Although the number of base-pairs of DNA in the human genome has been known since the 1960s, the estimated number of genes has changed over time as definitions of genes, and methods of detecting them have been refined. Initial theoretical predictions of the number of human genes were as high as 2,000,000. Early experimental measures indicated there to be 50,000–100,000 transcribed genes (expressed sequence tags). Subsequently, the sequencing in the Human Genome Project indicated that many of these transcripts were alternative variants of the same genes, and the total number of protein-coding genes was revised down to ~20,000 with 13 genes encoded on the mitochondrial genome. Of the human genome, only 1–2% consists of protein-coding genes, with the remainder being 'noncoding' DNA such as introns, retrotransposons, and noncoding RNAs.
Since when has the number of base pairs of DNA in the human genome been known?
the 1960s


Input: Muslim world
Theologus Autodidactus, written by the Arabian polymath Ibn al-Nafis (1213–1288), is the first example of a science fiction novel. It deals with various science fiction elements such as spontaneous generation, futurology, the end of the world and doomsday, resurrection, and the afterlife. Rather than giving supernatural or mythological explanations for these events, Ibn al-Nafis attempted to explain these plot elements using the scientific knowledge of biology, astronomy, cosmology and geology known in his time. Ibn al-Nafis' fiction explained Islamic religious teachings via science and Islamic philosophy.

What was the life span of Ibn al-Nafis?
Output: 1213–1288


Input: Article: Kublai Khan did not conquer the Song dynasty in South China until 1279, so Tibet was a component of the early Mongol Empire before it was combined into one of its descendant empires with the whole of China under the Yuan dynasty (1271–1368). Van Praag writes that this conquest "marked the end of independent China," which was then incorporated into the Yuan dynasty that ruled China, Tibet, Mongolia, Korea, parts of Siberia and Upper Burma. Morris Rossabi, a professor of Asian history at Queens College, City University of New York, writes that "Khubilai wished to be perceived both as the legitimate Khan of Khans of the Mongols and as the Emperor of China. Though he had, by the early 1260s, become closely identified with China, he still, for a time, claimed universal rule", and yet "despite his successes in China and Korea, Khubilai was unable to have himself accepted as the Great Khan". Thus, with such limited acceptance of his position as Great Khan, Kublai Khan increasingly became identified with China and sought support as Emperor of China.

Now answer this question: Where did Khubilai seek support as Emperor?

Output: China


Article: Urban heat islands (UHI) are metropolitan areas with higher temperatures than that of the surrounding environment. The higher temperatures are a result of increased absorption of the Solar light by urban materials such as asphalt and concrete, which have lower albedos and higher heat capacities than those in the natural environment. A straightforward method of counteracting the UHI effect is to paint buildings and roads white and plant trees. Using these methods, a hypothetical "cool communities" program in Los Angeles has projected that urban temperatures could be reduced by approximately 3 °C at an estimated cost of US$1 billion, giving estimated total annual benefits of US$530 million from reduced air-conditioning costs and healthcare savings.

Question: What are the metropolitan areas with higher temperatures than the surrounding areas called?
Ans: Urban heat islands


Here is a question about this article: In European history, the Middle Ages or medieval period lasted from the 5th to the 15th century. It began with the collapse of the Western Roman Empire and merged into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: Antiquity, Medieval period, and Modern period. The Medieval period is itself subdivided into the Early, the High, and the Late Middle Ages.
What is the answer to this question: What event marked the beginning of the Middle Ages?
****
So... the collapse of the Western Roman Empire


Article: Greek colonies and communities have been historically established on the shores of the Mediterranean Sea and Black Sea, but the Greek people have always been centered around the Aegean and Ionian seas, where the Greek language has been spoken since the Bronze Age. Until the early 20th century, Greeks were distributed between the Greek peninsula, the western coast of Asia Minor, the Black Sea coast, Cappadocia in central Anatolia, Egypt, the Balkans, Cyprus, and Constantinople. Many of these regions coincided to a large extent with the borders of the Byzantine Empire of the late 11th century and the Eastern Mediterranean areas of ancient Greek colonization. The cultural centers of the Greeks have included Athens, Thessalonica, Alexandria, Smyrna, and Constantinople at various periods.

Question: Which two bodies of water are believed to be central to the establishment of the Greek society ?
Ans:
Greek people have always been centered around the Aegean and Ionian seas
