Problem: Asthma:

Asthma as a result of (or worsened by) workplace exposures, is a commonly reported occupational disease. Many cases however are not reported or recognized as such. It is estimated that 5–25% of asthma cases in adults are work–related. A few hundred different agents have been implicated with the most common being: isocyanates, grain and wood dust, colophony, soldering flux, latex, animals, and aldehydes. The employment associated with the highest risk of problems include: those who spray paint, bakers and those who process food, nurses, chemical workers, those who work with animals, welders, hairdressers and timber workers.

What percent of asthma cases in adults are work-related?

A: It is estimated that 5–25%


Problem: Most early home computer systems developed their own 8-bit character sets containing line-drawing and game glyphs, and often filled in some or all of the control characters from 0–31 with more graphics. Kaypro CP/M computers used the "upper" 128 characters for the Greek alphabet. The IBM PC defined code page 437, which replaced the control-characters with graphic symbols such as smiley faces, and mapped additional graphic characters to the upper 128 positions. Operating systems such as DOS supported these code pages, and manufacturers of IBM PCs supported them in hardware. Digital Equipment Corporation developed the Multinational Character Set (DEC-MCS) for use in the popular VT220 terminal as one of the first extensions designed more for international languages than for block graphics. The Macintosh defined Mac OS Roman and Postscript also defined a set, both of these contained both international letters and typographic punctuation marks instead of graphics, more like modern character sets.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Skiing, snowboarding and mountaineering are among the most popular sports in Switzerland, the nature of the country being particularly suited for such activities. Winter sports are practiced by the natives and tourists since the second half of the 19th century with the invention of bobsleigh in St. Moritz. The first world ski championships were held in Mürren (1931) and St. Moritz (1934). The latter town hosted the second Winter Olympic Games in 1928 and the fifth edition in 1948. Among the most successful skiers and world champions are Pirmin Zurbriggen and Didier Cuche.
When were the first ski championships held in Murren?
A: 1931


Context and question: The eastern arm shows considerable diversity. In England it is generally long and may have two distinct sections, both choir and presbytery. It is often square ended or has a projecting Lady Chapel, dedicated to the Virgin Mary. In France the eastern end is often polygonal and surrounded by a walkway called an ambulatory and sometimes a ring of chapels called a "chevet". While German churches are often similar to those of France, in Italy, the eastern projection beyond the transept is usually just a shallow apsidal chapel containing the sanctuary, as at Florence Cathedral.
What is the sphere of chapels found in the eastern end of French chapels known as?
Answer: unanswerable


Question: Elevators with more than 30 m (98 ft) of travel have a system called compensation. This is a separate set of cables or a chain attached to the bottom of the counterweight and the bottom of the elevator cab. This makes it easier to control the elevator, as it compensates for the differing weight of cable between the hoist and the cab. If the elevator cab is at the top of the hoist-way, there is a short length of hoist cable above the car and a long length of compensating cable below the car and vice versa for the counterweight. If the compensation system uses cables, there will be an additional sheave in the pit below the elevator, to guide the cables. If the compensation system uses chains, the chain is guided by a bar mounted between the counterweight railway lines.
Is there an answer to this question: "Compensation" is the name of the system used for what type of elevators?

Answer: Elevators with more than 30 m (98 ft) of travel


QUES: Until roughly the 16th century, speakers of all the varieties of the West Germanic languages from the mouth of the Rhine to the Alps had been accustomed to refer to their native speech as Dietsch, (Neder)duyts or some other cognate of theudisk. This let inevitably to confusion since similar terms referred to different languages. Therefore, in the 16th century, a differentiation took place. Owing to Dutch commercial and colonial rivalry in the 16th and 17th centuries, the English term came to refer exclusively to the Dutch. A notable exception is Pennsylvania Dutch, which is a West Central German variety called Deitsch by its speakers. Jersey Dutch, on the other hand, as spoken until the 1950s in New Jersey, is a Dutch-based creole.

In what decade did people in New Jersey stop speaking Jersey Dutch?
What is the answer?
ANS:
1950s
