Problem: Mosaic:

Islamic architecture used mosaic technique to decorate religious buildings and palaces after the Muslim conquests of the eastern provinces of the Byzantine Empire. In Syria and Egypt the Arabs were influenced by the great tradition of Roman and Early Christian mosaic art. During the Umayyad Dynasty mosaic making remained a flourishing art form in Islamic culture and it is continued in the art of zellige and azulejo in various parts of the Arab world, although tile was to become the main Islamic form of wall decoration.

The Umayyad Dynasty made mosaic making do what in the Islamic culture?

A: remained a flourishing art form

Problem: Later, the 3rd dynasty of Ur under Ur-Nammu and Shulgi, whose power extended as far as southern Assyria, was the last great "Sumerian renaissance", but already the region was becoming more Semitic than Sumerian, with the rise in power of the Akkadian speaking Semites in Assyria and elsewhere, and the influx of waves of Semitic Martu (Amorites) who were to found several competing local powers including Isin, Larsa, Eshnunna and eventually Babylon. The last of these eventually came to dominate the south of Mesopotamia as the Babylonian Empire, just as the Old Assyrian Empire had already done so in the north from the late 21st century BC. The Sumerian language continued as a sacerdotal language taught in schools in Babylonia and Assyria, much as Latin was used in the Medieval period, for as long as cuneiform was utilized.
Where was the power of Akkadian speaking Semites declining?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The so-called "Sack of Palermo" is one of the major visible faces of the problem. The term is used to indicate the speculative building practices that have filled the city with poor buildings. The reduced importance of agriculture in the Sicilian economy has led to a massive migration to the cities, especially Palermo, which swelled in size, leading to rapid expansion towards the north. The regulatory plans for expansion was largely ignored in the boom. New parts of town appeared almost out of nowhere, but without parks, schools, public buildings, proper roads and the other amenities that characterise a modern city.
What is the term for the building boom erected many fine buildings?
A: unanswerable

Context and question: When there is a potential difference across the conductors (e.g., when a capacitor is attached across a battery), an electric field develops across the dielectric, causing positive charge +Q to collect on one plate and negative charge Q to collect on the other plate. If a battery has been attached to a capacitor for a sufficient amount of time, no current can flow through the capacitor. However, if a time-varying voltage is applied across the leads of the capacitor, a displacement current can flow.
How do charges accumulate on each plate of a capacitor after an electric field has developed across the dielectric?
Answer: positive charge +Q to collect on one plate and negative charge Q to collect on the other

Question: However, leeches and their closest relatives have a body structure that is very uniform within the group but significantly different from that of other annelids, including other members of the Clitellata. In leeches there are no septa, the connective tissue layer of the body wall is so thick that it occupies much of the body, and the two coelomata are widely separated and run the length of the body. They function as the main blood vessels, although they are side-by-side rather than upper and lower. However, they are lined with mesothelium, like the coelomata and unlike the blood vessels of other annelids. Leeches generally use suckers at their front and rear ends to move like inchworms. The anus is on the upper surface of the pygidium.
Is there an answer to this question: How many brains do leeches have?

Answer: unanswerable

In 1972, in a mosque in the city of Sana'a, Yemen, manuscripts were discovered that were later proved to be the most ancient Quranic text known to exist at the time. The Sana'a manuscripts contain palimpsests, a manuscript page from which the text has been washed off to make the parchment reusable againa practice which was common in ancient times due to scarcity of writing material. However, the faint washed-off underlying text (scriptio inferior) is still barely visible and believed to be "pre-Uthmanic" Quranic content, while the text written on top (scriptio superior) is believed to belong to Uthmanic time. Studies using radiocarbon dating indicate that the parchments are dated to the period before 671 AD with a 99 percent probability.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In which city was evidence of pre-Uthmanic Quranic writing discovered in 1927?
Ah, so..
unanswerable
