Problem: Please answer a question about the following article about Hydrogen:
Compounds of hydrogen are often called hydrides, a term that is used fairly loosely. The term "hydride" suggests that the H atom has acquired a negative or anionic character, denoted H, and is used when hydrogen forms a compound with a more electropositive element. The existence of the hydride anion, suggested by Gilbert N. Lewis in 1916 for group I and II salt-like hydrides, was demonstrated by Moers in 1920 by the electrolysis of molten lithium hydride (LiH), producing a stoichiometry quantity of hydrogen at the anode. For hydrides other than group I and II metals, the term is quite misleading, considering the low electronegativity of hydrogen. An exception in group II hydrides is BeH
2, which is polymeric. In lithium aluminium hydride, the AlH
4 anion carries hydridic centers firmly attached to the Al(III).
What group of hydrides is BEH considered polymeric?
A: group II
Problem: Please answer a question about the following article about Hindu philosophy:
The Vaisesika philosophy is a naturalist school; it is a form of atomism in natural philosophy. It postulated that all objects in the physical universe are reducible to paramanu (atoms), and one's experiences are derived from the interplay of substance (a function of atoms, their number and their spatial arrangements), quality, activity, commonness, particularity and inherence. Knowledge and liberation was achievable by complete understanding of the world of experience, according to Vaisesika school . The Vaisesika darsana is credited to Kanada Kasyapa from the second half of the first millennium BCE. The foundational text, the Vaisesika Sutra, opens as follows,
What philosophy is a naturalist school?
A: Vaisesika
Problem: Please answer a question about the following article about Plymouth:
In the nearby parish of Stoke Damerel the first dockyard, HMNB Devonport, opened in 1690 on the eastern bank of the River Tamar. Further docks were built here in 1727, 1762 and 1793. The settlement that developed here was called "Dock" or "Plymouth Dock" at the time, and a new town, separate from Plymouth, grew up. In 1712 there were 318 men employed and by 1733 it had grown to a population of 3,000 people.
What was the 1733 population of Plymouth Dock?
A: 3,000
Problem: Please answer a question about the following article about Karl Popper:
He does not argue that any such conclusions are therefore true, or that this describes the actual methods of any particular scientist.[citation needed] Rather, it is recommended as an essential principle of methodology that, if enacted by a system or community, will lead to slow but steady progress of a sort (relative to how well the system or community enacts the method). It has been suggested that Popper's ideas are often mistaken for a hard logical account of truth because of the historical co-incidence of their appearing at the same time as logical positivism, the followers of which mistook his aims for their own.
Popper has stressed that his description of scientific methodology should not be mistaken to apply to whom?
A:
any particular scientist
