Input: Read this: The Czech dialects spoken in Moravia and Silesia are known as Moravian (moravština). In the Austro-Hungarian Empire, "Bohemian-Moravian-Slovak" was a language citizens could register as speaking (with German, Polish and several others). Of the Czech dialects, only Moravian is distinguished in nationwide surveys by the Czech Statistical Office. As of 2011, 62,908 Czech citizens spoke Moravian as their first language and 45,561 were diglossal (speaking Moravian and standard Czech as first languages).
Question: How many Czech citizens spoke German as their first language in 2011?

Output: unanswerable


QUES: In the US, one kilowatt-hour (3.6 MJ) of electricity currently causes an average 1.34 pounds (610 g) of CO
2 emission. Assuming the average light bulb is on for 10 hours a day, a 40-watt bulb will cause 196 pounds (89 kg) of CO
2 emission per year. The 6-watt LED equivalent will only cause 30 pounds (14 kg) of CO
2 over the same time span. A building’s carbon footprint from lighting can therefore be reduced by 85% by exchanging all incandescent bulbs for new LEDs if a building previously used only incandescent bulbs.

How much can a building's carbon footprint be reduced by switching to non-LEDs?
What is the answer?
ANS: unanswerable


QUES: The first favours a primordialist approach which takes the sense of self and belonging to a collective group as a fixed thing, defined by objective criteria such as common ancestry and common biological characteristics. The second, rooted in social constructionist theory, takes the view that identity is formed by a predominantly political choice of certain characteristics. In so doing, it questions the idea that identity is a natural given, characterised by fixed, supposedly objective criteria. Both approaches need to be understood in their respective political and historical contexts, characterised by debate on issues of class, race and ethnicity. While they have been criticized, they continue to exert an influence on approaches to the conceptualisation of identity today.
What theory says that political choice is based on identity characteristics?

People with long-term pain frequently display psychological disturbance, with elevated scores on the Minnesota Multiphasic Personality Inventory scales of hysteria, depression and hypochondriasis (the "neurotic triad"). Some investigators have argued that it is this neuroticism that causes acute pain to turn chronic, but clinical evidence points the other way, to chronic pain causing neuroticism. When long-term pain is relieved by therapeutic intervention, scores on the neurotic triad and anxiety fall, often to normal levels. Self-esteem, often low in chronic pain patients, also shows improvement once pain has resolved.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When people have long-term pain, what do they frequently display?
Ah, so.. psychological disturbance


Question: The most obvious difference between the brains of mammals and other vertebrates is in terms of size. On average, a mammal has a brain roughly twice as large as that of a bird of the same body size, and ten times as large as that of a reptile of the same body size.
Try to answer this question if possible: A mammal's brain is how many times larger than a birds relative to body size?
Answer: twice as large


Context and question: The Gothic vault, unlike the semi-circular vault of Roman and Romanesque buildings, can be used to roof rectangular and irregularly shaped plans such as trapezoids. The other structural advantage is that the pointed arch channels the weight onto the bearing piers or columns at a steep angle. This enabled architects to raise vaults much higher than was possible in Romanesque architecture. While, structurally, use of the pointed arch gave a greater flexibility to architectural form, it also gave Gothic architecture a very different and more vertical visual character than Romanesque.
What structural danger is offered by the Gothic vault?
Answer:
unanswerable
