Context and question: The subsequent 1912 Salon des Indépendants was marked by the presentation of Marcel Duchamp's Nude Descending a Staircase, No. 2, which itself caused a scandal, even amongst the Cubists. It was in fact rejected by the hanging committee, which included his brothers and other Cubists. Although the work was shown in the Salon de la Section d'Or in October 1912 and the 1913 Armory Show in New York, Duchamp never forgave his brothers and former colleagues for censoring his work. Juan Gris, a new addition to the Salon scene, exhibited his Portrait of Picasso (Art Institute of Chicago), while Metzinger's two showings included La Femme au Cheval (Woman with a horse) 1911-1912 (National Gallery of Denmark). Delaunay's monumental La Ville de Paris (Musée d'art moderne de la Ville de Paris) and Léger's La Noce, The Wedding (Musée National d'Art Moderne, Paris) were also exhibited.
What were one of  Metzingers two showings in 1912's Salon des Independants? 
Answer: La Femme au Cheval (Woman with a horse) 1911-1912
Context and question: Electrolytic capacitors use an aluminum or tantalum plate with an oxide dielectric layer. The second electrode is a liquid electrolyte, connected to the circuit by another foil plate. Electrolytic capacitors offer very high capacitance but suffer from poor tolerances, high instability, gradual loss of capacitance especially when subjected to heat, and high leakage current. Poor quality capacitors may leak electrolyte, which is harmful to printed circuit boards. The conductivity of the electrolyte drops at low temperatures, which increases equivalent series resistance. While widely used for power-supply conditioning, poor high-frequency characteristics make them unsuitable for many applications. Electrolytic capacitors will self-degrade if unused for a period (around a year), and when full power is applied may short circuit, permanently damaging the capacitor and usually blowing a fuse or causing failure of rectifier diodes (for instance, in older equipment, arcing in rectifier tubes). They can be restored before use (and damage) by gradually applying the operating voltage, often done on antique vacuum tube equipment over a period of 30 minutes by using a variable transformer to supply AC power. Unfortunately, the use of this technique may be less satisfactory for some solid state equipment, which may be damaged by operation below its normal power range, requiring that the power supply first be isolated from the consuming circuits. Such remedies may not be applicable to modern high-frequency power supplies as these produce full output voltage even with reduced input.
How can electrolytic capacitors be safely used after having been stored unused for a long time?
Answer: by gradually applying the operating voltage
Context and question: The Bovington signal course's director reported that Gaddafi successfully overcame problems learning English, displaying a firm command of voice procedure. Noting that Gaddafi's favourite hobbies were reading and playing football, he thought him an "amusing officer, always cheerful, hard-working, and conscientious." Gaddafi disliked England, claiming British Army officers racially insulted him and finding it difficult adjusting to the country's culture; asserting his Arab identity in London, he walked around Piccadilly wearing traditional Libyan robes. He later related that while he travelled to England believing it more advanced than Libya, he returned home "more confident and proud of our values, ideals and social character."
What language did Gaddafi have difficulty learning?
Answer:
English
