Problem: Middle Ages:

Romanesque art, especially metalwork, was at its most sophisticated in Mosan art, in which distinct artistic personalities including Nicholas of Verdun (d. 1205) become apparent, and an almost classical style is seen in works such as a font at Liege, contrasting with the writhing animals of the exactly contemporary Gloucester Candlestick. Large illuminated bibles and psalters were the typical forms of luxury manuscripts, and wall-painting flourished in churches, often following a scheme with a Last Judgement on the west wall, a Christ in Majesty at the east end, and narrative biblical scenes down the nave, or in the best surviving example, at Saint-Savin-sur-Gartempe, on the barrel-vaulted roof.

Where are narrative biblical scenes painted in the church at Saint-Savin-sur-Gartempe?
---
A: on the barrel-vaulted roof

Problem: The abbot and monks, in proximity to the royal Palace of Westminster, the seat of government from the later 12th century, became a powerful force in the centuries after the Norman Conquest. The abbot often was employed on royal service and in due course took his place in the House of Lords as of right. Released from the burdens of spiritual leadership, which passed to the reformed Cluniac movement after the mid-10th century, and occupied with the administration of great landed properties, some of which lay far from Westminster, "the Benedictines achieved a remarkable degree of identification with the secular life of their times, and particularly with upper-class life", Barbara Harvey concludes, to the extent that her depiction of daily life provides a wider view of the concerns of the English gentry in the High and Late Middle Ages.[citation needed]
Who became a powerful force after the Norman Conquest?

Context and question: Machine vision systems often require bright and homogeneous illumination, so features of interest are easier to process. LEDs are often used for this purpose, and this is likely to remain one of their major uses until the price drops low enough to make signaling and illumination uses more widespread. Barcode scanners are the most common example of machine vision, and many low cost products use red LEDs instead of lasers. Optical computer mice are an example of LEDs in machine vision, as it is used to provide an even light source on the surface for the miniature camera within the mouse. LEDs constitute a nearly ideal light source for machine vision systems for several reasons:
Why aren't LEDs preferred for machine vision systems?
Answer: unanswerable

Question: ASCII itself was first used commercially during 1963 as a seven-bit teleprinter code for American Telephone & Telegraph's TWX (TeletypeWriter eXchange) network. TWX originally used the earlier five-bit ITA2, which was also used by the competing Telex teleprinter system. Bob Bemer introduced features such as the escape sequence. His British colleague Hugh McGregor Ross helped to popularize this work according to Bemer, "so much so that the code that was to become ASCII was first called the Bemer-Ross Code in Europe". Because of his extensive work on ASCII, Bemer has been called "the father of ASCII."
Is there an answer to this question: Who is the father of ASCII?

Answer: Bob Bemer

Question: Valleys and plains are found along the coastline and rivers. The north of the province lies just south of the Yangtze Delta, and consists of plains around the cities of Hangzhou, Jiaxing, and Huzhou, where the Grand Canal of China enters from the northern border to end at Hangzhou. Another relatively flat area is found along the Qu River around the cities of Quzhou and Jinhua. Major rivers include the Qiangtang and Ou Rivers. Most rivers carve out valleys in the highlands, with plenty of rapids and other features associated with such topography. Well-known lakes include the West Lake of Hangzhou and the South Lake of Jiaxing.
Is there an answer to this question: What is not a well-known lake of Jiaxing?

Answer:
unanswerable
