Article: Madonna's initial music videos reflected her American and Hispanic mixed street style combined with a flamboyant glamor. She was able to transmit her avant-garde downtown New York fashion sense to the American audience. The imagery and incorporation of Hispanic culture and Catholic symbolism continued with the music videos from the True Blue era. Author Douglas Kellner noted, "such 'multiculturalism' and her culturally transgressive moves turned out to be highly successful moves that endeared her to large and varied youth audiences." Madonna's Spanish look in the videos became the fashion trend of that time, in the form of boleros and layered skirts, accessorizing with rosary beads and a crucifix as in the video of "La Isla Bonita".

Question: Which look of Madonna became a fashion trend?
Ans: Spanish look


Article: In July 2013, there were 41,000 non-Germans by citizenship living in Thuringia (1.9% of the population − among the smallest proportions of any state in Germany). Nevertheless, the number rose from 33,000 in July 2011, an increase of 24% in only two years. About 4% of the population are migrants (including persons that already received the German citizenship). The biggest groups of foreigners by citizenship are (as of 2012): Russians (3,100), Poles (3,000), Vietnamese (2,800), Turks (2,100) and Ukrainians (2,000). The amount of foreigners varies between regions: the college towns Erfurt, Jena, Weimar and Ilmenau have the highest rates, whereas there are almost no migrants living in the most rural smaller municipalities.

Question: How much of the Thuringian population are migrants?
Ans: 4%


Article:  Capacitors deviate from the ideal capacitor equation in a number of ways. Some of these, such as leakage current and parasitic effects are linear, or can be assumed to be linear, and can be dealt with by adding virtual components to the equivalent circuit of the capacitor. The usual methods of network analysis can then be applied. In other cases, such as with breakdown voltage, the effect is non-linear and normal (i.e., linear) network analysis cannot be used, the effect must be dealt with separately. There is yet another group, which may be linear but invalidate the assumption in the analysis that capacitance is a constant. Such an example is temperature dependence. Finally, combined parasitic effects such as inherent inductance, resistance, or dielectric losses can exhibit non-uniform behavior at variable frequencies of operation.

Question: What causes the assumption of constant capacitance to fail even if the effect is linear in nature?
Ans:
temperature dependence
