Article: Due to the tree structure of the filter bank, pre-echo problems are made worse, as the combined impulse response of the two filter banks does not, and cannot, provide an optimum solution in time/frequency resolution. Additionally, the combining of the two filter banks' outputs creates aliasing problems that must be handled partially by the "aliasing compensation" stage; however, that creates excess energy to be coded in the frequency domain, thereby decreasing coding efficiency.[citation needed]

Question: What kind of resolution are the filter banks unable to provide an optimal solution for?
Ans: time/frequency

Article: In 1978, Sewall Wright suggested that human populations that have long inhabited separated parts of the world should, in general, be considered different subspecies by the usual criterion that most individuals of such populations can be allocated correctly by inspection. Wright argued that it does not require a trained anthropologist to classify an array of Englishmen, West Africans, and Chinese with 100% accuracy by features, skin color, and type of hair despite so much variability within each of these groups that every individual can easily be distinguished from every other. However, it is customary to use the term race rather than subspecies for the major subdivisions of the human species as well as for minor ones.

Question: How should populations long inhabiting separate parts of the world be considered?
Ans: different subspecies

Article: Innocent gave some dispensations as the crisis progressed. Monastic communities were allowed to celebrate Mass in private from 1209 onwards, and late in 1212 the Holy Viaticum for the dying was authorised. The rules on burials and lay access to churches appear to have been steadily circumvented, at least unofficially. Although the interdict was a burden to much of the population, it did not result in rebellion against John. By 1213, though, John was increasingly worried about the threat of French invasion. Some contemporary chroniclers suggested that in January Philip II of France had been charged with deposing John on behalf of the papacy, although it appears that Innocent merely prepared secret letters in case Innocent needed to claim the credit if Philip did successfully invade England.

Question: When was the Holy Viaticum for the dying authorised?
Ans: 1212

Article: Patronage refers to favoring supporters, for example with government employment. This may be legitimate, as when a newly elected government changes the top officials in the administration in order to effectively implement its policy. It can be seen as corruption if this means that incompetent persons, as a payment for supporting the regime, are selected before more able ones. In nondemocracies many government officials are often selected for loyalty rather than ability. They may be almost exclusively selected from a particular group (for example, Sunni Arabs in Saddam Hussein's Iraq, the nomenklatura in the Soviet Union, or the Junkers in Imperial Germany) that support the regime in return for such favors. A similar problem can also be seen in Eastern Europe, for example in Romania, where the government is often accused of patronage (when a new government comes to power it rapidly changes most of the officials in the public sector).

Question: Giving government jobs to supporters is called what?
Ans:
Patronage
