Problem: Please answer a question about the following article about Chinese characters:
The earliest confirmed evidence of the Chinese script yet discovered is the body of inscriptions on oracle bones from the late Shang dynasty (c. 12001050 BC). These symbols, carved on pieces of bone and turtle shell being sold as "dragon bones" for medicinal purposes, were identified as Chinese writing by scholars in 1899. By 1928, the source of the oracle bones had been traced to a village near Anyang in Henan Province, which was excavated by the Academia Sinica between 1928 and 1937. Over 150,000 fragments have been found.
What was the earliest confirmed evidence of the Chinese script?
A: oracle bones
Problem: Please answer a question about the following article about LaserDisc:
LaserDisc was a composite video format: the luminance (black and white) and chrominance (color) information were transmitted in one signal, separated by the receiver. While good comb filters can do so adequately, these two signals cannot be completely separated. On DVDs, data is stored in the form of digital blocks which make up each independent frame. The signal produced is dependent on the equipment used to master the disc. Signals range from composite and split, to YUV and RGB. Depending upon which format is used, this can result in far higher fidelity, particularly at strong color borders or regions of high detail (especially if there is moderate movement in the picture) and low-contrast details like skin tones, where comb filters almost inevitably smudge some detail.
In what areas are comb filters most likely to lose detail?
A: low-contrast details like skin tones
Problem: Please answer a question about the following article about Empiricism:
The decidedly anti-Aristotelian and anti-clerical music theorist Vincenzo Galilei (ca. 15201591), father of Galileo and the inventor of monody, made use of the method in successfully solving musical problems, firstly, of tuning such as the relationship of pitch to string tension and mass in stringed instruments, and to volume of air in wind instruments; and secondly to composition, by his various suggestions to composers in his Dialogo della musica antica e moderna (Florence, 1581). The Italian word he used for "experiment" was esperienza. It is known that he was the essential pedagogical influence upon the young Galileo, his eldest son (cf. Coelho, ed. Music and Science in the Age of Galileo Galilei), arguably one of the most influential empiricists in history. Vincenzo, through his tuning research, found the underlying truth at the heart of the misunderstood myth of 'Pythagoras' hammers' (the square of the numbers concerned yielded those musical intervals, not the actual numbers, as believed), and through this and other discoveries that demonstrated the fallibility of traditional authorities, a radically empirical attitude developed, passed on to Galileo, which regarded "experience and demonstration" as the sine qua non of valid rational enquiry.
When did Vincenzo Galilei die?
A: 1591
Problem: Please answer a question about the following article about Gene:
Genes with a most recent common ancestor, and thus a shared evolutionary ancestry, are known as homologs. These genes appear either from gene duplication within an organism's genome, where they are known as paralogous genes, or are the result of divergence of the genes after a speciation event, where they are known as orthologous genes,:7.6 and often perform the same or similar functions in related organisms. It is often assumed that the functions of orthologous genes are more similar than those of paralogous genes, although the difference is minimal.
What is one reason for homologs to appear?
A:
gene duplication within an organism's genome
