Input: Read this: Weather and climate in the coastal area are dominated by the cold, north-flowing Benguela current of the Atlantic Ocean which accounts for very low precipitation (50 mm per year or less), frequent dense fog, and overall lower temperatures than in the rest of the country. In Winter, occasionally a condition known as Bergwind (German: Mountain breeze) or Oosweer (Afrikaans: East weather) occurs, a hot dry wind blowing from the inland to the coast. As the area behind the coast is a desert, these winds can develop into sand storms with sand deposits in the Atlantic Ocean visible on satellite images.
Question: What is the German expression for Oosweer?

Output: unanswerable


QUES: In most cases, the non-penalized team will have the option of declining the penalty; in which case the results of the previous play stand as if the penalty had not been called. One notable exception to this rule is if the kicking team on a 3rd down punt play is penalized before the kick occurs: the receiving team may not decline the penalty and take over on downs. After the kick is made, change of possession occurs and subsequent penalties are assessed against either the spot where the ball is caught, or the runback.

What is an exception to the change of possession for the non-penalized team?
What is the answer?
ANS: unanswerable


QUES: The Greco-Egyptian scientist Claudius Ptolemy referred to the larger island as great Britain (μεγάλης Βρεττανίας - megális Brettanias) and to Ireland as little Britain (μικρής Βρεττανίας - mikris Brettanias) in his work Almagest (147–148 AD). In his later work, Geography (c. 150 AD), he gave these islands the names Alwion, Iwernia, and Mona (the Isle of Man), suggesting these may have been names of the individual islands not known to him at the time of writing Almagest. The name Albion appears to have fallen out of use sometime after the Roman conquest of Great Britain, after which Britain became the more commonplace name for the island called Great Britain.
What did Claudis Ptolemy write in the 1st century AD

Declarative memory can be further sub-divided into semantic memory, concerning principles and facts taken independent of context; and episodic memory, concerning information specific to a particular context, such as a time and place. Semantic memory allows the encoding of abstract knowledge about the world, such as "Paris is the capital of France". Episodic memory, on the other hand, is used for more personal memories, such as the sensations, emotions, and personal associations of a particular place or time. Episodic memories often reflect the "firsts" in life such as a first kiss, first day of school or first time winning a championship. These are key events in one's life that can be remembered clearly. Autobiographical memory - memory for particular events within one's own life - is generally viewed as either equivalent to, or a subset of, episodic memory. Visual memory is part of memory preserving some characteristics of our senses pertaining to visual experience. One is able to place in memory information that resembles objects, places, animals or people in sort of a mental image. Visual memory can result in priming and it is assumed some kind of perceptual representational system underlies this phenomenon.[citation needed]
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Which type of memory disables us to remember knowledge of the world?
Ah, so.. unanswerable


Question: While Göring was optimistic the Luftwaffe could prevail, Hitler was not. On 17 September he postponed Operation Sea Lion (as it turned out, indefinitely) rather than gamble Germany's newly gained military prestige on a risky cross-Channel operation, particularly in the face of a sceptical Joseph Stalin in the Soviet Union. In the last days of the battle, the bombers became lures in an attempt to draw the RAF into combat with German fighters. But their operations were to no avail; the worsening weather and unsustainable attrition in daylight gave the OKL an excuse to switch to night attacks on 7 October.
Try to answer this question if possible: When did the OKL switch to night raids?
Answer: 7 October


Input: Read this: Software faults occur through the following processes. A programmer makes an error (mistake), which results in a defect (fault, bug) in the software source code. If this defect is executed, in certain situations the system will produce wrong results, causing a failure. Not all defects will necessarily result in failures. For example, defects in dead code will never result in failures. A defect can turn into a failure when the environment is changed. Examples of these changes in environment include the software being run on a new computer hardware platform, alterations in source data, or interacting with different software. A single defect may result in a wide range of failure symptoms.
Question: When can software defects in dead code cause problems?

Output:
run on a new computer hardware platform
