Problem: Gothic architecture:

Contrary to the diffusionist theory, it appears that there was simultaneously a structural evolution towards the pointed arch, for the purpose of vaulting spaces of irregular plan, or to bring transverse vaults to the same height as diagonal vaults. This latter occurs at Durham Cathedral in the nave aisles in 1093. Pointed arches also occur extensively in Romanesque decorative blind arcading, where semi-circular arches overlap each other in a simple decorative pattern, and the points are accidental to the design.

Which cathedral is the twisted arch used to match the heights of transverse and diagonal vaults?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The hygiene hypothesis attempts to explain the increased rates of asthma worldwide as a direct and unintended result of reduced exposure, during childhood, to non-pathogenic bacteria and viruses. It has been proposed that the reduced exposure to bacteria and viruses is due, in part, to increased cleanliness and decreased family size in modern societies. Exposure to bacterial endotoxin in early childhood may prevent the development of asthma, but exposure at an older age may provoke bronchoconstriction. Evidence supporting the hygiene hypothesis includes lower rates of asthma on farms and in households with pets.
Why are people less likely to want to live on a farm?
A: unanswerable

Context and question: After Babangida survived an abortive coup, he pushed back the promised return to democracy to 1992. Free and fair elections were finally held on 12 June 1993, with a presidential victory for Moshood Kashimawo Olawale Abiola. Babangida annulled the elections, leading to mass civilian violent protests which effectively shut down the country for weeks. Babangida finally kept his promise to relinquish office to a civilian-run government, but not before appointing Ernest Shonekan as head of the interim government. Babangida's regime has been considered the most corrupt, and responsible for creating a culture of corruption in Nigeria.
To when did Babangida delay the return to democracy?
Answer: 1992

Question: The illuminated ceiling was once popular in the 1960s and 1970s but fell out of favor after the 1980s. This uses diffuser panels hung like a suspended ceiling below fluorescent lights, and is considered general lighting. Other forms include neon, which is not usually intended to illuminate anything else, but to actually be an artwork in itself. This would probably fall under accent lighting, though in a dark nightclub it could be considered general lighting.
Is there an answer to this question: When would neon lighting be considered general lighting?

Answer: dark nightclub

When in choir dress, a Latin-rite cardinal wears scarlet garments the blood-like red symbolizes a cardinal's willingness to die for his faith. Excluding the rochet which is always white the scarlet garments include the cassock, mozzetta, and biretta (over the usual scarlet zucchetto). The biretta of a cardinal is distinctive not merely for its scarlet color, but also for the fact that it does not have a pompon or tassel on the top as do the birettas of other prelates. Until the 1460s, it was customary for cardinals to wear a violet or blue cape unless granted the privilege of wearing red when acting on papal business. His normal-wear cassock is black but has scarlet piping and a scarlet fascia (sash). Occasionally, a cardinal wears a scarlet ferraiolo which is a cape worn over the shoulders, tied at the neck in a bow by narrow strips of cloth in the front, without any 'trim' or piping on it. It is because of the scarlet color of cardinals' vesture that the bird of the same name has become known as such.[citation needed]
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The Cardinal bird was named as such because of what in relation to Cardinals of the church?
Ah, so..
the scarlet color of cardinals' vesture
