Problem: Utrecht:

Utrecht's cityscape is dominated by the Dom Tower, the tallest belfry in the Netherlands and originally part of the Cathedral of Saint Martin. An ongoing debate is over whether any building in or near the centre of town should surpass the Dom Tower in height (112 m). Nevertheless, some tall buildings are now being constructed that will become part of the skyline of Utrecht. The second tallest building of the city, the Rabobank-tower, was completed in 2010 and stands 105 m (344.49 ft) tall. Two antennas will increase that height to 120 m (393.70 ft). Two other buildings were constructed around the Nieuw Galgenwaard stadium (2007). These buildings, the 'Kantoortoren Galghenwert' and 'Apollo Residence', stand 85.5 and 64.5 metres high respectively.

What tower was completed int he 20th century?

Problem: After the President signs a bill into law (or Congress enacts it over his veto), it is delivered to the Office of the Federal Register (OFR) of the National Archives and Records Administration (NARA) where it is assigned a law number, and prepared for publication as a slip law. Public laws, but not private laws, are also given legal statutory citation by the OFR. At the end of each session of Congress, the slip laws are compiled into bound volumes called the United States Statutes at Large, and they are known as session laws. The Statutes at Large present a chronological arrangement of the laws in the exact order that they have been enacted.
What organization gives private laws legal statutory citations?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
At the time structures such as Lie algebras and hyperbolic quaternions drew attention to the need to expand algebraic structures beyond the associatively multiplicative class. In a review Alexander Macfarlane wrote: "The main idea of the work is not unification of the several methods, nor generalization of ordinary algebra so as to include them, but rather the comparative study of their several structures." In a separate review, G. B. Mathews wrote, "It possesses a unity of design which is really remarkable, considering the variety of its themes."
Reviewer Alexander Macfarlane believed that the main idea of the work is a comparative study of what?
A: several structures

Context and question: The Dutch East India Company had founded the Cape Colony on the southern tip of Africa in 1652 as a way station for its ships travelling to and from its colonies in the East Indies. Britain formally acquired the colony, and its large Afrikaner (or Boer) population in 1806, having occupied it in 1795 to prevent its falling into French hands, following the invasion of the Netherlands by France. British immigration began to rise after 1820, and pushed thousands of Boers, resentful of British rule, northwards to found their ownmostly short-livedindependent republics, during the Great Trek of the late 1830s and early 1840s. In the process the Voortrekkers clashed repeatedly with the British, who had their own agenda with regard to colonial expansion in South Africa and with several African polities, including those of the Sotho and the Zulu nations. Eventually the Boers established two republics which had a longer lifespan: the South African Republic or Transvaal Republic (185277; 18811902) and the Orange Free State (18541902). In 1902 Britain occupied both republics, concluding a treaty with the two Boer Republics following the Second Boer War (18991902).
When was the southern tip of Africa colonized?
Answer: 1652

Question: The Romantic Movement of the early 19th century reshaped science by opening up new pursuits unexpected in the classical approaches of the Enlightenment. Major breakthroughs came in biology, especially in Darwin's theory of evolution, as well as physics (electromagnetism), mathematics (non-Euclidean geometry, group theory) and chemistry (organic chemistry). The decline of Romanticism occurred because a new movement, Positivism, began to take hold of the ideals of the intellectuals after 1840 and lasted until about 1880.
Is there an answer to this question: What theory did Darwin introduce?

Answer: theory of evolution

The idea of Masonic brotherhood probably descends from a 16th-century legal definition of a brother as one who has taken an oath of mutual support to another. Accordingly, Masons swear at each degree to keep the contents of that degree secret, and to support and protect their brethren unless they have broken the law. In most Lodges the oath or obligation is taken on a Volume of Sacred Law, whichever book of divine revelation is appropriate to the religious beliefs of the individual brother (usually the Bible in the Anglo-American tradition). In Progressive continental Freemasonry, books other than scripture are permissible, a cause of rupture between Grand Lodges.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What can be considered a Volume of Sacred Law?
Ah, so..
whichever book of divine revelation is appropriate to the religious beliefs of the individual brother
