin) to become the dominant form of land plant life.
Try to answer this question if possible: What did competition prove to be effective at doing?
Answer: unanswerable
Question: The "No Surprises" rule is meant to protect the landowner if "unforeseen circumstances" occur which make the landowner's efforts to prevent or mitigate harm to the species fall short. The "No Surprises" policy may be the most controversial of the recent reforms of the law, because once an Incidental Take Permit is granted, the Fish and Wildlife Service (FWS) loses much ability to further protect a species if the mitigation measures by the landowner prove insufficient. The landowner or permittee would not be required to set aside additional land or pay more in conservation money. The federal government would have to pay for additional protection measures.
Try to answer this question if possible: Why is this particular rule so controversial?
Answer:
the Fish and Wildlife Service (FWS) loses much ability to further protect a species if the mitigation measures by the landowner prove insufficient.
