Question: I know that the answer to the question "Why was a song created?" is in "An Ancient Chinese document from the 9th century referred to the northern Somali coast which was then called "Berbera" by Arab geographers in reference to the region's "Berber" (Cushitic) inhabitants as Po-pa-li. The first clear written reference of the sobriquet Somali, however, dates back to the 15th century. During the wars between the Sultanate of Ifat based at Zeila and the Solomonic Dynasty, the Abyssinian Emperor had one of his court officials compose a hymn celebrating a military victory over the Sultan of Ifat's eponymous troops.". Can you tell me what it is?
Answer: military victory

[Q]: I know that the answer to the question "What be subject ot dofferent levels of pressure?" is in "Hydrostatic gauges (such as the mercury column manometer) consist of a vertical column of liquid in a tube whose ends are exposed to different pressures. The column will rise or fall until its weight is in equilibrium with the pressure differential between the two ends of the tube. The simplest design is a closed-end U-shaped tube, one side of which is connected to the region of interest. Any fluid can be used, but mercury is preferred for its high density and low vapour pressure. Simple hydrostatic gauges can measure pressures ranging from 1 torr (100 Pa) to above atmospheric. An important variation is the McLeod gauge which isolates a known volume of vacuum and compresses it to multiply the height variation of the liquid column. The McLeod gauge can measure vacuums as high as 106 torr (0.1 mPa), which is the lowest direct measurement of pressure that is possible with current technology. Other vacuum gauges can measure lower pressures, but only indirectly by measurement of other pressure-controlled properties. These indirect measurements must be calibrated via a direct measurement, most commonly a McLeod gauge.". Can you tell me what it is?

input: Please answer the following: I know that the answer to the question "If a goose were feeling tired in the sky, how would it want to avoid traveling?" is in "Many, if not most, birds migrate in flocks. For larger birds, flying in flocks reduces the energy cost. Geese in a V-formation may conserve 1220% of the energy they would need to fly alone. Red knots Calidris canutus and dunlins Calidris alpina were found in radar studies to fly 5 km/h (3.1 mph) faster in flocks than when they were flying alone.". Can you tell me what it is?

output: fly alone

Please answer this: I know that the answer to the question "What is notable about these films?" is in "Some high-speed black-and-white films, such as Ilford Delta 3200 and Kodak T-MAX P3200, are marketed with film speeds in excess of their true ISO speed as determined using the ISO testing method. For example, the Ilford product is actually an ISO 1000 film, according to its data sheet. The manufacturers do not indicate that the 3200 number is an ISO rating on their packaging. Kodak and Fuji also marketed E6 films designed for pushing (hence the "P" prefix), such as Ektachrome P800/1600 and Fujichrome P1600, both with a base speed of ISO 400.". Can you tell me what it is?

Answer: marketed with film speeds in excess of their true ISO speed as determined using the ISO testing method

Problem: I know that the answer to the question "What country was the largest competitor in the global market?" is in "With the advent of the Industrial Revolution, Britain surged ahead of its European rivals. Demand for Indian commodities was boosted by the need to sustain the troops and the economy during the war, and by the increased availability of raw materials and efficient methods of production. As home to the revolution, Britain experienced higher standards of living. Its spiralling cycle of prosperity, demand and production had a profound influence on overseas trade. The company became the single largest player in the British global market. William Henry Pyne notes in his book The Microcosm of London (1808) that:". Can you tell me what it is?

A: Britain

input: Please answer the following: I know that the answer to the question "Words with a common etymology such as the English actual and the French actuel are known as what?" is in "Generally, the greater the contact and exchange that have existed between two languages, or between those languages and a third one, the greater is the ratio of metaphrase to paraphrase that may be used in translating among them. However, due to shifts in ecological niches of words, a common etymology is sometimes misleading as a guide to current meaning in one or the other language. For example, the English actual should not be confused with the cognate French actuel ("present", "current"), the Polish aktualny ("present", "current," "topical," "timely," "feasible"), the Swedish aktuell ("topical", "presently of importance"), the Russian ("urgent", "topical") or the Dutch actueel.". Can you tell me what it is?

output:
cognate
