The average net household income (after social, pension and health insurance contributions) in Paris was €36,085 for 2011. It ranged from €22,095 in the 19th arrondissement to €82,449 in the 7th arrondissement. The median taxable income for 2011 was around €25,000 in Paris and €22,200 for Île-de-France. Generally speaking, incomes are higher in the Western part of the city and in the western suburbs than in the northern and eastern parts of the urban area.[citation needed] Unemployment was estimated at 8.2 percent in the city of Paris and 8.8 percent in the Île-de-France region in the first trimester of 2015. It ranged from 7.6 percent in the wealthy Essonne department to 13.1 percent in the Seine-Saint-Denis department, where many recent immigrants live.
What was the unemployment rate in the city of Paris?
****
The answer: 8.2

In 1853, Victoria gave birth to her eighth child, Leopold, with the aid of the new anaesthetic, chloroform. Victoria was so impressed by the relief it gave from the pain of childbirth that she used it again in 1857 at the birth of her ninth and final child, Beatrice, despite opposition from members of the clergy, who considered it against biblical teaching, and members of the medical profession, who thought it dangerous. Victoria may have suffered from post-natal depression after many of her pregnancies. Letters from Albert to Victoria intermittently complain of her loss of self-control. For example, about a month after Leopold's birth Albert complained in a letter to Victoria about her "continuance of hysterics" over a "miserable trifle".
Who was Victoria's eighth child?
****
The answer: Leopold


The problem: Answer a question about this article:
When an inductive circuit is opened, the current through the inductance collapses quickly, creating a large voltage across the open circuit of the switch or relay. If the inductance is large enough, the energy will generate a spark, causing the contact points to oxidize, deteriorate, or sometimes weld together, or destroying a solid-state switch. A snubber capacitor across the newly opened circuit creates a path for this impulse to bypass the contact points, thereby preserving their life; these were commonly found in contact breaker ignition systems, for instance. Similarly, in smaller scale circuits, the spark may not be enough to damage the switch but will still radiate undesirable radio frequency interference (RFI), which a filter capacitor absorbs. Snubber capacitors are usually employed with a low-value resistor in series, to dissipate energy and minimize RFI. Such resistor-capacitor combinations are available in a single package.
What happens to the voltage when an inductive circuit is opened?
****
The answer: a large voltage across the open circuit of the switch


The problem: Answer a question about this article:
Gene nomenclature has been established by the HUGO Gene Nomenclature Committee (HGNC) for each known human gene in the form of an approved gene name and symbol (short-form abbreviation), which can be accessed through a database maintained by HGNC. Symbols are chosen to be unique, and each gene has only one symbol (although approved symbols sometimes change). Symbols are preferably kept consistent with other members of a gene family and with homologs in other species, particularly the mouse due to its role as a common model organism.
How many symbols does each gene have?
****
The answer:
only one
