Problem: Please answer a question about the following article about Antenna (radio):
Antenna tuning generally refers to cancellation of any reactance seen at the antenna terminals, leaving only a resistive impedance which might or might not be exactly the desired impedance (that of the transmission line). Although an antenna may be designed to have a purely resistive feedpoint impedance (such as a dipole 97% of a half wavelength long) this might not be exactly true at the frequency that it is eventually used at. In some cases the physical length of the antenna can be "trimmed" to obtain a pure resistance. On the other hand, the addition of a series inductance or parallel capacitance can be used to cancel a residual capacitative or inductive reactance, respectively.
What can be used to cancel a inductibe reactance or residual capacitative?
A: parallel capacitance
Problem: Please answer a question about the following article about European Central Bank:
Rescue operations involving sovereign debt have included temporarily moving bad or weak assets off the balance sheets of the weak member banks into the balance sheets of the European Central Bank. Such action is viewed as monetisation and can be seen as an inflationary threat, whereby the strong member countries of the ECB shoulder the burden of monetary expansion (and potential inflation) to save the weak member countries. Most central banks prefer to move weak assets off their balance sheets with some kind of agreement as to how the debt will continue to be serviced. This preference has typically led the ECB to argue that the weaker member countries must:
What is monetisation usually viewed as?
A: inflationary threat
Problem: Please answer a question about the following article about Guinea-Bissau:
Malaria kills more residents; 9% of the population have reported infection, It causes three times as many deaths as AIDS. In 2008, fewer than half of children younger than five slept under antimalaria nets or had access to antimalarial drugs.
What percentage of the population has Malaria?
A: 9%
Problem: Please answer a question about the following article about Beyonce:
Beyonce's lighter skin color and costuming has drawn criticism from some in the African-American community. Emmett Price, a professor of music at Northeastern University, wrote in 2007, that he thinks race plays a role in many of these criticisms, saying white celebrities who dress similarly do not attract as many comments. In 2008, L'Oreal was accused of whitening her skin in their Feria hair color advertisements, responding that "it is categorically untrue", and in 2013, Beyonce herself criticized H&M for their proposed "retouching" of promotional images of her, and according to Vogue requested that only "natural pictures be used".
What advertisement was Beyonce's skin supposedly lightened in?
A:
Feria hair color advertisements
