input: Please answer the following: Extract the answer to the question from the following context. Question: What are types of copper minerals? Context: Copper is synthesized in massive stars and is present in the Earth's crust at a concentration of about 50 parts per million (ppm), where it occurs as native copper or in minerals such as the copper sulfides chalcopyrite and chalcocite, the copper carbonates azurite and malachite, and the copper(I) oxide mineral cuprite. The largest mass of elemental copper discovered weighed 420 tonnes and was found in 1857 on the Keweenaw Peninsula in Michigan, US. Native copper is a polycrystal, with the largest described single crystal measuring 4.43.23.2 cm.

output: the copper carbonates azurite and malachite, and the copper(I) oxide mineral cuprite

Please answer this: Extract the answer to the question from the following context. Question: Who were the Hanoverians successful in battling? Context: The year 1759 saw several Prussian defeats. At the Battle of Kay, or Paltzig, the Russian Count Saltykov with 47,000 Russians defeated 26,000 Prussians commanded by General Carl Heinrich von Wedel. Though the Hanoverians defeated an army of 60,000 French at Minden, Austrian general Daun forced the surrender of an entire Prussian corps of 13,000 in the Battle of Maxen. Frederick himself lost half his army in the Battle of Kunersdorf (now Kunowice Poland), the worst defeat in his military career and one that drove him to the brink of abdication and thoughts of suicide. The disaster resulted partly from his misjudgment of the Russians, who had already demonstrated their strength at Zorndorf and at Gross-Jagersdorf (now Motornoye, Russia), and partly from good cooperation between the Russian and Austrian forces.

Problem: Extract the answer to the question from the following context. Question: What happens because of the memory? Context: The storage in sensory memory and short-term memory generally has a strictly limited capacity and duration, which means that information is not retained indefinitely. By contrast, long-term memory can store much larger quantities of information for potentially unlimited duration (sometimes a whole life span). Its capacity is immeasurable. For example, given a random seven-digit number we may remember it for only a few seconds before forgetting, suggesting it was stored in our short-term memory. On the other hand, we can remember telephone numbers for many years through repetition; this information is said to be stored in long-term memory.

A: information is not retained indefinitely

Problem: Given the question: Extract the answer to the question from the following context. Question: Why is DC usually used for bulk power transmission? Context: There has, however, been interest among railroad operators in returning to DC use at higher voltages than previously used. At the same voltage, DC often has less loss than AC, and for this reason high-voltage direct current is already used on some bulk power transmission lines. DC avoids the electromagnetic radiation inherent with AC, and on a railway this also reduces interference with signalling and communications and mitigates hypothetical EMF risks. DC also avoids the power factor problems of AC. Of particular interest to railroading is that DC can supply constant power with a single ungrounded wire. Constant power with AC requires three-phase transmission with at least two ungrounded wires. Another important consideration is that mains-frequency 3-phase AC must be carefully planned to avoid unbalanced phase loads. Parts of the system are supplied from different phases on the assumption that the total loads of the 3 phases will even out. At the phase break points between regions supplied from different phases, long insulated supply breaks are required to avoid them being shorted by rolling stock using more than one pantograph at a time. A few railroads have tried 3-phase but its substantial complexity has made single-phase standard practice despite the interruption in power flow that occurs twice every cycle. An experimental 6 kV DC railway was built in the Soviet Union.

The answer is:
less loss

input question: Extract the answer to the question from the following context. Question: Someone from what culture is in a fountain? Context: There are eleven Renaissance allegorical statues on public fountains in the Old Town. Nearly all the 16th century fountains, except the Zahringer fountain which was created by Hans Hiltbrand, are the work of the Fribourg master Hans Gieng. One of the more interesting fountains is the Kindlifresserbrunnen (Bernese German: Child Eater Fountain but often translated Ogre Fountain) which is claimed to represent a Jew, the Greek god Chronos or a Fastnacht figure that scares disobedient children.???
output answer: Greek

input question: Extract the answer to the question from the following context. Question: What group did they fight? Context: But by the 1940s, many of Boas' anthropologist contemporaries were active in the allied war effort against the "Axis" (Nazi Germany, Fascist Italy, and Imperial Japan). Many served in the armed forces, while others worked in intelligence (for example, Office of Strategic Services and the Office of War Information). At the same time, David H. Price's work on American anthropology during the Cold War provides detailed accounts of the pursuit and dismissal of several anthropologists from their jobs for communist sympathies.???
output answer:
"Axis"
