Problem: Kathmandu:

The neighbourhood of Thamel is Kathmandu's primary "traveller's ghetto", packed with guest houses, restaurants, shops, and bookstores, catering to tourists. Another neighbourhood of growing popularity is Jhamel, a name for Jhamsikhel coined to rhyme with Thamel. Jhochhen Tol, also known as Freak Street, is Kathmandu's original traveler's haunt, made popular by the hippies of the 1960s and 1970s; it remains a popular alternative to Thamel. Asan is a bazaar and ceremonial square on the old trade route to Tibet, and provides a fine example of a traditional neighbourhood.

What Kathmandu neighborhood is noted for its abundance of tourists?

A: Thamel

Problem: Starting in the coal mines, by the mid-19th century elevators were operated with steam power and were used for moving goods in bulk in mines and factories. These steam driven devices were soon being applied to a diverse set of purposes - in 1823, two architects working in London, Burton and Hormer, built and operated a novel tourist attraction, which they called the "ascending room". It elevated paying customers to a considerable height in the center of London, allowing them a magnificent panoramic view of downtown.
What were elevators originally built for?

Answer: moving goods in bulk in mines and factories

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
It is admitted that the doctrine as defined by Pius IX was not explicitly mooted before the 12th century. It is also agreed that "no direct or categorical and stringent proof of the dogma can be brought forward from Scripture". But it is claimed that the doctrine is implicitly contained in the teaching of the Fathers. Their expressions on the subject of the sinlessness of Mary are, it is pointed out, so ample and so absolute that they must be taken to include original sin as well as actual. Thus in the first five centuries such epithets as "in every respect holy", "in all things unstained", "super-innocent", and "singularly holy" are applied to her; she is compared to Eve before the fall, as ancestress of a redeemed people; she is "the earth before it was accursed". The well-known words of St. Augustine (d. 430) may be cited: "As regards the mother of God," he says, "I will not allow any question whatever of sin." It is true that he is here speaking directly of actual or personal sin. But his argument is that all men are sinners; that they are so through original depravity; that this original depravity may be overcome by the grace of God, and he adds that he does not know but that Mary may have had sufficient grace to overcome sin "of every sort" (omni ex parte).
What proof do some believe is offered as to proof of Mary being the ultimate concept of pure?
A: include original sin as well as actual. Thus in the first five centuries such epithets as "

Context and question: Paper at this point is uncoated. Coated paper has a thin layer of material such as calcium carbonate or china clay applied to one or both sides in order to create a surface more suitable for high-resolution halftone screens. (Uncoated papers are rarely suitable for screens above 150 lpi.) Coated or uncoated papers may have their surfaces polished by calendering. Coated papers are divided into matte, semi-matte or silk, and gloss. Gloss papers give the highest optical density in the printed image.
Which type of papers are not divided into matte, smei-matte or silk and gloss?
Answer: unanswerable

Question: The late Georgian period saw the birth of the semi-detached house, planned systematically, as a suburban compromise between the terraced houses of the city and the detached "villas" further out, where land was cheaper. There had been occasional examples in town centres going back to medieval times. Most early suburban examples are large, and in what are now the outer fringes of Central London, but were then in areas being built up for the first time. Blackheath, Chalk Farm and St John's Wood are among the areas contesting being the original home of the semi. Sir John Summerson gave primacy to the Eyre Estate of St John's Wood. A plan for this exists dated 1794, where "the whole development consists of pairs of semi-detached houses, So far as I know, this is the first recorded scheme of the kind". In fact the French Wars put an end to this scheme, but when the development was finally built it retained the semi-detached form, "a revolution of striking significance and far-reaching effect".
Is there an answer to this question: Which city is agreed to be the first to have semi detached houses?

Answer: unanswerable

QUES: The earliest known macrofossil confidently identified as an angiosperm, Archaefructus liaoningensis, is dated to about 125 million years BP (the Cretaceous period), whereas pollen considered to be of angiosperm origin takes the fossil record back to about 130 million years BP. However, one study has suggested that the early-middle Jurassic plant Schmeissneria, traditionally considered a type of ginkgo, may be the earliest known angiosperm, or at least a close relative. In addition, circumstantial chemical evidence has been found for the existence of angiosperms as early as 250 million years ago. Oleanane, a secondary metabolite produced by many flowering plants, has been found in Permian deposits of that age together with fossils of gigantopterids. Gigantopterids are a group of extinct seed plants that share many morphological traits with flowering plants, although they are not known to have been flowering plants themselves.

How long ago has circumstantial evidence has been found for the existence of angiosperms?
