Problem: Please answer a question about the following article about Imperial College London:
The Royal College of Chemistry was established by private subscription in 1845 as there was a growing awareness that practical aspects of the experimental sciences were not well taught and that in the United Kingdom the teaching of chemistry in particular had fallen behind that in Germany. As a result of a movement earlier in the decade, many politicians donated funds to establish the college, including Benjamin Disraeli, William Gladstone and Robert Peel. It was also supported by Prince Albert, who persuaded August Wilhelm von Hofmann to be the first professor.
Which country was ahead of the United Kingdom in the teaching of chemistry?
A: Germany
Problem: Please answer a question about the following article about Annelid:
Annelids with blood vessels use metanephridia to remove soluble waste products, while those without use protonephridia. Both of these systems use a two-stage filtration process, in which fluid and waste products are first extracted and these are filtered again to re-absorb any re-usable materials while dumping toxic and spent materials as urine. The difference is that protonephridia combine both filtration stages in the same organ, while metanephridia perform only the second filtration and rely on other mechanisms for the first in annelids special filter cells in the walls of the blood vessels let fluids and other small molecules pass into the coelomic fluid, where it circulates to the metanephridia. In annelids the points at which fluid enters the protonephridia or metanephridia are on the forward side of a septum while the second-stage filter and the nephridiopore (exit opening in the body wall) are in the following segment. As a result, the hindmost segment (before the growth zone and pygidium) has no structure that extracts its wastes, as there is no following segment to filter and discharge them, while the first segment contains an extraction structure that passes wastes to the second, but does not contain the structures that re-filter and discharge urine.
What do annelids without blood vessels do to remove waste?
A: protonephridia
Problem: Please answer a question about the following article about Warsaw Pact:
In November 2005, the Polish government opened its Warsaw Treaty archives to the Institute of National Remembrance, who published some 1,300 declassified documents in January 2006. Yet the Polish government reserved publication of 100 documents, pending their military declassification. Eventually, 30 of the reserved 100 documents were published; 70 remained secret, and unpublished. Among the documents published is the Warsaw Treaty's nuclear war plan, Seven Days to the River Rhine a short, swift counter-attack capturing Austria, Denmark, Germany and Netherlands east of River Rhine, using nuclear weapons, in self-defense, after a NATO first strike. The plan originated as a 1979 field training exercise war game, and metamorphosed into official Warsaw Treaty battle doctrine, until the late 1980s which is why the People's Republic of Poland was a nuclear weapons base, first, to 178, then, to 250 tactical-range rockets. Doctrinally, as a Soviet-style (offensive) battle plan, Seven Days to the River Rhine gave commanders few defensive-war strategies for fighting NATO in Warsaw Treaty territory.[citation needed]
How many documents remain classified?
A: 70
Problem: Please answer a question about the following article about Film speed:
On an international level the German DIN 4512 system has been effectively superseded in the 1980s by ISO 6:1974, ISO 2240:1982, and ISO 5800:1979 where the same sensitivity is written in linear and logarithmic form as "ISO 100/21" (now again with degree symbol). These ISO standards were subsequently adopted by DIN as well. Finally, the latest DIN 4512 revisions were replaced by corresponding ISO standards, DIN 4512-1:1993-05 by DIN ISO 6:1996-02 in September 2000, DIN 4512-4:1985-08 by DIN ISO 2240:1998-06 and DIN 4512-5:1990-11 by DIN ISO 5800:1998-06 both in July 2002.
What standards did the DIN begin to use?
A:
ISO standards
