Problem: Please answer a question about the following article about Frederic Chopin:
Fryderyk may have had some piano instruction from his mother, but his first professional music tutor, from 1816 to 1821, was the Czech pianist Wojciech Zywny. His elder sister Ludwika also took lessons from Zywny, and occasionally played duets with her brother. It quickly became apparent that he was a child prodigy. By the age of seven Fryderyk had begun giving public concerts, and in 1817 he composed two polonaises, in G minor and B-flat major. His next work, a polonaise in A-flat major of 1821, dedicated to Zywny, is his earliest surviving musical manuscript.
What year did Chopin compose his first work?
A: 1817

The city shares a 15-mile (24 km) border with Mexico that includes two border crossings. San Diego hosts the busiest international border crossing in the world, in the San Ysidro neighborhood at the San Ysidro Port of Entry. A second, primarily commercial border crossing operates in the Otay Mesa area; it is the largest commercial crossing on the California-Baja California border and handles the third-highest volume of trucks and dollar value of trade among all United States-Mexico land crossings.
How many border crossings does San Diego share with Mexico?
A: two
Problem: Please answer a question about the following article about Szlachta:
Nobles were born into a noble family, adopted by a noble family (this was abolished in 1633) or ennobled by a king or Sejm for various reasons (bravery in combat, service to the state, etc.yet this was the rarest means of gaining noble status). Many nobles were, in actuality, really usurpers, being commoners, who moved into another part of the country and falsely pretended to noble status. Hundreds of such false nobles were denounced by Hieronim Nekanda Trepka in his Liber generationis plebeanorium (or Liber chamorum) in the first half of the 16th century. The law forbade non-nobles from owning nobility-estates and promised the estate to the denouncer. Trepka was an impoverished nobleman who lived a townsman life and collected hundreds of such stories hoping to take over any of such estates. It does not seem he ever succeeded in proving one at the court. Many sejms issued decrees over the centuries in an attempt to resolve this issue, but with little success. It is unknown what percentage of the Polish nobility came from the 'lower' orders of society, but most historians agree that nobles of such base origins formed a 'significant' element of the szlachta.
What was a rarest rare to become a noble?
A: service to the state
Problem: Please answer a question about the following article about Race (human categorization):
According to the 2000 edition of a popular physical anthropology textbook, forensic anthropologists are overwhelmingly in support of the idea of the basic biological reality of human races. Forensic physical anthropologist and professor George W. Gill has said that the idea that race is only skin deep "is simply not true, as any experienced forensic anthropologist will affirm" and "Many morphological features tend to follow geographic boundaries coinciding often with climatic zones. This is not surprising since the selective forces of climate are probably the primary forces of nature that have shaped human races with regard not only to skin color and hair form but also the underlying bony structures of the nose, cheekbones, etc. (For example, more prominent noses humidify air better.)" While he can see good arguments for both sides, the complete denial of the opposing evidence "seems to stem largely from socio-political motivation and not science at all". He also states that many biological anthropologists see races as real yet "not one introductory textbook of physical anthropology even presents that perspective as a possibility. In a case as flagrant as this, we are not dealing with science but rather with blatant, politically motivated censorship".
What does Gill think the complete denial of opposing evidence stems from?
A:
socio-political motivation
