Input: Read this: The native language of Germans is German, a West Germanic language, related to and classified alongside English and Dutch, and sharing many similarities with the North Germanic and Scandinavian languages. Spoken by approximately 100 million native speakers, German is one of the world's major languages and the most widely spoken first language in the European Union. German has been replaced by English as the dominant language of science-related Nobel Prize laureates during the second half of the 20th century. It was a lingua franca in the Holy Roman Empire.
Question: How many people speak German around the world?

Output: unanswerable

Input: Read this: The remote location of the islands makes transport to the outside world difficult. Lacking an airport, the islands can be reached only by sea. Fishing boats from South Africa service the islands eight or nine times a year. The RMS Saint Helena used to connect the main island to St Helena and South Africa once each year during its January voyage, but has done so only twice in the last few years, in 2006 and 2011. The wider territory has access to air travel with Ascension island served by RAF Ascension Island and a new airport, financed by the United Kingdom government, under construction on St Helena and due for completion in 2016. There is however no direct, regular service to Tristan da Cunha itself from either location. The harbour at Edinburgh of the Seven Seas is called Calshot Harbour, named after the place in Hampshire where the islanders temporarily stayed during the volcanic eruption.
Question: Lacking a sea, how can the islands be reached?

Output: unanswerable

Input: Read this: Cork was originally a monastic settlement, reputedly founded by Saint Finbarr in the 6th century. Cork achieved an urban character at some point between 915 and 922 when Norseman (Viking) settlers founded a trading port. It has been proposed that, like Dublin, Cork was an important trading centre in the global Scandinavian trade network. The ecclesiastical settlement continued alongside the Viking longphort, with the two developing a type of symbiotic relationship; the Norsemen providing otherwise unobtainable trade goods for the monastery, and perhaps also military aid.
Question: What kind of settlement was Dublin originally?

Output: unanswerable

Input: Read this: Psychoactive drugs can impair the judgment of time. Stimulants can lead both humans and rats to overestimate time intervals, while depressants can have the opposite effect. The level of activity in the brain of neurotransmitters such as dopamine and norepinephrine may be the reason for this. Such chemicals will either excite or inhibit the firing of neurons in the brain, with a greater firing rate allowing the brain to register the occurrence of more events within a given interval (speed up time) and a decreased firing rate reducing the brain's capacity to distinguish events occurring within a given interval (slow down time).
Question: What does the presence of neurons impair the judgement of in rats?
