Input: 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.

Now answer this question: How many stages are there in annelids' waste filtration?

Output: two


Article: The Free Officers' intention was not to install themselves in government, but to re-establish a parliamentary democracy. Nasser did not believe that a low-ranking officer like himself (a lieutenant colonel) would be accepted by the Egyptian people, and so selected General Naguib to be his "boss" and lead the coup in name. The revolution they had long sought was launched on 22 July and was declared a success the next day. The Free Officers seized control of all government buildings, radio stations, and police stations, as well as army headquarters in Cairo. While many of the rebel officers were leading their units, Nasser donned civilian clothing to avoid detection by royalists and moved around Cairo monitoring the situation. In a move to stave off foreign intervention two days before the revolution, Nasser had notified the American and British governments of his intentions, and both had agreed not to aid Farouk. Under pressure from the Americans, Nasser had agreed to exile the deposed king with an honorary ceremony.

Question: What type of government did the Free Officer's want to establish?
Ans: parliamentary democracy


Here is a question about this article: Following a custom she maintained throughout her widowhood, Victoria spent the Christmas of 1900 at Osborne House on the Isle of Wight. Rheumatism in her legs had rendered her lame, and her eyesight was clouded by cataracts.

What is the answer to this question: Who was Queen Victoria's successor?
****
So... King Edward VII


The problem: Answer a question about this article:
Matrix groups consist of matrices together with matrix multiplication. The general linear group GL(n, R) consists of all invertible n-by-n matrices with real entries. Its subgroups are referred to as matrix groups or linear groups. The dihedral group example mentioned above can be viewed as a (very small) matrix group. Another important matrix group is the special orthogonal group SO(n). It describes all possible rotations in n dimensions. Via Euler angles, rotation matrices are used in computer graphics.
What groups combine matrices with matrix multiplication?
****
The answer: Matrix groups


Problem: Please answer a question about the following article about War on Terror:
The British 16th Air Assault Brigade (later reinforced by Royal Marines) formed the core of the force in southern Afghanistan, along with troops and helicopters from Australia, Canada and the Netherlands. The initial force consisted of roughly 3,300 British, 2,000 Canadian, 1,400 from the Netherlands and 240 from Australia, along with special forces from Denmark and Estonia and small contingents from other nations. The monthly supply of cargo containers through Pakistani route to ISAF in Afghanistan is over 4,000 costing around 12 billion in Pakistani Rupees.
How many troops did Canada send initially?
A: 2,000

Southampton is a major UK port which has good transport links with the rest of the country. The M27 motorway, linking places along the south coast of England, runs just to the north of the city. The M3 motorway links the city to London and also, via a link to the A34 (part of the European route E05) at Winchester, with the Midlands and North. The M271 motorway is a spur of the M27, linking it with the Western Docks and city centre.

Which motorway connects Southampton to London?
Answer:
M3
