Input: Utrecht
The location on the banks of the river Rhine allowed Utrecht to become an important trade centre in the Northern Netherlands. The growing town Utrecht was granted city rights by Henry V in 1122. When the main flow of the Rhine moved south, the old bed, which still flowed through the heart of the town became evermore canalized; and the wharf system was built as an inner city harbour system. On the wharfs storage facilities (werfkelders) were built, on top of which the main street, including houses was constructed. The wharfs and the cellars are accessible from a platform at water level with stairs descending from the street level to form a unique structure.[nb 2] The relations between the bishop, who controlled many lands outside of the city, and the citizens of Utrecht was not always easy. The bishop, for example dammed the Kromme Rijn at Wijk bij Duurstede to protect his estates from flooding. This threatened shipping for the city and led the city of Utrecht to commission a canal to ensure access to the town for shipping trade: the Vaartse Rijn, connecting Utrecht to the Hollandse IJssel at IJsselstein.

Who granted Utrecht city rights
Output: Henry V in 1122

Input: Article: The current I(t) through any component in an electric circuit is defined as the rate of flow of a charge Q(t) passing through it, but actual chargeselectronscannot pass through the dielectric layer of a capacitor. Rather, one electron accumulates on the negative plate for each one that leaves the positive plate, resulting in an electron depletion and consequent positive charge on one electrode that is equal and opposite to the accumulated negative charge on the other. Thus the charge on the electrodes is equal to the integral of the current as well as proportional to the voltage, as discussed above. As with any antiderivative, a constant of integration is added to represent the initial voltage V(t0). This is the integral form of the capacitor equation:

Now answer this question: To what is the charge on the electrodes of a capacitor equal to?

Output: the integral of the current

Article: With 120,000 students in London, the federal University of London is the largest contact teaching university in the UK. It includes four large multi-faculty universities King's College London, Queen Mary, Royal Holloway and UCL and a number of smaller and more specialised institutions including Birkbeck, the Courtauld Institute of Art, Goldsmiths, Guildhall School of Music and Drama, the Institute of Education, the London Business School, the London School of Economics, the London School of Hygiene & Tropical Medicine, the Royal Academy of Music, the Central School of Speech and Drama, the Royal Veterinary College and the School of Oriental and African Studies. Members of the University of London have their own admissions procedures, and some award their own degrees.

Question: What major university is comprised of four multi-faculty universities and several schools specialized schools?
Ans: University of London

Here is a question about this article: Knots do not necessarily influence the stiffness of structural timber, this will depend on the size and location. Stiffness and elastic strength are more dependent upon the sound wood than upon localized defects. The breaking strength is very susceptible to defects. Sound knots do not weaken wood when subject to compression parallel to the grain.
What is the answer to this question: What do stiffness and elastic strength depend on more than defects?
****
So... sound wood

The Pindus range continues through the central Peloponnese, crosses the islands of Kythera and Antikythera and finds its way into southwestern Aegean, in the island of Crete where it eventually ends. The islands of the Aegean are peaks of underwater mountains that once constituted an extension of the mainland. Pindus is characterized by its high, steep peaks, often dissected by numerous canyons and a variety of other karstic landscapes. The spectacular Vikos Gorge, part of the Vikos-Aoos National Park in the Pindus range, is listed by the Guinness book of World Records as the deepest gorge in the world. Another notable formation are the Meteora rock pillars, atop which have been built medieval Greek Orthodox monasteries.
What is the deepest gorge in the world?
****
The answer: Vikos Gorge

Since 1965, following clashes between the two communities, the Turkish Cypriot seats in the House remain vacant. In 1974 Cyprus was divided de facto when the Turkish army occupied the northern third of the island. The Turkish Cypriots subsequently declared independence in 1983 as the Turkish Republic of Northern Cyprus but were recognised only by Turkey. In 1985 the TRNC adopted a constitution and held its first elections. The United Nations recognises the sovereignty of the Republic of Cyprus over the entire island of Cyprus.
What organization recognizes the sovereignty of the Republic of Cyprus?
****
The answer:
The United Nations
