Input: History of science
The synthesis of urea by Friedrich Wohler opened a new research field, organic chemistry, and by the end of the 19th century, scientists were able to synthesize hundreds of organic compounds. The later part of the 19th century saw the exploitation of the Earth's petrochemicals, after the exhaustion of the oil supply from whaling. By the 20th century, systematic production of refined materials provided a ready supply of products which provided not only energy, but also synthetic materials for clothing, medicine, and everyday disposable resources. Application of the techniques of organic chemistry to living organisms resulted in physiological chemistry, the precursor to biochemistry. The 20th century also saw the integration of physics and chemistry, with chemical properties explained as the result of the electronic structure of the atom. Linus Pauling's book on The Nature of the Chemical Bond used the principles of quantum mechanics to deduce bond angles in ever-more complicated molecules. Pauling's work culminated in the physical modelling of DNA, the secret of life (in the words of Francis Crick, 1953). In the same year, the MillerUrey experiment demonstrated in a simulation of primordial processes, that basic constituents of proteins, simple amino acids, could themselves be built up from simpler molecules.

What scientific act is Friedrich Wohler known for?

Input: Article: In 1939, coinciding with the start of World War II, Rene Dubos reported the discovery of the first naturally derived antibiotic, tyrothricin, a compound of 20% gramicidin and 80% tyrocidine, from B. brevis. It was one of the first commercially manufactured antibiotics universally and was very effective in treating wounds and ulcers during World War II. Gramicidin, however, could not be used systemically because of toxicity. Tyrocidine also proved too toxic for systemic usage. Research results obtained during that period were not shared between the Axis and the Allied powers during the war.

Now answer this question: Who discovered tyrothricin?

Output: Rene Dubos

Article: The basic annelid form consists of multiple segments. Each segment has the same sets of organs and, in most polychaetes, has a pair of parapodia that many species use for locomotion. Septa separate the segments of many species, but are poorly defined or absent in others, and Echiura and Sipuncula show no obvious signs of segmentation. In species with well-developed septa, the blood circulates entirely within blood vessels, and the vessels in segments near the front ends of these species are often built up with muscles that act as hearts. The septa of such species also enable them to change the shapes of individual segments, which facilitates movement by peristalsis ("ripples" that pass along the body) or by undulations that improve the effectiveness of the parapodia. In species with incomplete septa or none, the blood circulates through the main body cavity without any kind of pump, and there is a wide range of locomotory techniques some burrowing species turn their pharynges inside out to drag themselves through the sediment.

Question: What separates many annelids' segments?
Ans: Septa

Here is a question about this article: Its average annual temperature is 18.4 C (65.1 F). 22.8 C (73.0 F) during the day and 13.8 C (56.8 F) at night. In the coldest month January, the maximum temperature typically during the day ranges from 13 to 21 C (55 to 70 F), the minimum temperature typically at night ranges from 4 to 12 C (39 to 54 F). In the warmest month August, the maximum temperature during the day typically ranges from 2834 C (8293 F), about 23 C (73 F) at night. Generally, temperatures similar to those experienced in the northern part of Europe in summer last about 8 months, from April to November. March is transitional, the temperature often exceeds 20 C (68 F), with an average temperature of 19.0 C (66 F) during the day and 10.0 C (50 F) at night. December, January and February are the coldest months, with average temperatures around 17 C (63 F) during the day and 7 C (45 F) at night. Valencia has one of the mildest winters in Europe, owing to its southern location on the Mediterranean Sea and the Foehn phenomenon. The January average is comparable to temperatures expected for May and September in the major cities of northern Europe.
What is the answer to this question: What is Valencia's average yearly temperature?
****
So... 18.4 C

The problem: Answer a question about this article:
The primary site of infection in the lungs, known as the "Ghon focus", is generally located in either the upper part of the lower lobe, or the lower part of the upper lobe. Tuberculosis of the lungs may also occur via infection from the blood stream. This is known as a Simon focus and is typically found in the top of the lung. This hematogenous transmission can also spread infection to more distant sites, such as peripheral lymph nodes, the kidneys, the brain, and the bones. All parts of the body can be affected by the disease, though for unknown reasons it rarely affects the heart, skeletal muscles, pancreas, or thyroid.
If the lungs are infected by TB via bloodstream, what's the type of focus?
****
The answer: Simon focus

The problem: Answer a question about this article:
Kathmandu is dissected by eight rivers, the main river of the valley, the Bagmati and its tributaries, of which the Bishnumati, Dhobi Khola, Manohara Khola, Hanumant Khola, and Tukucha Khola are predominant. The mountains from where these rivers originate are in the elevation range of 1,5003,000 metres (4,9009,800 ft), and have passes which provide access to and from Kathmandu and its valley. An ancient canal once flowed from Nagarjuna hill through Balaju to Kathmandu; this canal is now extinct.
Where did the canal that once terminated in Kathmandu originate?
****
The answer:
Nagarjuna hill
