Problem: Please answer a question about the following article about MP3:
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]
The need to code excess energy in the frequency domain decreases what kind of efficiency?
A: coding

Zinc deficiency is crop plants' most common micronutrient deficiency; it is particularly common in high-pH soils. Zinc-deficient soil is cultivated in the cropland of about half of Turkey and India, a third of China, and most of Western Australia, and substantial responses to zinc fertilization have been reported in these areas. Plants that grow in soils that are zinc-deficient are more susceptible to disease. Zinc is primarily added to the soil through the weathering of rocks, but humans have added zinc through fossil fuel combustion, mine waste, phosphate fertilizers, pesticide (zinc phosphide), limestone, manure, sewage sludge, and particles from galvanized surfaces. Excess zinc is toxic to plants, although zinc toxicity is far less widespread.

In what type of soil is zinc deficiency most common?
Answer: high-pH soils

Problem: Brasilia has a tropical savanna climate (Aw) according to the Koppen system, with two distinct seasons: the rainy season, from October to April, and a dry season, from May to September. The average temperature is 20.6 C (69.1 F). September, at the end of the dry season, has the highest average maximum temperature, 28.3 C (82.9 F), has major and minor lower maximum average temperature, of 25.1 C (77.2 F) and 12.9 C (55.2 F), respectively. Average temperatures from September through March are a consistent 22 C (72 F). With 247.4 mm (9.7 in), January is the month with the highest rainfall of the year, while June is the lowest, with only 8.7 mm (0.3 in).
When is Brasilia's rainy season?
The answer is the following: October to April

The Palacio Taranco is located in front of the Plaza Zabala, in the heart of Ciudad Vieja. It was erected in the early 20th century as the residence of the Ortiz Taranco brothers on the ruins of Montevideo's first theatre (of 1793), during a period in which the architectural style was influenced by French architecture. The palace was designed by French architects Charles Louis Girault and Jules Chifflot Leon who also designed the Petit Palais and the Arc de Triomphe in Paris. It passed to the city from the heirs of the Tarancos in 1943, along with its precious collection of Uruguayan furniture and draperies and was deemed by the city as an ideal place for a museum; in 1972 it became the Museum of Decorative Arts of Montevideo and in 1975 it became a National Heritage Site. The Decorative Arts Museum has an important collection of European paintings and decorative arts, ancient Greek and Roman art and Islamic ceramics of the 10th18th century from the area of present-day Iran. The palace is often used as a meeting place by the Uruguayan government.
Where is the Palacio Taranco located?
the heart of Ciudad Vieja

Input: Windows 8
Reviews of the various editions of Windows 8 have been mixed. Tom Warren of The Verge said that although Windows 8's emphasis on touch computing was significant and risked alienating desktop users, a "tablet PC with Windows 8 makes an iPad feel immediately out of date" due to the capabilities of the operating system's hybrid model and increased focus on cloud services. David Pierce of The Verge described Windows 8 as "the first desktop operating system that understands what a computer is supposed to do in 2012" and praised Microsoft's "no compromise" approach and the operating system's emphasis on Internet connectivity and cloud services. Pierce also considered the Start Screen to be a "brilliant innovation for desktop computers" when compared with "folder-littered desktops on every other OS" because it allows users to interact with dynamic information. In contrast, an ExtremeTech article said it was Microsoft "flailing" and a review in PC Magazine condemned the Metro-style user interface. Some of the included apps in Windows 8 were considered to be basic and lacking in functionality, but the Xbox apps were praised for their promotion of a multi-platform entertainment experience. Other improvements and features (such as File History, Storage Spaces, and the updated Task Manager) were also regarded as positive changes. Peter Bright of Ars Technica wrote that while its user interface changes may overshadow them, Windows 8's improved performance, updated file manager, new storage functionality, expanded security features, and updated Task Manager were still positive improvements for the operating system. Bright also said that Windows 8's duality towards tablets and traditional PCs was an "extremely ambitious" aspect of the platform as well, but criticized Microsoft for emulating Apple's model of a closed distribution platform when implementing the Windows Store.

Why did Pierce give the Start Screen such glowing reviews?
Output: because it allows users to interact with dynamic information

Problem: Please answer a question about the following article about Emotion:
Robert Plutchik agreed with Ekman's biologically driven perspective but developed the "wheel of emotions", suggesting eight primary emotions grouped on a positive or negative basis: joy versus sadness; anger versus fear; trust versus disgust; and surprise versus anticipation. Some basic emotions can be modified to form complex emotions. The complex emotions could arise from cultural conditioning or association combined with the basic emotions. Alternatively, similar to the way primary colors combine, primary emotions could blend to form the full spectrum of human emotional experience. For example, interpersonal anger and disgust could blend to form contempt. Relationships exist between basic emotions, resulting in positive or negative influences.
What does Plutchik see as the positive equivalent of disgust?
A:
trust
