Input: Article: Brasília is known as a departing point for the practice of unpowered air sports, sports that may be practiced with hang gliding or paragliding wings. Practitioners of such sports reveal that, because of the city's dry weather, the city offers strong thermal winds and great "cloud-streets", which is also the name for a manoeuvre quite appreciated by practitioners. In 2003, Brasília hosted the 14th Hang Gliding World Championship, one of the categories of free flying. In August 2005, the city hosted the 2nd stage of the Brazilian Hang Gliding Championship.

Now answer this question: Why is Brasilia a good place for air sports?

Output: strong thermal winds and great "cloud-streets"


Article: Although its PlayStation predecessors had been very dominant against the competition and were hugely profitable for Sony, PlayStation 3 had an inauspicious start, and Sony chairman and CEO Sir Howard Stringer initially could not convince investors of a turnaround in its fortunes. The PS3 lacked the unique gameplay of the more affordable Wii which became that generation's most successful console in terms of units sold. Furthermore, PS3 had to compete directly with Xbox 360 which had a market head start, and as a result the platform no longer had exclusive titles that the PS2 enjoyed such as the Grand Theft Auto and Final Fantasy series (regarding cross-platform games, Xbox 360 versions were generally considered superior in 2006, although by 2008 the PS3 versions had reached parity or surpassed), and it took longer than expected for PS3 to enjoy strong sales and close the gap with Xbox 360. Sony also continued to lose money on each PS3 sold through 2010, although the redesigned "slim" PS3 has cut these losses since then.

Question: Which cost less in stores: PS3 or Wii?
Ans: Wii


Here is a question about this article: Another theory describes its derivation from a non-Slavic warrior class,:42, 64–66 forming a distinct element known as the Lechici/Lekhi (Lechitów):430 :482 within the ancient Polonic tribal groupings (Indo-European caste systems). This hypothesis states this upper class was not of Slavonic extraction:482 and was of a different origin than the Slavonic peasants (kmiecie; Latin: cmethones):430 :118 over which they ruled.:482 The Szlachta were differentiated from the rural population. The nobleman's sense of distinction led to practices that in later periods would be characterized as racism.:233 The Szlachta were noble in the Aryan sense -- "noble" in contrast to the people over whom they ruled after coming into contact with them.:482 The szlachta traced their descent from Lech/Lekh, who probably founded the Polish kingdom in about the fifth century.:482 Lechia was the name of Poland in antiquity, and the szlachta's own name for themselves was Lechici/Lekhi.:482 An exact counterpart of Szlachta society was the Meerassee system of tenure of southern India—an aristocracy of equality—settled as conquerors among a separate race.:484 The Polish state paralleled the Roman Empire in that full rights of citizenship were limited to the szlachta. The szlachta were a caste, a military caste, as in Hindu society.
What is the answer to this question: In this theory, what was the upper class?
****
So... was of a different origin than the Slavonic peasants


The problem: Answer a question about this article:
A team led by Enrico Fermi in 1934 observed that bombarding uranium with neutrons produces the emission of beta rays (electrons or positrons from the elements produced; see beta particle). The fission products were at first mistaken for new elements of atomic numbers 93 and 94, which the Dean of the Faculty of Rome, Orso Mario Corbino, christened ausonium and hesperium, respectively. The experiments leading to the discovery of uranium's ability to fission (break apart) into lighter elements and release binding energy were conducted by Otto Hahn and Fritz Strassmann in Hahn's laboratory in Berlin. Lise Meitner and her nephew, the physicist Otto Robert Frisch, published the physical explanation in February 1939 and named the process "nuclear fission". Soon after, Fermi hypothesized that the fission of uranium might release enough neutrons to sustain a fission reaction. Confirmation of this hypothesis came in 1939, and later work found that on average about 2.5 neutrons are released by each fission of the rare uranium isotope uranium-235. Further work found that the far more common uranium-238 isotope can be transmuted into plutonium, which, like uranium-235, is also fissile by thermal neutrons. These discoveries led numerous countries to begin working on the development of nuclear weapons and nuclear power.
Who was the aunt of Otto Robert Frisch?
****
The answer: Lise Meitner


Problem: Please answer a question about the following article about Age of Enlightenment:
Intellectuals such as Robert Darnton and Jürgen Habermas have focused on the social conditions of the Enlightenment. Habermas described the creation of the "bourgeois public sphere" in 18th-century Europe, containing the new venues and modes of communication allowing for rational exchange. Habermas said that the public sphere was bourgeois, egalitarian, rational, and independent from the state, making it the ideal venue for intellectuals to critically examine contemporary politics and society, away from the interference of established authority. While the public sphere is generally an integral component of the social study of the Enlightenment, other historians have questioned whether the public sphere had these characteristics.
How did Habermas describe the public sphere?
A: bourgeois, egalitarian, rational, and independent from the state


Question: Read this and answer the question

During the reign of Khārabēḷa, the Chedi dynasty of Kaḷinga ascended to eminence and restored the lost power and glory of Kaḷinga, which had been subdued since the devastating war with Ashoka. Kaḷingan military might was reinstated by Khārabēḷa: under Khārabēḷa's generalship, the Kaḷinga state had a formidable maritime reach with trade routes linking it to the then-Simhala (Sri Lanka), Burma (Myanmar), Siam (Thailand), Vietnam, Kamboja (Cambodia), Malaysia, Borneo, Bali, Samudra (Sumatra) and Jabadwipa (Java). Khārabēḷa led many successful campaigns against the states of Magadha, Anga, Satavahanas till the southern most regions of Pandyan Empire (modern Tamil Nadu).

What militaristic leader restored might to the Kalinga empire?
Answer:
Khārabēḷa
