Problem: Paris:

The Paris Region economy has gradually shifted from industry to high-value-added service industries (finance, IT services, etc.) and high-tech manufacturing (electronics, optics, aerospace, etc.). The Paris region's most intense economic activity through the central Hauts-de-Seine department and suburban La Defense business district places Paris' economic centre to the west of the city, in a triangle between the Opera Garnier, La Defense and the Val de Seine. While the Paris economy is dominated by services, and employment in manufacturing sector has declined sharply, the region remains an important manufacturing centre, particularly for aeronautics, automobiles, and "eco" industries.

What as the Paris Region's economy shifted towards?
---
A: high-value-added service industries

Problem: On Thursday, September 19, 1985, at 7:19 am local time, Mexico City was struck by an earthquake of magnitude 8.1 on the Richter scale. Although this earthquake was not as deadly or destructive as many similar events in Asia and other parts of Latin America, it proved to be a disaster politically for the one-party government. The government was paralyzed by its own bureaucracy and corruption, forcing ordinary citizens to create and direct their own rescue efforts and to reconstruct much of the housing that was lost as well.
Who led the rescue effort after the earthquake of 1985?
---
Answer: ordinary citizens

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The Logic and Metaphysics have been extensively reprinted, the latter, e.g., at Venice in 1493, 1495, and 1546. Some of his shorter essays on medicine, logic, etc., take a poetical form (the poem on logic was published by Schmoelders in 1836).[citation needed] Two encyclopaedic treatises, dealing with philosophy, are often mentioned. The larger, Al-Shifa' (Sanatio), exists nearly complete in manuscript in the Bodleian Library and elsewhere; part of it on the De Anima appeared at Pavia (1490) as the Liber Sextus Naturalium, and the long account of Ibn Sina's philosophy given by Muhammad al-Shahrastani seems to be mainly an analysis, and in many places a reproduction, of the Al-Shifa'. A shorter form of the work is known as the An-najat (Liberatio). The Latin editions of part of these works have been modified by the corrections which the monastic editors confess that they applied. There is also a (hikmat-al-mashriqqiyya, in Latin Philosophia Orientalis), mentioned by Roger Bacon, the majority of which is lost in antiquity, which according to Averroes was pantheistic in tone.
What is the shorter form of Al-Shifa called?
A: the An-najat

Context and question: In the late 17th century, Gottfried Leibniz proposed the idea of the Latin: vis viva, or living force, which defined as the product of the mass of an object and its velocity squared; he believed that total vis viva was conserved. To account for slowing due to friction, Leibniz theorized that thermal energy consisted of the random motion of the constituent parts of matter, a view shared by Isaac Newton, although it would be more than a century until this was generally accepted. The modern analog of this property, kinetic energy, differs from vis viva only by a factor of two.
In what century did Leibniz propose the idea of Latin: vis viva?
Answer: late 17th century

Question: Internationally, Victoria took a keen interest in the improvement of relations between France and Britain. She made and hosted several visits between the British royal family and the House of Orleans, who were related by marriage through the Coburgs. In 1843 and 1845, she and Albert stayed with King Louis Philippe I at chateau d'Eu in Normandy; she was the first British or English monarch to visit a French one since the meeting of Henry VIII of England and Francis I of France on the Field of the Cloth of Gold in 1520. When Louis Philippe made a reciprocal trip in 1844, he became the first French king to visit a British sovereign. Louis Philippe was deposed in the revolutions of 1848, and fled to exile in England. At the height of a revolutionary scare in the United Kingdom in April 1848, Victoria and her family left London for the greater safety of Osborne House, a private estate on the Isle of Wight that they had purchased in 1845 and redeveloped. Demonstrations by Chartists and Irish nationalists failed to attract widespread support, and the scare died down without any major disturbances. Victoria's first visit to Ireland in 1849 was a public relations success, but it had no lasting impact or effect on the growth of Irish nationalism.
Is there an answer to this question: When was Osborne house purchased?

Answer: 1845

Bacteria do not have a membrane-bound nucleus, and their genetic material is typically a single circular DNA chromosome located in the cytoplasm in an irregularly shaped body called the nucleoid. The nucleoid contains the chromosome with its associated proteins and RNA. The phylum Planctomycetes and candidate phylum Poribacteria may be exceptions to the general absence of internal membranes in bacteria, because they appear to have a double membrane around their nucleoids and contain other membrane-bound cellular structures. Like all living organisms, bacteria contain ribosomes, often grouped in chains called polyribosomes, for the production of proteins, but the structure of the bacterial ribosome is different from that of eukaryotes and Archaea. Bacterial ribosomes have a sedimentation rate of 70S (measured in Svedberg units): their subunits have rates of 30S and 50S. Some antibiotics bind specifically to 70S ribosomes and inhibit bacterial protein synthesis. Those antibiotics kill bacteria without affecting the larger 80S ribosomes of eukaryotic cells and without harming the host.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What are the exceptions of non-internal membrane bacteria?
Ah, so..
phylum Planctomycetes and candidate phylum Poribacteria
