Input: Read this: To put it another way, a thing or person is often seen as having a "defining essence" or a "core identity" that is unchanging, and describes what the thing or person really is. In this way of thinking, things and people are seen as fundamentally the same through time, with any changes being qualitative and secondary to their core identity (e.g. "Mark's hair has turned gray as he has gotten older, but he is still the same person"). But in Whitehead's cosmology, the only fundamentally existent things are discrete "occasions of experience" that overlap one another in time and space, and jointly make up the enduring person or thing. On the other hand, what ordinary thinking often regards as "the essence of a thing" or "the identity/core of a person" is an abstract generalization of what is regarded as that person or thing's most important or salient features across time. Identities do not define people, people define identities. Everything changes from moment to moment, and to think of anything as having an "enduring essence" misses the fact that "all things flow", though it is often a useful way of speaking.
Question: The idea that people are changing and stay the same even through changes is considered what?

Output: unanswerable


QUES: Gram quantities of various copper salts have been taken in suicide attempts and produced acute copper toxicity in humans, possibly due to redox cycling and the generation of reactive oxygen species that damage DNA. Corresponding amounts of copper salts (30 mg/kg) are toxic in animals. A minimum dietary value for healthy growth in rabbits has been reported to be at least 3 ppm in the diet. However, higher concentrations of copper (100 ppm, 200 ppm, or 500 ppm) in the diet of rabbits may favorably influence feed conversion efficiency, growth rates, and carcass dressing percentages.

When ingested in large amounts what does copper salts produce in humans?
What is the answer?
ANS: copper toxicity


QUES: There do exist orbits within these empty regions where objects can survive for the age of the Solar System. These resonances occur when Neptune's orbital period is a precise fraction of that of the object, such as 1:2, or 3:4. If, say, an object orbits the Sun once for every two Neptune orbits, it will only complete half an orbit by the time Neptune returns to its original position. The most heavily populated resonance in the Kuiper belt, with over 200 known objects, is the 2:3 resonance. Objects in this resonance complete 2 orbits for every 3 of Neptune, and are known as plutinos because the largest of the known Kuiper belt objects, Pluto, is among them. Although Pluto crosses Neptune's orbit regularly, the 2:3 resonance ensures they can never collide. The 3:4, 3:5, 4:7 and 2:5 resonances are less populated.
 What is the least known object in the Kuiper belt?

By 1976, Queen were back in the studio recording A Day at the Races, which is often regarded as a sequel album to A Night at the Opera. It again borrowed the name of a Marx Brothers movie, and its cover was similar to that of A Night at the Opera, a variation on the same Queen Crest. The most recognisable of the Marx Brothers, Groucho Marx, invited Queen to visit him in his Los Angeles home in March 1977; there the band thanked him in person, and performed "'39" a cappella. Musically, A Day at the Races was by both fans' and critics' standards a strong effort, reaching number one in the UK and Japan, and number five in the US. The major hit on the album was "Somebody to Love", a gospel-inspired song in which Mercury, May, and Taylor multi-tracked their voices to create a 100-voice gospel choir. The song went to number two in the UK, and number thirteen in the US. The album also featured one of the band's heaviest songs, May's "Tie Your Mother Down", which became a staple of their live shows.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What Queen album was released in 1976?
Ah, so.. A Day at the Races


Question: A new style of wafers composed of gallium-nitride-on-silicon (GaN-on-Si) is being used to produce white LEDs using 200-mm silicon wafers. This avoids the typical costly sapphire substrate in relatively small 100- or 150-mm wafer sizes. The sapphire apparatus must be coupled with a mirror-like collector to reflect light that would otherwise be wasted. It is predicted that by 2020, 40% of all GaN LEDs will be made with GaN-on-Si. Manufacturing large sapphire material is difficult, while large silicon material is cheaper and more abundant. LED companies shifting from using sapphire to silicon should be a minimal investment.
Try to answer this question if possible: What needs to not be used to reflect light that would otherwise be wasted?
Answer: unanswerable


Question: Although a resonant antenna has a purely resistive feed-point impedance at a particular frequency, many (if not most) applications require using an antenna over a range of frequencies. An antenna's bandwidth specifies the range of frequencies over which its performance does not suffer due to a poor impedance match. Also in the case of a Yagi-Uda array, the use of the antenna very far away from its design frequency reduces the antenna's directivity, thus reducing the usable bandwidth regardless of impedance matching.
Try to answer this question if possible: What type of antenna has impedance at a specific frequency?
Answer:
resonant
