Input: BeiDou Navigation Satellite System
In 2008, a BeiDou-1 ground terminal cost around CN¥20,000RMB (US$2,929), almost 10 times the price of a contemporary GPS terminal. The price of the terminals was explained as being due to the cost of imported microchips. At the China High-Tech Fair ELEXCON of November 2009 in Shenzhen, a BeiDou terminal priced at CN¥3,000RMB was presented.

How much more did a BeiDou-1 ground terminal cost than a current GPS terminal?
Output: almost 10 times the price


Input: Article: The first attempt to establish a proper governing body and adopted the current set of Rugby rules was the Foot Ball Association of Canada, organized on March 24, 1873 followed by the Canadian Rugby Football Union (CRFU) founded June 12, 1880, which included teams from Ontario and Quebec. Later both the Ontario and Quebec Rugby Football Union (ORFU and QRFU) were formed (January 1883), and then the Interprovincial (1907) and Western Interprovincial Football Union (1936) (IRFU and WIFU). The CRFU reorganized into an umbrella organization forming the Canadian Rugby Union (CRU) in 1891. The original forerunners to the current Canadian Football League, was established in 1956 when the IRFU and WIFU formed an umbrella organization, The Canadian Football Council (CFC). And then in 1958 the CFC left The CRFU to become The CFL.

Now answer this question: Which governing organization for Canadian football was formed on June 12, 1880?

Output: Canadian Rugby Football Union


Article: A boy who is late for any division or other appointment may be required to sign "Tardy Book", a register kept in the School Office, between 7.35am and 7.45am, every morning for the duration of his sentence (typically three days). Tardy Book may also be issued for late work. For more serious misdeeds, a boy is summoned from his lessons to the Head Master, or Lower Master if the boy is in the lower two years, to talk personally about his misdeeds. This is known as the "Bill". The most serious misdeeds may result in expulsion, or rustication (suspension). Conversely, should a master be more than 15 minutes late for a class, traditionally the pupils might claim it as a "run" and absent themselves for the rest of its duration.

Question: How long is the typical punishment for being tardy?
Ans: typically three days


Here is a question about this article: In April 2010, Shell announced its intention to divest from downstream business of all African countries except South Africa and Egypt to Vitol and "Helios".

What is the answer to this question: In August 2014, Shell announced it was in the process of doing what?
****
So... finalizing the sale of its interests in four Nigerian oil fields.


The problem: Answer a question about this article:
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 metanephridia remove?
****
The answer: soluble waste products


The problem: Answer a question about this article:
Anthropology of development tends to view development from a critical perspective. The kind of issues addressed and implications for the approach simply involve pondering why, if a key development goal is to alleviate poverty, is poverty increasing? Why is there such a gap between plans and outcomes? Why are those working in development so willing to disregard history and the lessons it might offer? Why is development so externally driven rather than having an internal basis? In short why does so much planned development fail?
What perspective does development anthropology view development from?
****
The answer:
critical
